Mercedes-Benz SLS prepped to go GT3 racing

Mercedes-Benz AMG pulled the wraps off its new race car on Monday in Oaxaca, Mexico, scene of a commemoration of Mercedes' victory in the 1952 Carrera Panamericana. The new SLS GT3 is a modified Mercedes-Benz SLS intended to meet FIA homologation requirements for the GT3 class in series throughout the world. While it's not known what the production car will look like when it starts going to customers either this fall--according to the press release--or "before the start of the 2011 racing season," according to AMG's Thomas Rappel, the prototype shown in Oaxaca had a full roll cage, a new front skirt with splitter, rear diffusers and an enormous rear wing.

Bertone Jaguar B99 GT concept (2011) at the Geneva motor show

Bertone B99 GT – the racing version Next to the fully-trimmed B99 show car on Bertone's stand is an exterior mock-up of a GT2-class racing B99.  Two additional electric motors up front mean the GT has 972bhp all wheel drive capability.  A carbonfibre splitter, diffuser and flat undertray are matched with a massive bootlid wing.  There's enormous side-exit exhausts for the range-extender generator, a 100mm lowering job and a lurid green paintjob.  It’s an extreme way for Bertone to highlight the dual images of luxury and performance that Jaguar has in its heritage – particularly since there aren’t currently any saloons in the FIA GT2 series.  Perhaps they should have painted it in a '70s Broadspeed XJC touring car livery to get the full effect. More details on the Bertone B99 exterior design Bertone claims that it has modernized classic Jaguar three-box saloon design with the B99, with Bertone’s design chief Mike Robinson and his team drawing inspiration not just from past Jaguars, but the stealthy big cat that lends its name and image to the brand.  They coined the slogan "Cunning Glamour with Race-Bred Innovation” to embody the B99’s design… but from the two cars on the stand it looks like reconciling those disparate aims in the one vehicle may have been a bit beyond them. The roofline has been shortened and lowered in proportion to a conventional three-box body, inspired by a Jaguar cat stalking its prey.
