BMW is bringing several interesting models at the NAIAS 2013 in Detroit. The manufacturer will exhibit the new Concept 4-Series Coupe (F32), M6 Gran Coupe, Z4 Roadster, 1-Series Coupe and 1-Series Convertible Limited Edition Lifestyle.

The 4-Series Coupe is one of the most interesting new BMWs. Until now, the manufacturer didn't have 4-Series in their line-up. The new vehicle is bly larger than the BMW 3 Series Coupe in terms of length, width and wheelbase, while the roofline is considerably lower. The car is much more aggressive at the front and at the rear. The new BMW Coupe embodies a development curve at its zenith.

The alluring interior exudes cutting-edge luxury, with elaborate details and exquisite materials sharing centre stage.

Here again, the BMW Concept 4 Series Coupe reveals a spectrum of qualities set amid new dimensions and underlines the brand's ambitions through its unrelenting pursuit of perfection.

The high-performance M6 Gran Coupe brings together the hallmark performance attributes of M cars within a handsome and sumptuous design. The extra room on board the four-door Coupe allows two rear passengers to bask in generous levels of spaciousness.

It is powered by the a 4.4-liter twin-turbo V8 with 560PS (412 kW) and 680Nm (502 lb-ft). It is mated to a 7-speed M Double Clutch Transmission. 0 to 100 km/h in 4.4 seconds, 0 to 200 km/h in 13 seconds and top speed of 250 km/h (155 mph) electronically limited and 305 km/h (190 mph) with M Driver's Package.

The Z4 Roadster is now available with three new body colours are available exclusively with the Design Pure Traction option, which is also new. Meanwhile, black and orange tones create a particularly absorbing contrast of colours in the interior.

There are also new 17" and 18" light-alloy wheels and the optional M Sport package. And there is also the arrival of a new model variant to report; the BMW Z4 sDrive18i is powered by a 2.0-litre engine with BMW TwinPower Turbo technology developing 156 HP (115 kW).

This new entry point to the Z4 range can also be ordered with an eight-speed automatic gearbox.

The selection of driver assistance systems and BMW ConnectedDrive mobility services available on board the BMW Z4 has also been expanded. If the Professional navigation system is specified, the ConnectedDrive Services option enables use of internet-based information and entertainment services inside the car.

Both 1-Series Coupe and 1-Series Convertible are available with Limited Edition Lifestyle equipment package.

As well as the exclusive Mineral White metallic paint, customers can also choose from two other exterior colours, while 18" light-alloy wheels accentuate the cars' classy looks.

The Lifestyle Edition contrasts are particularly effective on the BMW 1-Series Convertible; a brown soft-top with silver pigmentation generates fascinating light effects, for example. Brown leather trim with white contrast stitching plays the lead role in the interior of the Lifestyle Edition cars.

A matching brown sports leather steering wheel, specially badged door sill strips and Fineline Stream fine wood trim elements add the finishing touches to the interior ambience.
