    This is number 4 of 25 Sytner-built Alpinas (one right-hand-drive car was also done at Buchloe) based on a 535i SE (chrome-edged bumpers, rear window blind). The 3430cc M106 ‘six’ was unchanged in capacity, but, thanks to higher compression and different cam, plus reprogrammed Motronic management, power was increased by about 40bhp and torque by 30lb ft or so. The suspension was reworked, 16in Alpina ‘turbine’ alloys fitted and the dash changed, along with the trademark stripes added.

    The car was restored about 10 years ago by an Alpina parts specialist, windows-out repainted and fitted with new bumpers. The result is superb, and even the Alpina wheels have been correctly finished with a 5mm overlap on the black centres. Fastened by two different types of security bolt, they are shod with well-treaded Kumho Ecstas, with a matching spare. The jack and wheelbrace are still present. Plus, the bootlid tray still has the full tool and bulb kit and – a detail to please ardent E28 fanciers – even the little plastic widget for winding the windows closed should the electrics fail. They all work, by the way, as you’d expect. Inside, the dashboard, headlining and glass sunroof were all replaced, as were the front door cards, and the rears recovered. The Alpina-striped seat upholstery shows no wear, just a little bagginess.

    It’s like new under the bonnet, with various items powder-coated and fresh stickers to the airbox, strut tower and a mint fusebox. The fluids are clean, to the right levels. Even the washer bottle and plumbing look new. It starts instantly with no smoke or tappety noises, feeling lively and free-revving. The ride, on Powerflex bushes and Bilsteins, is on the firm side of taut, plus it has lovely direct steering. The switchable auto responds correctly to E, Sport (in which it holds the gears longer and gives snappier changes) and intermediate slots for ice, snow or general hooning. It is as good as a Porsche Tiptronic and more intuitive to use. Coolant temperature is steady just under the middle of the gauge, the econometer works and the test button illuminates all the check lights on the service computer. It will come with a fresh MoT, and the registration number B10 ALP.

    SUMMARY

    EXTERIOR Superbly repainted, and set off with the signature Alpina decals.
    INTERIOR Excellent: quite a lot of it is new; a little stretch to the cloth trim.
    MECHANICALS Feel super-fit, and sorted.
    VALUE ★★★★★★★★✩✩

    For Rare, cool and fast
    Against Dare we say the automatic gearbox? It’s pretty good though

    SHOULD I BUY IT?
    Almost like a new one and so very drivable – addictively so. It might bring out your inner hooligan.

    ESTIMATE £6000-£8000

    Sitting somewhere between a standard E34 535i and an M5 or Alpina B10 Bi-Turbo lies the naturally-aspirated B10 and this looks like a nice example with 125k miles on the clock and one owner for the past 13 years. It’s just passed an MoT with no advisories so should be in fine fettle. £6-£8k looks like value for money, but it was on the Damaged on Condition Report in 1993, though it’s not listed on the HPI register. Perhaps a fine way into the rarer side of E34 ownership.

    New Order #Alpina-B10-3.5-E34 / #Alpina-B10-3.5 / #Alpina-B10 / #BMW-E34-Alpina / #Alpina / #Alpina-B10-E34

    It’s not often we come across an #BMW-E34 Alpina B10 3.5 as nice as this one and with an interesting past. Ordering a brand-new Alpina B10 3.5 straight from the showroom back in #1989 would have been quite an occasion. Driving one today reminds us why… Words: Simon Holmes Photography: Max Earey

    Walking into a BMW showroom and strolling straight up to the salesman to tell him you wished to purchase a brand-new 535i SE auto would have probably made both his and your day back in 1989. No doubt the salesman would be grinning from ear to ear at the thought of an easy £22,013.39 sale but think of the feeling you would have knowing that you were about to really surprise him when it came to selecting the option boxes. Limited-slip differential for £333.91? Yes, please. Sports seats? Well worth the £365.22. And metallic paint for £364.41? Add it on. But what’s that last one? An Alpina B10 3.5 conversion for £11,900? Over half the car’s value? Go on then…

    That would sure put a smile on my face and why not? Buying a £42,327.13 car in 1989 (when tax was just 15 per cent!) would be an enjoyable experience for anyone, but even more so when you’ve just ordered yourself one of the most exclusive and fastest BMWs money could buy at the time. Powered by a heavily tweaked naturally aspirated 3.5-litre engine the B10 was first launched in 1988 before the M5 was available in the UK, but even when the new M car was released one of the B10’s key selling points was the fact it was still available with an automatic gearbox. The M5 didn’t offer this option, which immediately meant the B10 had a niche market as the fastest 5 Series without a clutch pedal.

    Whilst the later B10 Bi-Turbo model essentially stole the show with its devastating performance the earlier incarnation was still an extremely capable car. It was based upon a standard 535i SE although Alpina required Sports seats and an LSD to be selected as options. In typical fashion, Alpina didn’t do things by halves when it came to extracting more power from the M30 3430cc six-cylinder. Tuning a naturally aspirated engine for big results is no easy task, so first of all the M30 was stripped to its bones and built up again with much lighter Mahle pistons at its heart.

    These helped raise the compression ratio to 10.0:1 over the original 9.0:1 for increased power. The cylinder head was ported for improved flow and fitted with modified valves at the same time, and then came a special high-performance camshaft designed specifically for fast road use. With those vital elements in place, a specially made tubular exhaust manifold was added, made from stainless steel, together with a complete freer flowing exhaust system. Last of all the Motronic ECU was given an Alpina defined remap to improve fuelling and the rev limit was raised to 6500rpm to make the best of it all.

    The result from all the work was an impressive 254hp at 6000rpm, giving over 20 per cent more power than a standard 535i. Indeed, some of the earlier UK cars that didn’t require catalytic converters made as much as 260hp. Torque was also up five per cent to 237lb ft at 4000rpm from the original figure of 220lb ft.

    Although the B10 gained a healthy dose of extra power and made it fairly high up the rev range the focus was set on ensuring it all came in a smooth, solid motion so there was no peaky power band to contend with. To help the B10 climb the revs and reach its peak power faster and to feel even livelier Alpina also changed the gearing in the rear axle to 3.73:1. The ratio change helped improve acceleration at the cost of a little extra top speed, which seemed like a fair trade off. Alpina claimed 62mph from rest was now achieved in 6.4 seconds, a very admirable figure for the time and enough to snap on the heels of the M5 model that would soon appear. Top speed was quoted from Alpina as being a solid 155mph, some 14mph faster than a 535i and, again, enough to trouble an M5.

    The engine came coupled to a five-speed manual gearbox as standard but importantly, as mentioned previously, the four-speed automatic could still be selected from the options list. Both transmissions worked well in their own way and offered different kinds of driving experiences.

    To go with the new-found power increase Alpina also focused on fine-tuning the already capable E34 handling package. The main aim was to improve the ride and level of grip. So working in conjunction with Michelin and Bilstein, the latter supplied gas-filled dampers to replace the standard items and tighten up the ride quality whilst still providing comfort. They were matched with shorter and stiffer springs designed by Alpina to limit body roll and sharpen up response. These changes worked together with the special low profile Michelin MXX tyres measuring 235/45/17 at the front and 265/40/17 at the rear.

    The larger diameter Alpina wheels were wider too – 8.5-inches at the front and 9.5-inches at the back. To finish off the package, on the outside there was a colour-coded lower front spoiler and the body was finished with a set of matching Alpina and B10 3.5 badges. On the inside there was a new design of Alpina steering wheel finished in leather and a build plaque to remind you that you were part of a privileged club.

    Although it was privileged club the B10 actually sold fairly well and 572 examples were built in the four-year production run, which was successful for an Alpina model of the time. However, as the youngest examples are 22 years old it’s hardly surprising that finding a B10 3.5 nowadays has become harder, particularly when it comes to sourcing one in good working condition. We were lucky enough to find this one for sale at classic car specialist KGF Classics, who specifically deal with desirable cars from the ‘80s and ‘90s. This particular example is in beautiful condition, and has just 57,000 miles on the clock so it’s about as good as you can find. To cap it off it’s got an interesting and detailed history, having been ordered in the summer of 1989 at John Clark #BMW in Aberdeen by one Lord Seafield, part of one of the wealthiest families in Scotland. The original invoice is still with the car, which is how we know the exact cost of the car listed at the start of the feature.

    Clearly, Lord Seafield wanted a car with some real performance but opted for the automatic, thus creating the ultimate effortless cruiser. He clearly took good care of it for the next 17 years he owned it, too, and in doing so it’s provided us with a chance to try an Alpina B10 for ourselves in all its glory some 20 years later.

    Finished in this striking burgundy colour with Alpina graphics in contrasting silver it looks stunning, and the beige interior is all original, complete with a 1980s #NEC car phone. Taking position on the driver’s sport seat I find the B10 possesses a quality all older Alpina cars seem to. There’s a specialness to them, a sense of occasion that isn’t replicated in other cars. Perhaps it’s their reputation or heritage or perhaps I’m simply a stickler for anything that’s a little different. Whatever it is, the original Alpina steering wheel and dials glaring back at me bring a smile to my face and one turn of the key has the engine burbling into life, the exhaust note lively and enthusiastic. I select Drive on the large, automatic gear selector, release the manual handbrake and set off slowly down the road.

    Immediate first impressions are based solely on how good the ride is. Having driven standard E34 535i models before I always find the ride way too soft and bouncy, even with Sports suspension. To be fair, most of these cars were on balloon tyres compared to the skinny numbers the Alpina rides on, but I’m genuinely impressed with how much firmer and crisper it all feels. The suspension actually supports the car’s mass and turning into corners, even at speed, gives very little body roll. It stays flat, staunch and confident but it’s not just stiffer, its feel reaches way beyond that. It’s beautifully balanced and the whole thing works as one to feel sharper and livelier.

    The effect extends to the steering which, again, I usually find lacks response on 535i models. Yet here the steering gives tremendous amounts of solid and satisfying feedback that you can’t help but miss in newer cars. Together with the suspension setup the whole platform feels wonderfully taut and harmonious. I’ll admit, I was expecting typically 1980s E34 road holding but this is an incredibly refined package and, to be honest, it’s caught me off guard. The engine takes a little longer to impress me. In the lower revs there’s plenty of grunt, as you would expect from a 3.5-litre, but that’s the point; there’s not actually a whole lot to differentiate it from a standard 535i. However, plant your foot further and as the revs build the engine answers the call.

    By the time you’re approaching the 4000rpm barrier things are really beginning to work together and you notice pace is building at a decent rate. There’s a nice soundtrack, too, and it’s all very smooth and undramatic in its approach towards the redline. It’s not exactly crazy fast but it’s certainly nippy in the higher rev range and there’s plenty of power to keep you amused. The engine isn’t entirely helped by the lethargic gearbox, which has three preset modes, yet even in Sport gear changes seem a little lazy. After an extended drive you soon get used to the gearbox and surprisingly, you still find yourself having plenty of fun with the power. It does a good job of returning to a gentle cruiser once you’ve finished your fun playing around with the rev range, too.

    I’m impressed by the B10; its fine chassis tweaks make it stand out and it’s easy to see the potential of how easily this car would have been able to devour country B-roads. It’s a world apart from a normal 535i and considering the changes from Alpina might seem subtle on paper they make a huge difference in the real world. It’s unlike an M5, though, which feels far more focused and involved whereas the B10 feels like a go between, especially with this gearbox. Although the automatic mutes the whole thing a touch the engine’s rev happy nature and the car’s gearing get around the problem. I’d like to try a manual version to compare against but I can see the automatic’s appeal at the time. No other car was able to provide such an effortless, fast and fun to drive platform. Of course, the modern day answer to this formula would be a big turbo diesel but that was a long way off. So would I have bought one back in 1989? Yes, especially to see that salesman’s face…

    E34 #Alpina-B10-Biturbo - a Taste of the Future.

    Alpina’s glorious B10 Bi-Turbo may well be 26 years old but it provided owners back then a glimpse of what the future would bring. Looking back on the glorious #Alpina-B10 Biturbo and why it was so far ahead of its time.

    You know those crazy concept cars from the Eighties that were all angles and glass, gullwing doors and digital instruments? The ones that had an electric motor, fourwheel drive and steering at both ends?

    That was how the industry saw the future of the high performance car 25 years down the line. However, if they’d really wanted to see what the performance car of the future looked, felt and drove like, then they could have done so right there and then, back in #1989 , if only they had visited a small German car manufacturer based in Buchloe. For there they would have found a car that very accurately replicated the typical high performance car of 2013.

    No sharp angles or crazy doors, just a normal saloon with four doors, adorned with a few subtle spoilers for a suitably aggressive appearance. No flashing instruments, just some conventional dials in a conventional dash angled purposefully towards the driver. No electric motors, instead a twinturbocharged, drive-by-wire multi-cylinder engine that, although big, might not be as big as you’d expect considering the performance on tap. Rear-wheel drive, not four, simply with some electronics to keep all the power in check.

    And the way it drove would have provided a similarly accurate taste of what was to come. Refined, smooth and comfortable most of the time but able to suddenly switch character, to excite and entertain whenever the mood took the driver, boasting an engine with huge, effortless performance thanks to lots of mid-range torque.

    You’ve probably by now got the point we’re trying to make here. Above is clearly a reference to the #BMW-E34-Alpina B10 Bi-Turbo, although it could quite easily have been the F10 M5 or highly-anticipated F30 M3 that we were talking about. Arguably it is Alpina’s first Bi-Turbo models that are more closely related to today’s M cars than stuff like BMW’s own E30 M3 and E34 M5.

    Obviously such advanced technology back then didn’t come cheap. It’s rumoured that Alpina spentthe equivalent of £2 million on R&D alone for this model, and so it shouldn’t (but probably still will) come as a shock to hear that E34 Bi-Turbos sold for the equivalent of nearly £150,000 in today’s money. Still, it made 507 of them between August 1989 and March 1994, so clearly Alpina’s achievements were understood by the wealthy.

    Let’s hope the M cars of today age as well as the #BMW-E34 Bi-Turbo, because, looked after, these B10s have a habit of feeling as fresh and tight now as they did when they left the factory. Obviously they will have been cherished far more than most BMWs but the difference between examples of the two is quite considerable in my experience. And this one, number 299, owned by Swiss Fredy Lienhard who runs a track car rental company based at the ’Ring, is no different. Hardly a surprise that it drives so nicely, really. The car is 100 per cent original even down to the decals, and has done only 120,000 kilometres (about 75,000 miles) in its life. It has only had two previous owners, too, although the second didn’t register the car so Fredy is actually down on paper as the second. And it has a full service history, with all work carried out exclusively at Alpina or BMW dealers. So it’s a good example, to put it mildly.

    I’ve never driven a brand-new E34. I wasn’t old enough to have done back in day and, well, there aren’t many brand-new ones around now. But pooling together my brand-new or nicely sorted BMW experience, I can say with some certainty that this one drives as near as dammit exactly as it would have done when it was built back on the 26 September 1991. And I mean very near.

    It is, I think I can safely say, exactly how every E34 owner wishes their own car would drive. You know, after all those little jobs have been done to it and everything has been replaced with new. The gearshift is firm and precise, if characteristically notchy, the clutch satisfyingly chunky but still easy to operate. The damping is excellent, the body never swaying or lurching or nose diving, and the ride is almost as quiet and supple as that of a new car’s.

    It feels big and butch, like a lot of brand-new M cars do, but it has a lot of things different about it too. The steering, obviously, is no way near as quick and direct as a modern BMW’s – although it provides far more feedback. The gear change is quite stiff, not as easy as the change in today’s M cars (if you can find one with a manual shift at all, that is). And the engine, although it feels mighty in a big, boosty way, it still has a little more lag and does sound a little more mechanical and busy than a modern turbocharged BMW powerplant.


    Obviously the big straight-six dominates proceedings once the Garrett T25s are fed with the engine’s waste, and once the turbos are giving their lot you aren’t really able to think of much else. It’s typically turbo, though far better than other turbo engines of the era, with boost starting to build at around two-and-a-half thousand (being a 3.4 ’six there’s still a not unreasonable amount of urge before this) and fully on song around a thousand rpm later.


    And then the driver is in for a treat, the torque seemingly building and building for the next two thousand rpm to a peak of 384lb ft, going on until around 6000rpm before the torrent starts tailing off. It must have been crazy to behold, this luxury saloon going so damn fast, back in 1991. And this one is particularly healthy, it turns out, as Fredy has a dyno printout proving this example makes more than standard; 389bhp, in fact. “Owners do that to check if the engine and the turbos are still healthy and spooling up,” he explains. “The Bi-Turbos tend to eat turbos.” No such problems here, clearly.

    Yet when the excitement is over, it turns into a smooth operating executive saloon – although there is still plenty to keep you interested, if in a very different way. It’s brilliant, the interior of the Bi-Turbo, full of cool little period Alpina touches that makes it feel special: the adjustable boost dial; the numbered plaque; the small digital readouts showing boost pressure, oil temperature and oil pressure; the very Nineties Alpina-branded mats; the wooden gear knob. They’re all so cool. Bi-Turbos obviously come well-equipped, so there are also Recaro multiadjustable leather seats that are heated, an electric roof and front and rear windows, OBC, cruise control, air-con and an electric blind.

    Your attention is drawn to Alpina touches when you’re standing outside the car, too. The stance, like all the best hot BMWs, is mega; the Alpina chin spoiler is subtle yet aggressive; and the colour combo of black with silver decals and wheels is pure class. Even the little red details of the badges work perfectly with the black. And the 235/45 front and 265/40 rear tyres stretched ever-so-slightly over the 20-spokes is pure ‘90s fitment perfection.

    “When the owner took me for a ride in it, the only thing I could speak about afterwards was this car,” says Fredy, remembering his first experience of it. “When I bought it, it really was a childhood dream come true. To me it’s a legend. I love the look of the #Alpina-B10-Biturbo-E34 and I love the fact that it’s like a race car with an executive car suit. The car came out when turbo cars were known to be very laggy, and this changed that, the two smaller turbos making it more driveable and better for daily use. It was a very modern car for its time for other reasons, too, because of the electronic stability programme and drive-by-wire throttle.” Although perhaps the technological highlight of the car is the auto-dimming rear view mirror: it doesn’t work by way of a gel between glass layers, rather it actually changes the angle of the mirror using little electric motors.

    “I didn’t buy this car to drive really, just to look at and to enjoy having!” admits Fredy, smiling as he realises himself how crazy that sounds, even if we can all understand exactly where he’s coming from. He goes on to redeem matters somewhat, though: “I do take it for the odd drive to warm it up and obviously I haven’t been able to resist an autobahn drive.” 315km/h on the speedo was the result of that rare little foray, so maybe it’s for the best that this awesome piece of automotive history is left safe and sound in the garage.

    The #1994 - #BMW-E34 #Alpina-B10-Biturbo road test.

    The #BMW-E34-Alpina-B10-Biturbo - Ferrari Testarossa performance, Silver Spirit silence. By Paul Frere Photos by John Lamm.

    From the very beginning, Alpina’s products have been based on cars from #BMW with which it operates in close cooperation. I have driven many fascinating cars from #Alpina and even owned one, but the 535i-based B10 Biturbo is surely the most impressive of them all: a comfortable 4-door that blends Rolls-Royce silence with Testarossa performance, with road manners to match. Only its bodyshell and basic suspension parts remain essentially as produced by BMW.

    When the car arrives at the Alpina works in Buchloe. Germany, the engine is completely dismantled. Forged pistons are fitted and all moving pieces rebalanced. The combustion chambers are remachined, and new valves (sodium-cooled on the exhaust side) and a new camshaft are fitted. The intake and exhaust systems are entirely Alpina. They include new exhaust manifolds supplying twin Garrett T25 water-cooled turbochargers with an integrated, electronically controlled wastegate feeding the engine through a large intercooler.

    Fuel injection and ignition are by Bosch Motronic. The entire exhaust system is made of stainless steel and includes no less than six metal-core catalysts with Lambda-Sond control. Maximum boost pressure is 11.4 psi, but a knob on the instrument console allows this to be reduced to 5.7 psi to avoid excess power on slippery surfaces. The result at full boost is an Output of 360 bhp DIN at 6000 rpm and mammoth torque 384 lb ft.

    As this is more than the standard #BMW-535i-E34 clutch and gearbox can take, a stronger Fichtel & Sachs clutch and a 5-speed gearbox, specially developed by #Getrag transmit the drive to the beefed-up rear axle, which includes a 25-percent limited- slip differential.

    Where else but in Germany can a speedometer needle edge past the 300-km/h mark? And what cars do it with as much ease and comfort as the #Alpina-B10-Biturbo-E34 ? Precious few. Alpina’s twin-turbo treatment furnishes BMW’s #M30 3.5-liter six with a whopping 360 bhp and 384lb ft of torque.

    Light-alloy 17-in Alpina multispoke wheels make room for larger- than-standard Girling brakes with 4- piston front calipers. Linear-rate springs are used all around with antiroll bars and Bilstein-damped front struts. At the rear, the Fichtel & Sachs shock absorbers also control the ride height, which is hydraulically adjusted by an electronically operated high-pressure system.

    This system is essential because the 3735 lb B10's camber is affected by suspension movements. And when the B10 reaches a maximum speed of 181 mph it's even more important. Excessive negative camber could cause the tires to overheat and fail at sustained speeds of this order. The B10’s tires are ultra-low-profile Michelin MXX2s on 8 ½ - and 9 ½ - in wide rims front and rear, respectively. The power-assisted steering is recalibrated to suit Alpina requirements. A special front air dam and rear spoiler are added to combat aerodynamic lift.

    The interior trim is specific to Alpina and incorporates the company's own fabric. A #Alpina-B10 buyer gets a choice of BMW-based or Alpina front seats, as well as a special steering wheel, polished wood door and console trim. Traction control is standard, and a switch enables the driver to override it. Air conditioning is also standard, along with a superb radio/cassette sound system.

    Acceleration in the standing-start kilometer (0.62 mile) is 24.7 seconds, faster than a Ferrari 348. a Porsche 911 Carrera 2 or 4 or an Acura NSX. But almost more impressive is the effortlessness - and the silence - with which the B10 Biturbo accelerates.

    The twin-turbo installation of the #Alpina-B10-E34 has spectacularly reduced turbo lag. Thanks to the low inertia of the two small turbochargers and to the electronic wastegate control, response is nearly immediate in almost any circumstance. Nor does the boost build with a bang. It rises progressively in a well-controlled manner, with 370 lb ft of torque already on hand as the engine reaches 3000 rpm. Torque remains above this figure until 5000 rpm, and reaches its peak of 384 lb ft at 4000 rpm.

    The B10 reached a maximum speed of 181 mph. At such speeds, the car feels entirely stable, with no suggestion of the front end getting light or any tendency to wander.

    Neither wind nor road noise is obtrusive. Cruising at 125 mph feels positively slow, and flooring the accelerator pedal catapults the heavy car forward-irrespective of whether 4th or 5th gear is selected-without the din usually associated with all-out acceleration from such speeds. The gearbox is another fine piece of machinery. It is inaudible in any gear, and its smooth action allows for some quick shifts.

    With such performance, the brakes are put to the challenge, and they do their job admirably. Handling is definitely of sports-car character, the B10 cornering quite flatly in a slightly understeering attitude that can easily be changed by reducing the throttle opening. Apart from a little vagueness around the straight-ahead position, the power-assist steering is excellent.

    The Alpina's comfort level was an-other bright surprise. The suspension is rather firm, inspiring a great sense of safety, but even at low speeds it does not feel harsh. How much low-speed harshness is perceived depends to a large extent on acoustics, and the B10's good insulation probably helps. This is one reason why Alpina chose Michelin MXX2 tires.

    The B10’s fuel consumption in dense Munich traffic averaged a remarkable 19 mpg. I averaged 100 mph from Hockenheim to the outskirts of Munich fora fuel consumption figure of 14.1 mpg, astonishingly economical taking into account that the engine’s full potential was used wherever possible. Even driven at those speeds, the range provided by the 29-gallons (80-litres) fuel tank should exceed 400 miles.

    What more could one wish for? Apart from the small steering problem and stiff clutch-pedal action, the #BMW-E34-Alpina B10 Biturbo E34 would truly be the perfect car.
