One Lap of the Web: Porsche 959s, the Alfa Romeo 4C and the Mercedes-Benz A45 AMG vs. the BMW M135i

We spend a lot of time on the Internet -- pretty much whenever we're not driving, writing about or working on cars. Since there's more out there than we'd ever be able to cover, here's our daily digest of car stuff on the Web you may not otherwise have heard about. -- When initially produced to satisfy FIA homologation requirements in 1986, the Porsche 959 was the world's fastest street-legal production car.

The first photo of the baby swoopy-coupe Mercedes CLA45 AMG has been revealed ahead of a New York Auto Show debut in a PS4 Driveclub release. The car that Mercedes hope will give it the edge over BMW and Mercedes in the hot baby premium market – the A45 AMG – has already been revealed, and it looks very promising. But although we’ve got the A45 AMG and all its specs already, we’re yet to see a photo of its swoopy-coupe sibling – the Mercedes CL45 AMG – even though the new CLA range has been revealed.

Gemballa Mirage GT Carbon Edition revealed

Gemballa Mirage GT Carbon Edition Uwe Gemballa and his team are probably the world’s best Porsche Carrera GT Tuners. There have been a number of tuned and pimped versions from them in the last few years (you wonder when they’re going to run out of donor cars  – there were only 1270 ever made), but this one looks particularly good. Based on a standard donor Porsche Carrera GT, the Gemballa Mirage GT Carbon Edition gets a power increase of around 50bhp, taking it to 670bhp (not as mad as some of the Gemballa Carrera GTs have been) and 470lb/ft of torque.
