Renault Twin’Run gets 316bhp & pays homage to the Renault 5 Turbo

The Twin’Run is an extreme version of the next Twingo and manages to pay homage to the old Renault 5, with a thumping great V6 bolted in the middle and pumping out 316bhp and 280lb/ft of torque, enough to get to 62mph in 4.5 seconds and on to 155mph. The Nissan-sourced V6 gets mated to a SADEV six-speed sequential gearbox and comes with a limited slip diff to stop the tyres burning off when the going gets brisk. As well as endowing the Twin’Run with lots of power, Renault has also kept weight down to 950kg by using a tubular chassis, glass-polyester composite for the bodywork, lumps of carbon fibre and not a hugely laden interior.

New BMW M3 and M4 engine secrets laid bare

BMW's M division has lifted the veil of secrecy on the inline six-cylinder engine bound for its upcoming M3 sedan and new-to-the-range M4 coupe and convertible, revealing a potent twin-turbocharged 3.0-liter direct injection gasoline unit that produces an official 424 hp at 7,500 rpm and what officials describe as "significantly more than 369 lb-ft" of torque. The newly developed engine, known under the internal codename S55 B30, shares its 84.0 mm bore and 89.6 mm stroke with BMW's standard turbocharged 3.0-liter in-line six-cylinder direct-injection gasoline mill, the M55 used across the German car maker's lineup, endowing the aluminum block unit with an overall swept volume of 2,979 cc. This represents a sizeable 990 cc reduction on the engine BMW's M division's new unit replaces, the S65.
