Alfa Romeo to launch 8 new cars in next 4 years – Alfa MiTo to be dropped

The Alfa Romeo Gloria (pictured) could point to a new Giulia Alfa Romeo has been stuck in the doldrums for quite a while, and is now in the sorry state of having just two cars on sale – the Alfa MiTo and Alfa Giulietta – both compact cars and both with front wheel drive. Not really Alfas, although they’re better than you might expect. But in a brave plan to turn Alfa Romeo in to a proper force again – a plan we reported was on the cards a year ago – Sergio Marchionne has revealed that Alfa is planning to launch eight new cars in the next four years and concentrate on proper RWD cars with proper driver appeal.

Honda AC-X Concept

The Honda AC-X plug-in hybrid sedan will form part of the company's seven concept vehicle strategy at the 2011 Tokyo Motor Show. From the images released by Honda, the AC-X appears similar in both size and proportion to the hydrogen fuel cell-powered FCX Clarity, with its a-pillars and windscreen base pulled far forwards, a smooth transition over its nose, screen, roof and rear deck and an elongated, sharply cut-off tail. Aerodynamic efficiency is clearly paramount.

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.
