BMW has revealed details of a new M340i xDrive model, which will serve as the range-topping version of the latest 3 Series and will debut at the Los Angeles motor show this month.

Based on the new BMW 3 Series saloon that was unveiled at the Paris motor show last month, the M340i uses a turbocharged straight-six petrol engine developing 375hp and 500Nm of torque. The manufacturer claims that’ll power the M340i from 0-60mph in 4.2 seconds.

BMW also states that the M340i will return 37.6mpg on the combined cycle, with official CO2 emissions of 172g/km.

Drive is sent to all four wheels via an eight-speed automatic transmission. Although the M340i is given all-wheel drive thanks to BMW’s xDrive system, the car has a rear-wheel bias for added cornering ability.

It also benefits from a standard-fit electronically controlled locking differential, which enhances the traction levels.

A full M-Sport brake set-up comes as standard, with 348mm front discs and 354mm rear discs sitting behind 18-inch alloy wheels to provide a good amount of stopping power. Larger 19-inch wheels will be available as an optional extra.

Exterior styling touches have been applied to the M340i to help differentiate it from the rest of the 3 Series, with features such as a mesh-design front kidney grille, rear spoiler and grey metallic exterior mirror caps enhancing the car’s look.

Inside, the M340i gets sport seats, a leather-trimmed steering wheel with gearshift paddles and front door sills with the M340i lettering.

No prices have been announced yet, but BMW has stated that the M340i will make its market launch in Europe next July.
