Mercedes has released a new video showing the E63 AMG power sliding around a wet track. Boasting Top Gear-esque sequences, the clip attempts to lure you to sleep with relaxing music. Despite their efforts, the sound of the AMG V8 commands your attention.

Have a look at this pretty video featuring the new Audi RS5 as well as the original Ur-quattro (from 3:00 to 3:45) from the 1980s. Placing the cars together on a track connects them in an emotional and historical context, the Ur-quattro being the all-conquering rally god of its time while the RS 5 aims to sit atop its own modern segment. Don’t forget to pump up the volume.

It’s no coincidence, but the cars we’d most like to drive are often track-only race cars. Case in point: the BMW Z4 GT3. Powered by an M3 GT2-derived 4.0-liter V-8 engine cranking out 480 horsepower, it’s the leanest and meanest member of the Z4 family.

German tuners Hofele have released details about their new package of mods for the Audi A8 (D4). The kits release coincides with Audi’s reveal of the new version of their flagship four-door.

Hamann has decked out a new kit plus performance hikes for the Range Rover Sport. Called the Hamann CONQUEROR II, the new car features a new front bumper with four integrated LED daytime running lights, a light carbon fibre bonnet and four wide extensions constructed from light materials as a start.
