Mercedes-Benz’s AMG division is planning to launch an indirect successor to the classic 190E 2.5-16 Evolution II by the middle of the decade.
The new four-door, which will rival the forthcoming Audi RS3 and BMW M1, will become the range-topper for a new model based on the next B-class. The car’s size and proportions were previewed by the F800 Style concept (pictured) at the Geneva show.
Set to slot into the AMG line-up below the next-gen C63 AMG, the new saloon, codenamed C117 EVO, will itself be influenced by the next CLS. It will have a coupe-like profile, taut surfacing overlaid with prominent crease lines, four frameless doors and a separate boot.
Overall length shouldn’t be more than 4500mm, placing it in the same-sized class as the 190E Evo II from 1990.
But while that car used a 2.5-litre four-cylinder motor fettled by Cosworth, the new car will get a supercharged 3.2-litre V6 that is already undergoing bench testing at AMG’s headquarters.
The new engine is based on the new M276, a turbocharged 3.5-litre V6 which will power the new CLS350. Instead of a turbocharger, the AMG version uses an electrically operated pressure wave supercharger. Insiders hint it will make close to 400bhp in production trim.
Also under development at Volkswagen, the pressure-wave blower uses pressure waves from the exhaust gas to boost the induction. AMG intends to use this idea in larger V6s and possibly V8s.
Up until now the pressure-wave process has been used mainly in large earth-moving and marine diesel engines, although Ferrari did look seriously at applying it to its Formula One engines in the early 1980s.
