Jaguar F-Type Coupe caught on video at Nurburgring

The Jaguar F-Type Coupe (pictured) testing at the Nurburgring The new Jaguar F-Type is a fine looking car, but the F-Type Coupe looks set to be the real looker, and we shouldn’t have to wait too long before the coupe hits a motor show (probably Frankfurt in September). Ahead of that reveal – with a likely on-sale date of early 2014 – Jaguar are out playing with the F-Type Coupe at the Nurburgring, blatting it round the ‘Ring’s unforgiving surfaces and bends to shake the last niggles out before launch.

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).
