Ahead of the official launch at the North American International Auto Show (NAIAS) in January, BMW have released the first details of the M3 Sedan and the M4 Coupe. Both cars share the same underpinnings and drivetrain, which includes a 425 bhp version of the familiar twin-turbo straight six. It comes standard with a six-speed manual gearbox, while a seven-speed, dual clutch gearbox is available as an option.
Hot on the heels of the first glimpse, Audi have now published more details and pictures of the new upcoming R18 e-tron quattro. It uses an evolution of the hybrid drivetrain that consists of a mid-mounted TDI V6 and a front mounted electronic motor connected to the front wheels. What is new is that the flywheel is not only fed by the electric motor under braking but also by a generator mounted in the exhaust system, which uses heat to generate energy. This is a similar technology as will be used in Formula 1 next year. So it is with reason that Audi considers the 2014 R18 e-tron quattro the most sophisticated racing car they have ever produced.
Rinspeed are a set fixture at the Geneva Motor Show, often showcasing the most spectacular concept car of the event. Their 2014 debut will be the XchangE, which can drive autonomously. Thanks to swivelling front seats, the occupants can have a face-to-face meeting at high speed.
