F10 S5 Schmiedmann’s 532hp super saloon
The F10 #BMW-550i is unquestionably a modern muscle car. It’s big, it’s got a 4.4-litre, twin-turbo V8 and it’s fast. Not M5 fast but, with 407hp and 443lb ft of torque on tap, it’s certainly not a slow machine by any standard. There’s a but coming, though, and that’s to do with the N63 engine because, much like its smaller, turbocharged straightsix cousin, it’s an engine with plenty more to give if you’re up to the task of giving it a little bit of attention and Schmiedmann is definitely up to that particular task. The Danish BMW specialist is a multi-talented one-stop shop, able to supply replacement OE parts, offer servicing and repairs and it also carries a huge range of aftermarket parts so it was really spoilt for choice when it came to creating its S5 demo car and the Schmiedmann team really went to town on this build.
With that twin-turbo V8 at their disposal it’s no surprise that the engine has received plenty of attention but what is a surprise is just how much work has actually gone into it. You might be thinking that a remap would suffice, as that would give you some impressive gains, but that wouldn’t have done for Schmiedmann, the guys there are petrolheads after all, and when you’re building a company demo car you really want to show off your skills. That’s why this car has been fitted with Schmiedmann by Turbo.dk Signature Stage 2 turbos, upgraded standard turbos designed to cope with and produce a lot more power. They boast 15T CNC-milled 48/68mm compressor wheels, which are substantially bigger than the standard 42/56mm items, bigger turbine shafts, upgraded wastegate bushes, upgraded bearings and the turbo housings have also been modified. To go along with the uprated turbos, the chargecoolers have been equipped with a 75% larger radiator, and there’s also a set of Schmiedmann by Supersprint downpipes and a Schmiedmann by Supersprint exhaust system made from micro sandblasted stainless steel, with purposeful Schmiedmann-designed black, double-layer tailpipes.
All these mods needed the right performance software to accompany them, but that proved to be a lot more difficult than you might imagine. “The software was actually the biggest challenge of the build,” explains Schmiedmann’s Martin Thorup.
“When we had all the hardware ready the only thing we needed in order to get the power out was the ECU tuning – the car has a water-cooled Continental MSD85.0 ECU – but we found out that no tuner we know could get access to this ECU so they could reprogram it to our hardware changes. We tried to contact tuners all over the world but the answer was always the same: “It’s not possible, the ECU is blocked by a code that nobody can crack yet”. There was one famous German tuning company that claimed that they could do it, so we sent them the ECU but they also had to give up.
We then found out that almost all tuners worldwide got the reading and programming tool from a company in Switzerland. After speaking with a Danish tuner that had a good connection with the company in Switzerland, they sent two staff members over to Denmark to try to crack the code in our F10 S5 but they couldn’t and also had to give up.
“Now it seemed our only option was to change the hardware back to standard, and install a tuning box; that would bring about 65hp more than standard, but we wanted to hit at least 500hp. Then we got an idea: we called our business friends at Tuningbox in Belgium, and asked them if we could buy an “open” standard Tuningbox for an F10 550i that we would be able to program individually for the hardware changes we’d made on the car. They agreed and also sold us a programming tool for the Tuningbox; the S5 was then placed on the dyno and adjusted by the Danish tuner in co-operation with Tuningbox in Belgium by remote.” The herculean effort that Schmiedmann went to in order to get the software working with the mods on the car was worth it, as the end result of all that work is an amazing 532hp accompanied by a mammoth 563lb ft of torque, huge gains over stock and just huge numbers that push the Schmiedmann S5 into M5 performance territory. “But there is no doubt that the engine and the hardware have potential for much more the day when the ECU code gets cracked,” says Martin, “and we can program a lot more engine parameters,” at which point the S5 will become even more of a beast…
Power, as they say, is nothing without control, and while the F10 is a decent handling machine out of the box, it’s not exactly a sports car and throwing an additional 125hp at a chassis that was unprepared would leave things in a bit of a mess, so Schmiedmann has ensured that its S5 stops and handles as well as it goes.
The standard suspension has been replaced with a Bilstein B16 coilover kit, which offers a wide range of height and damping adjustment, resulting in not only much-improved body control but also allowing the Schmiedmann team to deal with the F10’s gappy arches, giving the S5 a serious drop. The brakes, too, have been attended to and the boat has been well and truly pushed out here, with a Schmiedmann six-pot BBK mounted up front with massive Zimmerman 400x36mm floating discs while at the rear a set of Zimmerman sport brake discs have been fitted in the stock size, as they’re still seriously hefty items on the 550i, and the brake calipers have been painted in Phoenix yellow to match the fronts.
When it comes to styling it’s fair to say that the F10 isn’t a bad-looking car but there’s certainly room for improvement if you want to make it stand out, so the warehouse was duly raided in order to give the S5 a far more menacing look and one more befitting of something so powerful. Up front you’ll find an F10 M5 front bumper with the 550’s foglights removed and coded out, and this is matched with a pair of M5 front wings with Schmiedmann S5 vents.
Motorsport II sideskirts have been fitted and further enhanced with the addition of Schmiedmann carbon streamers and there’s also a Motorsport II rear diffuser with cutouts for the beefy quad exhaust tips. You’ll also find a BMW M performance carbon boot spoiler and Schmiedmann has retrofitted the High-gloss Shadowline window trim along with adding black gloss double slat kidney grilles for the finishing touch. The wheels, meanwhile, are 20” Z Performance ZP.06s finished in Phantom Black, with polished spokes set against black painted barrels and lips for a striking effect, and while the 20s are needed to clear the massive front brakes, they’re also the perfect size for the big-bodied Five and really help to fill those cavernous arches.
You might think that, on a modern car such as this, there wouldn’t be much you could or would even want to do to the interior but Schmiedmann has made sure that interior on its S5 stands out from the crowd in just the right way. The most obvious mod is the steering wheel, a suitably exciting-looking Schmiedmann item with heavily-sculpted grips around the rim, beautifully hand-finished in Nappa leather and alcantara. The instrument cluster has been modified and now sports red needles and an S5 logo; there’s a black and grey sport pedal set and even the floor mats have been replaced with plush new ones that are extra thick and boast genuine nubuck leather piping with double red stitching.
Not only is the Schmiedmann S5 a magnificent mobile display of what the company can offer, it is also a serious piece of machinery, one which boasts M5-rivaling power, performance and presence, with looks that dominate the road. Schmiedmann has left no stone unturned in the creation of its S5 and the extremely impressive results speak for themselves.
“The end result is an amazing 532hp accompanied by a mammoth 563lb ft of torque, huge gains over stock”
