‘I wish I’d designed the Mercedes-Benz W154’

I am full of admiration for the Mercedes W154. I believe in elegance and simplicity; a lot of people confuse complex with sophisticated. And if you look at the Mercedes, you’ll see there’s nothing to it. That’s the sort of grand prix car I like; one where every single part fulfils two, if not three, functions rather than there being brackets on brackets. It’s very pure. While that period’s Auto Union has a lot going for it too, you can almost say it was fundamentally wrong: its proportions weren’t right. The ratios of engine weight to chassis weight, and torque to grip, and all those other things, were such that it was never going to be a nicely balanced and complete car. I think one thing you really need to do when designing a racing car is integrate the engine, the chassis and the gearbox correctly, because I don’t like crude cars with fabulously powerful engines, and I’m unimpressed with cars that have very sophisticated chassis, loads of grip and no power so they’re flat out all the way round. I admire a nice balance, and the Mercedes had a nicer balance than the Auto Union.

A good balance between power and grip wasn’t an option because they hadn’t yet invented proper tyres, though they had invented massively powerful engines. But having a car like the mid-engined Auto Union with the driver sitting on the front axle, a massive engine stuck out the back — such that, by the time the driver noticed he was oversteering, he was at 45 degrees — didn’t, for me, bring balance. Yes, having the engine at the back meant it was ahead of its time, of course. But then the Jensen Interceptor FF was more advanced than the Audi Quattro. It had anti-lock brakes and four-wheel drive and the engineers said, ‘This is the future’, but unfortunately it was 20 years before customers said they wanted it. I am not saying the Auto Union wasn’t the right answer, but it certainly wasn’t developed into the right answer. Maybe it would have been in time.

It’s difficult to compare those two cars because it’s an era before my time. And the thing I admired about the Merc wasn’t its concept, it was its execution. It was sophisticated, but it didn’t have a billion bits on it. You look at the 1950s W196 and it’s got variable inlet trumpets, and there’s bits of pipe and bits of tube all over the thing. You look at the W154 and it has an elegant tube frame, and you’d have serious trouble finding anything in there; it looks like there’s nothing surplus to requirements.
