New Mercedes A Class: A 180 BlueEFFICIENCY Edition models launch

Mercedes are launching two new eco versions of the new A Class – the A 180 CDI BlueEFFICIENCY Edition and A 180 BlueEFFICIENCY Edition. Mercedes has had a play with the aerodynamics on the new A Class to lower the Cd value from an already very low 0.27 to 0.26 by partially covering the upper section of the radiator grill, adding aerodynamically shaped spring link coverings that improve the flow of air along the underbody at the rear axle and lowering the suspension by 15mm. Mercedes has also tweaked the generator management for more efficiency and had a play with the gearbox to make the ratios longer (which will help economy, but won’t do much for responsiveness).

The Great Date Car Debate: Top 10 date cars from his perspective--and hers

Here at AutoWeek, we've seen plenty of top 10 lists for date cars over the past few years. They all seem to have one thing in common: They're written by male bloggers whose most recent date was with a two-liter of Mountain Dew and a PlayStation 3. Since we have both men and women on our editorial staff, we decided to get a read on the subject of date cars from an actual representative sample of the dating pool.

New Audi S6 and S6 Avant (2012) Frankfurt Preview

New Audi S6 and S6 Avant (2012) at Frankfurt Frankfurt 2011 is going to be something of an Audi ‘S’ Fest, with four new 2012 ‘S’ models making a début, including these – the Audi S6 and the Audi S6 Avant. There’s little to choose between the S6 and S6 Avant in performance terms, just as you’d expect, with both cars featuring Audi’s new 4.0 litre TFSI V8 with 420bhp and 406lb/ft of torque (that’s the same V8 we will see in the Bentley Continental GT – and probably at Frankfurt too). That’s enough to take the S6 to 62mph in just 4.8 seconds, with the S6 Avant just the smallest bit behind at 4.9 seconds, and on to an electronically governed 155mph.
