3.0L Turbodiesel DOHC I-6 (BMW 535d)
It could be argued that 2013 was the year of the diesel, as more automakers offered the low-reving oil-burners this year. Savvy automakers like BMW used the fuel to juice up their model lineups with better fuel efficiency, without ruining the fun factor. The 3.0-liter turbodiesel found in the 535d as well as the X5 uses a single turbocharger to deliver peak torque of 413 lb-ft as soon as 1,500 rpm. Without a doubt, BMW’s diesel delivers the twist, but also manages to be fuel friendly and quiet, hence it’s place on this top 10.
