This behemoth is the Brabus B63S 700 6x6, a six-wheel drive G-wagen with 690bhp that’s been revealed at the 2013 Frankfurt motor show. Is the Brabus B63S just pie-in-the-sky concept car? No, it’s a real Brabus production vehicle, based on Mercedes AMG’s own mad G63 6x6.

Audi RS7 Sportback (2013) first official pictures

This is the new Audi RS7 Sportback, just unveiled at the 2013 Detroit auto show. It's an A7 Sportback given the hardcore RS treatment, meaning a 552bhp and 516lb ft 4.0-litre bi-turbo V8 that will sprint the RS7 to 62mph in 3.9sec. That's faster than the latest Porsche 911 – it seems life just got a bit harder for the Mercedes CLS63 AMG and BMW M6 Gran Coupe.

Tokyo Auto Salon pits performance autos against hybrids

The world's other big January auto show, the 2010 Tokyo Auto Salon, opened its doors to tuner enthusiasts in mid-month with a record 402 exhibitors. The Auto Salon fuses numerous styles, but the overriding theme this year was hybrid cars, with customized Toyota Priuses and Honda Insights at every turn. Good old-fashioned engine tuning is alive and well in Japan, where even new sports cars are being heavily modified, with cars such as the KRL Mitsubishi Evolution X and the HKS Nissan GT-R both boasting in excess of 600 hp.
