Aston Martin CC100 Speedster concept

The Aston Martin CC100 Speedster concept has been built to celebrate the centenary of the British brand at the Nürburgring 24 Hour race. Apparently inspired by the beautiful 1959 DBR1 racecar, the CC100 apparently also gives some clues as to Aston's upcoming design language, particularly around the grille, with its prominent insert and the treatment of the side strake, which here becomes a more integral part of the wheel arch and fender. The car was designed in Aston Martin's studio in Gaydon, with its bodywork the responsibility of chief exterior designer Miles Nurnburger.

Porsche Macan gets 2.0 litre 4-cylinder petrol engine

Porsche Macan gets 2.0 litre 4-Cylinder petrol engine The new Porsche Macan looks set to change the rules for the compact SUV market, with class best handling and dynamics and performance that beats many a focused hot hatch. But despite beliefs Porsche would offer its first 4-cylinder engine in a generation at launch, the only engines on offer were a 3.0 litre diesel in the Macan S Diesel, a 3.0 V6 Turbo in the Macan S and a 3.6 litre turbo in the Macan Turbo, with expectations that the Macan wouldn’t get a four-cylinder engine util the end of 2014. But it looks like an early arrival for the four-pot Macan with news it’s getting a new 2.0 litre 4-cylinder petrol engine which delivers 237bhp and 258lb/ft of torque, enough to get the Macan to 62mph in 6.9 seconds and offer official economy of 37.6mpg.
