Variety, thy name is 5 Series. With the 2012 introduction of a new 4-cylinder turbo, BMW offers a “holy trinity” of powertrains. And that which is the most compelling, the 2.0-liter four is also the least expensive. It delivers 240 horsepower, 260 lb-ft of torque and 32 mpg in the EPA’s highway cycle. In short, what’s not to like? Perhaps the lack of an available manual transmission with the turbo four, but that absence can’t last forever; the rumble for its return starts right now. The turbocharged inline-six has, of course, its fans, while the 4.0-liter turbo V8 seems – in a still-funky economy – a tad too much.
