A new peak for the Mercedes-Benz E-Class Cabriolet

Even in this spectacular setting, the new convertible still deservedly commands plenty of attention.

The new Mercedes-Benz E-Class Cabriolet is perched nearly 3500 metres above sea level against a backdrop of snow-capped mountains. Here on the observation deck of Pointe Helbronner, the convertible’s rubellite-red paint — a deep, metallic burgundy — contrasts against the grey-and-white face of Mont Blanc, the highest peak in the Swiss Alps.

The cabriolet is the latest variant of the redesigned E-Class, which made its debut last year in sedan form and was later followed by a wagon, high-performance AMG models, and a coupe.

At a time when more buyers are eschewing cars for SUVs, Mercedes-Benz remains faithful to top-down driving with convertible versions of all of its core models, plus a handful of roadsters.

“In the 1980s, convertibles were practically non-existent,” says Frank Thiess, head of development for the E-Class Cabriolet. Now, he says, convertibles are as desirable as ever.

To reach its current resting place, the example under our scrutiny was airlifted onto its platform by helicopter — a precarious endeavour that required careful planning and 20,000 euros ($A30,000). The rest of us made our way via the Funivie Monte Bianco, a newly built cableway whose glass-and-steel station looms atop the rocky precipice like a villain’s lair from a James Bond film.

While many current Mercedes-Benz models are rife with creases and swoops, the E-Class Cabriolet reflects a simpler, pared-down design approach. “The side [of the car] is totally new, without the character line of the sedan,” says Uwe Haller, project manager for the E-Class Cabriolet’s exterior design. “The thinking now is, if it looks good, we take a line off. If that looks good, take another line off.”

The result is a clean yet elegant surface that allows smaller details to do the talking. These include a polished aluminum trim that runs around the beltline and flows into the interior. “If you look at the car from a drone, it looks like a yacht,” Haller says.

Haller is especially proud of the cabriolet’s tail-lights, which have a “crystal optic” surface that sparkles like thousands of tiny rubies. Not only are they beautiful, Haller explains, but they also emit the same intensity of light from every angle — something that’s particularly difficult to achieve.

Just as building a cableway that scales some of the world’s highest peaks requires superlative structural integrity, creating a well-mannered convertible is an engineering feat in its own right. To that end, engineers started with a stiffer body and added horizontal cross-members, a reinforced apron, and stronger side rocker panels. Back on the ground and in our own test cars, we felt the cabriolet’s sturdiness on a drive from Courmayeur on the Italian side of Mont Blanc, winding our way through France’s Haute-Savoie region toward Geneva.

The E400 model we tested was powered by a 3.0-litre biturbo V6 engine that is good for 242kW and 480 Nm. In concert with a new 9-speed automatic transmission, the E400 is well suited to cruising France’s fast highways and little two-lane roads, offering enough power to pass vacationers hauling boats headed for nearby Lake Annecy. Optional air suspension, meanwhile, keeps us grounded and comfortable.

The cabriolet is also fitted with the same semi-autonomous features as in the E-Class sedan, which can steer, accelerate, and stop the car automatically, given the right circumstances and road conditions.

We’ve raved before about the E-Class’ new interior, with its dual widescreen displays across the instrument panel and its luxe interior finishes. Our 25th-anniversary-edition cabriolet is fitted with all of these, plus gorgeous open-pore, elm-wood trim that pops among Macchiato Beige leather upholstery. Seats in the cabriolet have sun-deflecting properties that help keep them cool on this hot summer day, and rear seats fold down to accommodate an ever-growing cache of French cheese.

With the top down, wind is greatly reduced inside the cabin, thanks to windscreens above the windshield and in the rear. When the afternoon sun becomes too much to bear, the fabric soft-top can be raised in 20 seconds at speeds of up to 50 km/h.
