The new BMW M340i xDrive Sedan: World premiere at the Los Angeles Auto Show 2018.

Standard features: 8-speed Steptronic sports transmission and BMW xDrive with rear-wheel bias.
The BMW M340i xDrive Sedan comes as standard with the 8-speed Steptronic sports transmission of the latest generation, which is characterised, amongst other things, by an optimised hydraulic control system and exceptionally high shifting dynamics. Short ratios for the lower gears improve acceleration and the Launch Control function can be used for accelerating with maximum dynamics from a standstill. Shift paddles on the steering wheel facilitate manual gear selection at any time.

With fully variable power distribution between the front and rear axle, the intelligent four-wheel drive technology featured by the BMW M340i xDrive Sedan ensures maximum traction, agility and vehicle stability. The rear-wheel bias of BMW xDrive supports that brand-typical driving experience and is particularly strongly effective in the driver experience control modes SPORT and SPORT+. The targeted transfer of drive force to the rear wheels enhances agility when steering into bends.

Furthermore, the BMW M340i xDrive Sedan is equipped as standard with the M Sport differential. The electronically controlled, fully variable rear-wheel locking function noticeably contributes not only towards an increase in traction, but also enhances stability and agility of the vehicle.

M-specific suspension technology transforms performance into dynamics.
The construction concept used for the suspension of the new BMW 3 Series Sedan offers the ideal prerequisites for sporty handling. The components of the double-joint spring strut front axle and the five-arm rear axle, both of which have been optimised in terms of weight and stiffness, enhance cornering dynamics and steering precision, as do the larger track widths and optimum wheel camber angles. In addition to a vehicle lowering by 10mm, the standard M Sport suspension of the BMW M340i xDrive Sedan comprises M specific elastokinematics and the new lift-related damper control function. The Adaptive M suspension with electronically controlled dampers is also optionally available. 

A further integral part of the M Sport suspension and the Adaptive M suspension is the Variable Sport Steering feature, which supports agile cornering with outstanding feedback as well as spontaneous and precise response.

Combining an extremely sporty set-up – headlined by short pedal travel and a distinct pressure point – the M Sport brake system, which also comes as standard, provides effective stopping power. The M sport brakes achieve this with a more direct ratio as well as a different hydraulic configuration including four-piston, fixed calliper brakes and 348 millimetres discs at the front and single-piston, floating calliper brakes with 345 millimetres discs at the rear. The blue-painted brake callipers bear the M logo.  Standard 18-inch M light alloy wheels are combined with mixed tyres. Tyres of the format 225/45 R 18 are mounted on the front wheels, whilst size 255/40 R 18 tyres are used at the rear. 19-inch M light alloy wheels in two designs and 19-inch BMW Individual light alloy wheels, likewise fitted with mixed tyres, are also available as an option. The 19-inch M light alloy wheels come with high-performance tyres facilitating a particularly effective transfer of longitudinal and lateral forces.

Design and equipment features with a clear emphasis on sportiness. 
The new BMW M340i xDrive Sedan’s superior performance characteristics are reflected in model-specific design and equipment features. The design of the front apron, the side sills and the rear end, optimise both the cooling air supply and aerodynamics. Unique design elements include the BMW kidney grille boasting a mesh design, the rear spoiler in body colour and trapezoidal exhaust tailpipe trims. The vehicle’s exclusive look is also complemented by exterior mirror caps, air intake struts, the front surfaces of the BMW kidney grille, tailpipe trims and the model lettering all finished in Cerium Grey metallic.

Inside the car, sports seats with M-specific upholstery in a Sensatec/Alcantara trim, the anthracite BMW Individual roof liner, the M leather-clad steering wheel with shift paddles and interior trim strips in Aluminium Tetragon provide for an intensive driving pleasure oriented ambience. The digital instrument cluster bears the lettering “M340i”. A further exclusive design feature of the BMW M340i xDrive Sedan are the front door sills also boasting the model lettering.
