MERCEDES E500 COUPE

Take one pillarless Merc coupe and add a big-hearted V8. A classic recipe, but does it taste good? PH's Matt Rigby finds out

The E500 is a cruiser, but it's game on B-roads

The boys and girls at Mercedes would like me to tell you lots of things about the new E-class saloon and coupe.

They would like me to mention the 17,000 virtual crash tests, they'd love it if I wrote about the new piezo injectors on the diesel engines, which work 2000 times faster than the blink of an eye and are accurate to within 20 microns, and they'd be pretty chuffed if I slipped the fact that the new E-class uses carbonised olive stones to filter fuel as it goes into the tank.

...as this shot proves

The trouble is that the most interesting thing about the new E-class coupe is the only bit of tech that isn't new - the 383bhp, 5461cc V8 is the only engine carried over from the old E-class/CLK range, so I can't mention any of that.

Joking aside, though, the engineering effort that's gone into the development of the new E-class coupe is deeply impressive. Mercedes has been stung by criticism of the quality and reliability of the previous E-class and CLK, so it wants to make damn sure the new one is as solid as a Mercedes should be.

With a development programme that covered the same distance as 44 round trips to the moon, the new E-class should live up to expectations. Initial impressions are certainly promising. The shut lines are spot on, the door handle operates in a satisfyingly meaty manner and, once inside, the dash plastics, leather seats and general interior trim definitely owe more to traditional Mercedes solidity than they do to the almost downmarket-feeling cabin of the last CLK. The rather bluff cabin architecture won't be to everybody's taste, but its quality is unquestionable.

Perhaps the best thing you could say about the shape of the new E-class Coupe is that it's striking. Styling is a subjective thing, but there can't be many eyes out there that think the new Coupe is a thing of beauty.

Gerd Schoettke, team leader on the design of both the E-class saloon and Coupe probably wouldn't disagree - this car is about purpose rather than pure aesthetic beauty. "The coupe is more sporty, more defined and more passionate," he says. "The way the convex surfaces meet sharp lines is similar to what we've done in the S-class and C-class, but it's more obvious, more aggressive in the E-class Coupe. It's like a Stealth bomber, the sharp clear lines and the surfacing treatment. Not that we literally wanted to build a weapon you understand," says Schoettke (nervous laugh, don't mention the war, etc). "But you get the essence."

The other major aspect of the design is cohesion. "We wanted the exterior shapes to flow seamlessly into the interior shapes," Says Schoettke. And they do. The only minor issue is the tiny quarterlight at the trailing edge of the frameless windows, a compromise to do with the positioning of the fuel tank.

Out on the road you can immediately see why Mercedes has seen fit to let this engine live on virtually unchanged. It's mild-mannered at idle and around town, yet get it working through the smooth seven-speed auto (in sport mode or, better still, using quasi-manual paddle-shift so you can hold onto gears for longer) and the E500 Coupe displays a fair old turn of speed, accompanied by cultured, growling yowl, especially as it approaches its 6000rpm, peak power point.

One big - but well behaved -  V8

Unlike the new E-class saloon, there will be no AMG version of the E-class coupe, so the E500 is as powerful as a two-door E-class is going to get. Still, with the sprint to 62mph dealt with in 5.2sec, and 383bhp and 391lb ft of torque on tap, you're unlikely to feel short-changed. After all, the old naturally aspirated CLK55 AMG could only muster 367bhp.

Mercedes has seen fit to send us on a varied route around the south of England for the launch of the E-class, starting off from the Mercedes-Benz World uber dealership in Brooklands and, as suburban roads and dual carriageways give way to bumpy, twisting Sussex B-roads, we get our first opportunity to really stretch the E500 Coupe's chassis. This is not an out-and-out sports car - this is not an AMG model, after all - but the big E isn't afraid to tackle the twisty stuff.

The E500 Coupe feels like a big car - a definite notch or two larger than a BMW 3-series Coupe - but it never feels unwieldy. The fact it's 24 per cent stiffer than its predecessor no doubt helps, as does the surprisingly good body control, although we'd leave the sport switch for the suspension off as it firms up the ride to the point where it begins to lose damping composure over particularly bumpy roads.

The variable ratio steering rack is also an unexpected success. Yes, it's a touch light and detached at low speeds, but that suits the car's laid-back character. And should you decide to have a mad 15 minutes, the steering weights up nicely when you begin to throw the E500 hard into corners.

The E500 Coupe is certainly no hardcore performance car, and it's a shame that it won't spawn a successor to the sublime CLK63 AMG Black Series, but as a relaxed cruiser that can pick up its skirts when required, the E500 coupe isn't half bad.
