Still hoping the US will get RWD and all the model lines including the Modern Line according to the official press release - nothing mentioned about xdrive or xdrive only. Perhaps it will show up on the BMWNA website this week?

The All-New BMW 3 Series Gran Turismo.
Innovative vehicle concept comes to the 3 Series Line-up.
Woodcliff Lake, N.J. – February 6, 2013 . . . The all-new BMW 3 Series Gran Turismo adds an innovative new concept to the BMW 3 Series lineup. The BMW 3 Series Gran Turismo is, first and foremost, a driver’s car which combines the dynamics that have earned the new 3 Series a spot on “Car and Driver’s” 10Best list for 22nd consecutive years, with luxury seating for four and generous and flexible luggage capacity. The new BMW 3 Series Gran Turismo will arrive in the US, as both a 328i and a 335i, in the summer of 2013 as a 2014 model.
Three equipment lines, each with their own individual character and M Sport
High-quality material combinations coupled with class-leading levels of workmanship reinforce the premium ambience on board the new BMW 3 Series Gran Turismo. A large number of color and upholstery variants offer scope for a multitude of combinations. Customers can also choose from three additional equipment plus M Sport, all of which add individual touches to the car’s looks inside and out. Indeed, even the ignition key shares the color-coding of the equipment line specified.

Sport Line: The Sport Line adds extra depth to the dynamic repertoire of the BMW 3 Series Gran Turismo with a selection of eye-catching exterior features in high-gloss black. Nine molded black kidney grille slats in a chrome-colored surround lend the front end a particularly sporty and alert look, and the forward-slanting angle of the BMW kidneys gains further visual impact. The black air intakes and likewise gleaming black Air Breathers, meanwhile, draw the eye to the car’s aerodynamics features. Optional 18-inch or 19-inch light-alloy wheels – depending on the model – in double-spoke design provide an additional dose of sportiness, while exterior mirrors and a “wraparound” window strip, B-pillars in matching paint finish and a trim strip at rear apron height add further flourishes. Inside the car, the contrast between black and red accents adds a sporty and exclusive allure that is heightened by the accent strips in the doors (also part of the Luxury and Modern Lines as well as M Sport). The standard sports seats can be specified with a choice of upholstery and colors.

Luxury Line: Discreet high-gloss chrome touches lend the exterior of the BMW 3 Series Gran Turismo a particularly elegant and exclusive appeal. 11 intricate kidney grille slats with chrome-colored fronts and matt black sides, two chrome blades in the front apron air intakes and chrome Air Breathers all furnish classy touches. Within the gleaming chrome window surround, the black B-pillar provides a particular highlight, and special 18 and 19-inch light-alloy wheels in a multi-spoke design accentuate the elegance of the Luxury Line. The Gran Turismo Luxury Line can be identified from the rear by a stylish, high-gloss chrome strip above the rear apron and a chrome exhaust tailpipe embellisher. The interior also stands out with various chrome elements, such as the surround for the audio and air conditioning system. High-gloss wood strips and seats with distinctive stitching highlight the exclusivity of the Luxury Line.

Modern Line: High-quality chrome exterior trim elements define the cool aesthetic of the Modern Line, while the BMW kidney grille with 11 slats, the Air Breathers and the double trim strips for the air intakes continue the theme. 18 or 19-inch turbine-style light-alloy wheels lend a fresh angle to the exterior design of the BMW 3 Series Gran Turismo, while the light-colored dashboard coupled with a steering wheel in dark oyster create a very special ambience in the cockpit. Leather upholstery in oyster or black, and a choice of three trim surfaces with accent strips in pearl-effect chrome, ensure an appealing interplay between materials.
M Sport: Optional M Sport line gives the new BMW 3 Series Gran Turismo a shot of adrenaline that spreads beyond its exterior and interior design. As well as the all-new aerodynamic package, including numerous body components (front apron with large air intake, rear bumper with diffuser, side skirts), and the BMW Individual High-gloss Shadow Line trim, the optional exterior color Estoril Blue metallic ensures an unmistakably sporty appearance and unbeatable road presence – an effect underpinned by 18 or 19-inch light-alloy wheels in hallmark M design. Inside the car, features such as M door sill finishers, an M leather steering wheel and an M driver’s footrest shape the sporty yet elegance ambience. The driver and front passenger can settle into sports seats. Technical features of this package include lowered M Sport suspension and enhanced aerodynamics.

Customers can choose from a total of 12 paint finishes, irrespective of the equipment line specified, including intense color shades, an array of metallic options and a broad spread of classic tones. The Kalahari Beige metallic, Midnight Blue metallic and Sparkling Brown metallic shades are reserved exclusively for the new BMW 3 Series Gran Turismo.

BMW 328i Gran Turismo: 4-cylinder gasoline engine with TwinPower Turbo technology sets the benchmark for dynamics and efficiency
The state-of-the-art, lively 2.0-litre engine marks a return to the 3 Series roots – it was with lightweight, high-performance 4-cylinder engines in a similar vein that the BMW 3 Series made its debut back in 1975. The significant upgrade in power and efficiency
is chiefly down to the use of BMW TwinPower Turbo technology, which combines High Precision Direct Gas Injection, Double-Vanos variable camshaft timing and Valvetronic variable valve timing along with twin-scroll turbocharging. On the new-generation 4-cylinder engine, this world-exclusive technology package from BMW again provides a very efficient way to extract more power from the engine, rather than taking the route of a much larger displacement and, in the process, adding to the weight and therefore to fuel consumption. This explains why the more dynamic performance and driving enjoyment does not come at the expense of higher fuel consumption and emissions.
The new BMW TwinPower Turbo 4-cylinder’s displacement of 1,997 cc delivers maximum power of 180 kW/240 hp at 5,000 rpm while, thanks to twin-scroll turbocharging, the maximum torque of 255 lb-ft is developed at just 1,250 rpm and remains constant up to 4,800 rpm. These statistics translate to commensurately dynamic performance. The engine responds instantly when the driver demands more throttle, and the vigorous and almost linear power delivery from only slightly above idle, which continues all the way into the higher rpm range, is duly impressive.

This new engine is the most powerful in a new generation of 4-cylinder engines designed in accordance with the BMW EfficientDynamics strategy, which aims to combine increased driving enjoyment with reduced fuel consumption and emissions.

BMW 335i Gran Turismo: Inline 6-cylinder engine with beefy power delivery, strong torque and superb refinement
Fans of large 6-cylinder engines have a treat in store too. The inline 6-cylinder engine (N55) in the BMW 335i Gran Turismo will impress performance-minded drivers with its effortless power, exceptionally fast-revving temperament and outstanding refinement. The N55 has been setting standards from the start, as the pioneer of a new generation of engines in which BMW TwinPower Turbo technology with High Precision Direct Injection and Valvetronic variable valve timing plus a twin scroll turbo made its debut.
Thanks to intensive fine-tuning of the engine, BMW’s engineers have now further reduced the fuel consumption and emissions of the predecessor, while at the same time maintaining its high performance. With a maximum power rating of 225 kW/ 300 hp at 5,800 rpm, the 3.0-liter 6-cylinder unit reflects the sporty personality of the BMW 3 Series and helps deliver brilliant performance. And the high peak torque of 300 lb-ft, on stream between 1,200 and 5,000 rpm, ensures that the power is effortlessly and instantly delivered.

The all-new BMW 3 Series Gran Turismo will arrive in US showrooms in late 2013 as a 2014 model.
