Giant road test #BMW-635CSi-E24
The two luxury coupes from #BMW
AG and #Mercedes-Benz
are not only impressive with shapely elegance. As expensive top models they combine luxury with performance. On the Boulevard of longing drive them way ahead.
What a nice car, I muse, while the BMW 635 CSi E24 slowly moving in its me. I sit in the Mercedes 380 SLC, its contemporary counterpart, both with exactly 218 hp. Both once with a price of just under 60 000 marks as expensive. The six is a six-cylinder, which follows the SLC Daimler privilege and provides an eight-cylinder, whose supple sovereignty is supported by a four-speed automatic.
I look through the wide, but low Mercedes-windscreen on the shark-like face of BMW. The typical brand dual headlights act not aggressive, but determined the distinctive kidney is modeled perfectly in the center. It is stamped from the plate, and not merely a cheap panel as detailed in the later sevens.
The beautiful BMW turns a wide circle arc in the courtyard of fairgrounds in order to place next to my Mercedes. Here I see clearly its elegant profile. I notice the low waistline with the large side windows as well as the bold wheel cutouts on.
The slightly short wheelbase, otherwise like criticizes the six acts from my perspective hardly disturbing. True beauty, I think, always has something to do with sexy imperfection. Deep relaxed I sit in the Mercedes on a wide blue leather chair, have before me the large star-wheel with the strange cattle engraved around the rim.
Even a mundane SL or SLC is here the common 200D is, there is not a privilege of athleticism - but the tachometer.
Sound and form in harmony
The frameless side window of the silver blue SLC is half open. So I hear the sonorous sound of the BMW unobtrusive, gently modulated by only one shift. His driver rotates, probably inspired as well, cocky a few circles too much. It is the perfect accompaniment to the attractive form, this unheard cultured shakes the whole force of its 304 Newton meters casually from the front pipe.
The interior of the Mercedes animated indeed to such contemplative viewing of sound and style. Dignified burled walnut, blue, light patinated leather with intense odor and familiarity that radiates all, also just been criticized steering wheel calm. The SLC is as an Abraham-lap, which makes you forget a lot of kilometers, but also defeated an accelerated procedure. From the rugged beauty of the SLC I've always been convinced even with car connoisseurs with a strong sense of aesthetics I had to justify it often.
When SLC running length compared to squat SL Roadster something of beautiful, and the proportions jubilant 36-centimeter longer wheelbase.
Even the louver windows, derided by others as a styling gimmick, I find downright erotic and consistently. For lamellae, if you will, can also be found in the rear lights, the radiator grille and in the basement of the profile again. The almost dome-shaped rear window of the Mercedes also is one of the specific details of this extravagant form that created chief stylist Friedrich Geiger. Paul Bracq, in earlier years of Mercedes-services nor father of pagoda, Stroke Eight and tailfin Coupé, drew the six, who despite their beauty offers less formal extravagance, but polyphonic harmony as the SLC.
The irrationality of the V8
The photo tours on the open fairgrounds be completed with restrained dynamics, no tire squeal, no kickdown. The automatic wins just once in third gear, their shifts are barely noticeable, speeds above 2500rpm hardly be achieved on the smooth asphalt Fair. My SLC obeys precise, accelerating gently, but firmly, steers easily with a little game about the central position, also comes very familiar and Daimler-typical. Acoustically it pleased me even more than the BMW, the casual-cool flap-flap-flap of the rather low volume aluminum eight-cylinder makes a nice accompaniment to quite emotional feeling of the heavy car. Got serious about only later, on the highway.
Only then I will give him the spores to use his time in proverbial tests revving to rapid acceleration. I want to hear when the soaked Flap-flap-flap a hoarse staccato, and sense when the shifts are tougher. No one believes that under the beautiful bodywork of the SLC, the Stroke Eight chassis infected. It has with its rugged wishbones front and semi-trailing arms rear reserves without end. Although he was raised to brave understeer, could beat him at long-distance rallies like the Bandama transverse drifting on gravel roads.
Finally switch to the long-awaited BMW six that will catch me again, by neutralizing my SLC euphoria slowly. I even had an E24, a mild 628 CSi of the first series, of course, with ZF three-speed automatic (ZF3HP 22). Our 635 CSi comes the second series, uses a platform already more mature in quality and driving dynamics fives E28 instead of playful E12 with its pronounced tendency to oversteer. I sit much higher in BMW, the ambience is dominated despite leather of cool functionality. The steering wheel is exaggerating it so, it seems strange mannered.
For sheer driving pleasure
But I feel nevertheless probably already with its dominant driving position affects the 635 CSi gripping. The large bulbous, super-elastic six-cylinder, which you can also drive in third gear, pawing already just above the idling speed with the powerful hooves. He wants to show what it can do, and with him the whole six-ser.
Sometimes I look instinctively to first gear left behind, but the Getrag five-speed gearbox a protected and no sports transmission. The handling of the nimble BMW is clearly better than that of almost ponderous Mercedes - he looks much more alive, the shorter wheelbase provides advantages in agility, the steering is direct and the car feels much total curve willing to.
The switching cars irritates course much more for turning the gears, subjectively created when 635 CSi the impression significantly more overwhelming temperament. The running gear, MacPherson struts in front and oblique handlebar rear, bought streets not position by hardness. Again, the six remains exemplary harmony. He is a sports car, but not an ascetic, the feeling of space front came luxuriant, the build quality is solid.
Nevertheless, it remains a typical BMW, as the SLC is a typical Mercedes, with more opulence in the cylinders and in space, rather than command Lounge Chair armchair. At the end of the SLC wins the duel just because he is the better GranTurismo, and because I'd rather go with him from Hamburg to Milan.
I almost forgot what is for a racy car of sixes. The back - torrential form, the high driving dynamics, the exciting motor. At 635 CSi of Sport weighs - dare in Gran Turismo. When formally equally enchanting SLC is reversed. Despite the actual superiority of the BMW my heart beats for the V8.
The 635 CSi is a luxurious sports car and the 380 SLC a sporty coupe. Motor Klassik editor Alf Cremers.

1 length runs, the slender silhouette of SLC also benefits from lush wheelbase. 2 Melodious 3.8-liter V8 from light metal in the early version with 218 instead of 204 hp. 3 The SLC is a true four seats, not scarcer 2 + 2, part in blue leather. 4 A beautiful face, chrome instead of aerodynamics, headlamp washers as a fine extra. 5 The 107er has pioneered the new star designs with. the typical profile luminaires. 6 air, leather, burr walnut, the SLC-feel-good interior.
Mercedes-Benz 280-500 SLC
The SLC is a relic of time before the rust prevention was improved when 107er. The complex technology is not to be underestimated.
Before buying you should definitely pay attention to bubbles in the paint which are manifested mainly on the headlights, in the lateral games, in the rear wheel arches and the area of the rear side portions of the rear window. Here a duck to swan is often painted with a new selling paint - that goes for Roadster and Coupe. Rust problems manifest themselves when 107er also the boot floor, on the A-pillar, the side sills, at the jacking points and at the tips, where they flow into the wheel arches.
Recommendable are the eight-cylinder with cast iron block, not only because they provide with good care extremely high performance, but also because of its wonderful bass-heavy sound. The problem child mimes the DOHC six-cylinder M110 whose elaborate cylinder head must be overhauled frequently at 200 000 kilometers. For such an overhaul one will go after all the 4000 Euro. A typical problem is the excessive play in the steering, it is a full-proposed steering gear fault. After long periods the fuel injection (D or K-Jetronic) can cause problems.

6 Check Control in Italian: Is the oil level?
BMW 630 CS and 635 CSi Early sixes are very susceptible to rust. The second series from 1982 are located not so much love for detail, but is much better in quality and rust prevention.
Especially from the early models up to 8/1977, which were built entirely by Karmann, had only a few receive. Rust is found mainly on the fenders, the floor plates in the engine compartment and the front spring strut domes. To inspect the rear wheel arches and the spring dome, the trunk liner is removed. Besides - the help to look at the moldings and bumpers, because here replacement is expensive. From little things like fatigued gas pressure regulators of the bonnet, defective motors for window regulators and sunroofs or frayed leather seats and the six will not be spared.
The six-cylinder M30 is practically just go on forever - if one starts with regular maintenance and the engine is not cold chasing what provokes cracks in the cylinder head. Pay attention to rattling noises, because that might indicate broken-camshaft, rocker defective or worn rocker arms. Bearing failures are very rare, since the crank mechanism is designed such that it without grumbling turbocharging or the high-performance four-valve head from the M1 and M 635 CSi endures. Are they well treated, then keep the Getrag manual transmission and the ZF automatic transmission as long as the motor.

Technik replacement is easy to get on the E24. The second series from July 1982 shall be based on the widely used E28 fives, and there are equal parts with the first sevens. The early models with E12 technology prepare few problems except for equipment and trim.
