London Taxi maker Manganese Bronze bought by China’s Geely

China automotive giant Geely has bought Manganese Bronze – makers of the iconic London Black Cab – in an £11.04 million deal. The iconic London Black Cab has been an accident waiting to happen for years, as under investment in making the Black Cab fit for the 21st century saw competition – like the Mercedes Vito Taxi and the Nissan NV200 Cab – start to offer serious competition to the taxi that identifies London. Despite an investment by China’s Geely – when Geely bought 20 per cent of Manganese Bronze, makers of the Black Cab – and the bulk of the Black Cab being produced in China and bolted together in the Midlands, the final nail in the coffin for Manganese Bronze was the recall of 400 TX4 cabs over a steering fault.

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.
