Maybach, or not Maybach? That is the question.

Maybach - off to Gaydon? Actually, whether to keep Maybach on the Daimler life support system is a question that has taxed the brains of many a Mercedes exec,  almost since the Maybach brand got its revival under Mercedes and turned in to a cross between a stretched old S-Class, a Playstation and a glitterball. Because despite the efforts of Mercedes to position the Maybach above the S-Class – and in to competition with Rolls Royce and Bentley – the Maybach has somehow conspired to be less desirable than the S-Class.

Mercedes SLS AMG E-Cell (2010): the electric SLS

Following the unveiling of Tesla's updated Roadster 2.5, Mercedes is showing off its iteration of an all-electric sports car: the SLS AMG E-Cell. While the regular SLS pumps out 563bhp and 479lb ft from its 6.2-litre V8, the SLS E-Cell has four synchronous electric motors, powering all four wheels for a combined output of 392kW (equivalent to 526bhp) and a mammoth 649lb ft of torque. Crucially, all of that power is accessible from zero revs, allowing the E-Cell to sprint to 62mph in four seconds dead.

CCS/GM E-Flex project

Cadillac V-Flex Evan Mai Evan Mai presented the Cadillac V-Flex, a mid-engine electric race car that uses GM's E-Flex platform in a new configuration and advances Cadillac's art & science design language.  The race inspired proportion and layout of the V-Flex draws heavily from Le Mans prototype and F1 cars. Power would come from an electric motor with a range extending internal combustion engine. The Li-ion battery placed in the bottom center of the vehicle could be swapped from underneath the car during pit stops. Aluminum heat sinks in the rear efficiently dissipate heat away from the motor and battery while performing as a rear spoiler.  The front grille serves to communicate the Cadillac design philosophy and also serves as a functional aerodynamic enhancement.
