BMW AG’s 2017 M550d midsize performance model will be powered by the company’s new quad-turbo 3.0-liter straight-six diesel engine.

The engine generates 400 hp and 560 lb-ft of torque, which the carmaker says makes it the most powerful 6-cylinder diesel in the industry. Mated with an 8-speed automatic transmission, the engine allows the car to sprint from zero to 62 mph in 4.4 seconds.

The quad-diesel teams two low-pressure turbochargers for low-end torque with a pair of high pressure units to handle the rest of the rev range. The previous generation engine had a tri-turbo design with two high-pressure units and a larger low-pressure turbo.

BMW says the fourth turbocharger optimizes the engine’s efficiency and performance characteristics. The new M550d sedan emits 154 g/km and has fuel efficiency rating of 40 mpg based on the European driving cycle.

The new M550d, which also is available as a wagon (pictured), has a rear-biased all-wheel-drive system. Other goodies include a sport suspension and brakes, active steering and an M aerodynamics package.

    As Nature (yes, capital N Nature) has done a pretty good job of designing things, it is somewhat surprising that Man (ditto) doesn’t follow Nature’s lead more often when it comes to designing objects.

  • Mustang Changes for 2018

    On Tuesday Ford unveiled—using the social media channels of actor Dwayne Johnson (this has got to unnerve some of the auto buff book editors)—the 2018 Mustang, which has undergone some modifications: under the hood (the 3.7-liter V6 is giving way to a 2.3-liter EcoBoost four, and a 10-speed automatic is available), on the dash (a 12-inch, all-digital LCD screen is available for the dashboard), at the tires (12 wheel choices), on the chassis (MagneRide damper technology is being offered with the Mustang Performance Package), and on the exterior (three new paint colors). And while on the subject of the exterior, there are some notable changes—a lower, remodeled hood, repositioned hood vents, new upper and lower front grilles, LED front lights, revised LED taillamps, new rear bumper and fascia.
