BMW recently introduced the newest update to their 5 Series line, the 2012 BMW 528i. The most distinct and controversial change is replacing the beloved free-aspirated 6-cylinder engine with new turbocharged 4-cylinder technology.

Skeptics immediately associated a smaller engine in a larger car with poor performance. However, forced induction in the new engine produces the same horsepower as the old free-breathing 6 cylinder engine. The 4-cylinder generates 240 hp and 260 lb-ft of torque, 30 more lb-ft of torque that comes on 1500 RPM lower. With the 8-speed automatic transmission, the 4-cylinder 528i accelerates to 60 mph in 5.9 seconds, 0.4 second quicker than a 2011 6-cylinder 528i.

Fuel economy for the new engine is reported to be 23 mpg city and 34 mpg highway, 1 mpg more city and 2 mpg more highway than the 2011 model, though the EPA has yet to issue an official rating. An Eco mode of driving adjusts the engine map, heating, air-conditioning and mirror/seat heating to reduce fuel usage. To further stretch fuel economy, the 2012 BMW 528i features Auto Start/Stop. This function turns the engine off when the car is stationary or in slow traffic.

The 2012 528i is available in conventional rear wheel drive or xDrive All Wheel drive. xDrive Dynamic Driving Control that offers different presets that can modify the throttle response, automatic transmission shift points, suspension damping and stability assist.

Aside from the new engine, the 528i is also fully equipped with all quality standard features and luxury options BMW drivers have come to expect.
