As promised, BMW is continuing to expand the application of its mileage-maxing EfficientDynamics technologies throughout its product line. The latest model to benefit is the 2012 BMW 528i. When it goes on sale this fall, the entry level member of the 5 Series family will see its existing 3.0-liter inline-six engine replaced by the firm’s new 2.0-liter TwinPower Turbo four-cylinder, a change destined to enhance performance on all levels. The 2012 528i also will arrive with BMW’s xDrive intelligent all-wheel-drive system as part of its option list.
Heart of the 2012 528i, the 2.0-liter TwinPower Turbo four is a techno wonder that matches direct fuel injection and BMW’s Valvetronic throttle-less variable intake valve lift control with a single, twin-scroll turbocharger and an intercooler. Lighter and more compact than the outgoing 3.0-liter six, it makes an identical 240 horsepower, but does so at just 5,000 rpm -- 1,500 revs lower in the range. The turbo 2.0-liter holds an even more tangible edge in the torque department, making 260 pound-feet of peak twist -- a 30-percent bump -- and reaches it at just 1,250 rpm, also 1,500 revs lower than the six. BMW says the new engine will permit the 2012 528i to sprint from 0-60 mph in 6.2 seconds, making it 0.4 second quicker to the speed than the 2011 model.
To take fullest advantage of the capabilities of this new TwinPower four, BMW is complementing it with a host of other econo-boosting elements, starting with an eight-speed automatic transmission. The 2012 BMW 528i also will feature Auto Start/Stop, ECO PRO that modifies engine mapping, cabin heat/air-conditioning and mirror/seat heating to enhance fuel economy plus Brake Energy Regeneration that decouples the alternator unless the car is braking, coasting or decelerating. Although the EPA has yet to publish official mileage figures for the car, BMW says it expects the 2012 528i’s figures to improve about 15 percent over the 2011’s 22/32 mpg numbers.
Buyers seeking the ultimate in all-season/all-surface grip will be able to order their 2012 BMW 528i with a custom-tuned version of the automaker’s xDrive intelligent all-wheel drive system. Coupled with BMW’s Integrated Chassis Management (ICM) that can instantly shift torque rearward as well as mete out the optimum left/right split, it significantly raises the car’s stability index and helps maintain neutral handling under virtually all conditions.
