The favorite wagon of enthusiasts, the all-new 3 Series Sports Wagon will again offer the flexibility and utility one would expect from a premium wagon combined with the driving dynamics of the quintessential sport sedan, the BMW 3 Series. The new BMW 3 Series Sports Wagon will launch in Europe later this year and is set to arrive in US showrooms in the Spring of 2013 with the award winning N20 4-cylinder TwinTurbo engine, 8-speed automatic transmission and the equipment lines shared with its recently introduced 328i sedan sibling.

The new 3 Series Sports Wagon is slightly larger than its predecessor, most notably its wider track (front + 37 mm/1.46 in., rear + 48 mm/1.85 in.). The car’s length (+ 97 mm/3.66 in.) and wheelbase (+ 50 mm/1.96 in.) also accentuate its sporting character. Inside, the new BMW 3 Series Sports Wagon, rear passengers will appreciate the noticeable increase in space made possible by the larger dimensions. These larger dimensions also pay dividends in utility with nearly ten percent more cargo volume both with the rear seats up and when folded.

The new 3 Series Sports Wagon will be the next model to offer BMW Lines as a way to tailor the car to individual tastes, just as with the Sedan, by choosing from a trio of trim and equipment variants – the Sport Line, Luxury Line and Modern Line. Each presents its own individual take on the character of the Sports wagon, with exclusive, high-quality trim and material combinations. For the enthusiast who wants to go beyond even the Sport Line, the M Sport Line will also be offered because it is, after all, a BMW 3 Series at its heart.

BMW 328i Sports Wagon: new 4-cylinder gasoline engine with TwinPower Turbo technology sets a new benchmark for driving dynamics and efficiency.
With the launch of the new sports wagon, an ultra-modern 4-cylinder engine makes its debut in a BMW sports wagon. In keeping with the dynamic overall theme of the new BMW sports sedan, this new-generation of turbocharged engines offers plenty of power and performance, responsive acceleration, powerful torque, a high rpm ceiling and low weight. The new 4-cylinder engine, provides noticeably livelier power for maximum driving enjoyment, also comes with lower fuel consumption than its predecessor.

The state-of-the-art, lively 2.0-litre engine marks a return to the popular sports wagon’s 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, with the first 6-cylinder engines for this series making their appearance at the 1977 Frankfurt Motor Show.

The significant upgrade in power and efficiency is chiefly down to the use of BMW TwinPower Turbo technology, which combines High Precision Direct Petrol 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 new BMW 328i accelerates from 0 to 100 km/h (62 mph) in just 6.0 seconds, on its way to an electronically governed top speed of 155 mph with Sport Line. 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.

BMW TwinPower Turbo technology in the new 4-cylinder engine.
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. In technical terms, this new 4-cylinder engine is modeled on the current multi-award-winning 6-cylinder inline engine with BMW TwinPower Turbo technology (N55), which is the benchmark in its class for dynamic power delivery and impressive efficiency. This world-exclusive technology combines High Precision Direct Petrol Injection, Double-Vanos variable camshaft timing and VALVETRONIC variable valve timing with twin-scroll turbocharging.

These features give the new BMW 328i the sort of power which with a naturally aspirated engine would require more cylinders and larger displacement. At the same time, with its all-aluminum crankcase, this engine is lighter and more compact than a 6-cylinder engine of equivalent power. This has obvious benefits for driving dynamics: the reduced load on the front axle gives this BMW sports wagon greater agility and further improved steering and cornering characteristics.

Twin-scroll turbocharging.
The new 4-cylinder engines also feature twin-scroll turbocharging. This means that the exhaust stream from cylinders 1 and 4, and the exhaust stream from cylinders 2 and 3, follow separate spiral-shaped paths to the turbine wheel. This reduces exhaust back-pressure at low engine rpm, allowing the energy of the exhaust gas pulses to be utilized as efficiently as possible. The result is instant throttle response and fast-revving performance which BMW drivers can instantly translate into driving pleasure.

VALVETRONIC, Double-Vanos and High Precision Direct Injection.
The combination of a high power output and a simultaneous reduction in emissions is achieved by VALVETRONIC variable valve timing and Double-Vanos variable camshaft timing. The latest generation of the VALVETRONIC system features a faster-acting, optimized stepper motor with integrated sensor. Seamlessly variable control of intake valve lift dispenses with the need for a throttle butterfly. Instead, the air mass is controlled inside the engine, resulting in faster response. At the same time, pumping losses have been reduced to a minimum.

The excellent efficiency is also down to the High Precision Direct Injection system. Centrally positioned between the valves, solenoid injectors precisely control the supply of fuel. The fuel is injected very close to the spark plug, with a maximum injection pressure of 200 bar (2900 psi), resulting in clean and homogeneous combustion. The cooling effect of the directly injected fuel also results in a higher compression ratio than on port injection engines, bringing further efficiency improvements.

I like it overall.

I don't care for wagons but this is the best-looking one on the road. Sport Line looks best on the sedan but for the wagon Modern Line wins.
