2013 Mercedes E Class Facelift: The Video

We have the first video of the 2013 Mercedes E Class facelift showing the changes Mercedes has made more clearly. Not just the usual nip and tuck you’d expect in a mid-cycle facelift, but real sheet metal changes and proper upgrades as well as the usual lights and bumpers stuff. But however many photos we publish of the 2013 E Class, nothing really gives you a feel for the changes until you see them in the flesh or on the move.

Volkswagen XL1

This, remarkably, is the production version of the Volkswagen XL1, the most fuel-efficient production car in the world, a car we'll see in Geneva in a little over a week. Barely changed from the concept version shown at the Qatar motor show two years ago, the production XL1 is the first production result of VW's 1-liter project – to design a car that uses less than 1l/100km (282.5mpg imperial) – that started with the lozenge-shaped, tandem-seat 2003 1L and the later L1 of 2009. The XL1 actually beats that by sipping just 0.9 liters with CO2 emissions of 21g/km.

Audi RS5 (2010) first official pictures

This is the new Audi RS5, a £60,000 super-coupe with a high-revving 4.2-litre V8 and a 174mph top speed. It's Audi's riposte to the BMW M3, and we'll see it in the metal at next week's 2010 Geneva motor show. Under the bonnet is the same naturally aspirated 4163cc V8 that powered the old RS4 and is currently found in the R8, but Audi’s Quattro GmbH division – responsible for all of Ingolstadt’s RS models – has squeezed an extra 30bhp out of the engine. That means the high-revving, direct-injection 4.2-litre V8 produces 444bhp at 8250rpm, along with 317lb ft from 4000 to 8000rpm.  That power is sent through a seven-speed S-tronic gearbox to all four wheels, and with the Launch Control system engaged it’s enough to propel the 1725kg coupe to 62mph in 4.6 seconds, before powering the RS5 on to its 155mph limiter.
