This week AMG introduced the company's latest high performance engine with the Mercedes-Benz S 63 AMG Showcar, which surprisingly did not appear in Geneva. Liveried like the legendary AMG racing car that won its class during the 1971 Spa 24 Hours race, it provides a preview of the upcoming production model. Under the bonnet it sports a smaller but turbocharged version of the much acclaimed quad-cam AMG V8 engine. Displacing just under 5.5 litre, it produces a hefty 571 bhp when fitted with the AMG Performance package. Another car that could just as well been shown at Geneva is this Citroen GQ Concept. It was developed exclusively for the Gentleman Quarterly Magazine.
Corvette will mark the company's 50th anniversary at Le Mans with the limited edition Z06 Carbon. This lightweight version combines the standard Z06 drivetrain with the suspension and brakes of the ZR1, which must give it superb handling characteristics. Only 500 will be built.
Although tucked away in a corner, the RUF RGT-8 was one of our favourite cars in Geneva. While it still uses a Porsche sourced body, it is powered by a bespoke V8 engine. The racing inspired unit features dry-sump lubrication and produces 550 bhp. RUF intends to start RGT-8 production in 2011. Another absolute highlight was the Lotus Evora 414E Hybrid. The car's advanced hybrid drivetrain looks like one of the most efficient options yet developed despite producing in excess of 400 bhp.
The German tuner companies were also well represented at the Swiss show. Brabus launched the E V12 Coupe and Techart had a first go at the Panamera with the Concept One.
In our Geneva article we were a little dismissive of the latest Hispano Suiza. A closer look revealed that the makers are very serious about producing the new Gallardo based coupe. In Hispano Suiza trim, the V10 engine produces 750 bhp. At the moment the car has not received a name. We were told that will be revealed within a few weeks.
