REVIEWED: BMW 6 Series Gran Coupe

Here is an excerpt from the review:

The Gran Coupe’s double-wishbone front, multilink rear suspension uses aluminum for many of its structural components in order to reduce unsprung weight and quicken response. Shock damping is one of many parameters adjusted by the Driving Dynamics Control modes, as is roll stabilization and Active Steering (variable assist). Yes, active suspension, illegal in motorsports but wonderful here. It allows a relatively soft ride quality with minimal body roll in corners. The ride quality is never harsh, but there is a noticeable different between Comfort+ (think Euro luxury) and Sport+ (think Euro luxury performance). Interior noise levels are very low, as expected.

PERFORMANCE: How to reconcile performance and fuel economy: like many automakers, BMW is embracing turbocharging with direct fuel injection, automatic engine start-stop at lights, and brake energy regeneration. Direct injection allows higher engine compression, for both improved power and efficiency. Additionally, the N55 3.0-liter dual overhead cam inline six has VANOS stepless variable cam phasing on both cams and Valvetronic valve lift control to further improve power output and reduce emissions. The result is a smooth 315 horsepower at 6000 rpm, and more importantly for everyday driving, a healthy 330 lb-ft of torque between 1300 and 4500 rpm — meaning instant torque NOW. Add an eight-speed automatic with shift points and speed tied to the Driving Dynamics Control (DDC) system and both effortless high-economy (up to 30 mpg) highway cruising and quick acceleration are available. The best way to use the DDC system is to stay in EcoPro mode on the highway, with one of the Comfort modes for city driving and Sport or Sport+ for getting somewhere quickly. “D” usually works well, but even in Sport+ manual shifting is the way to go when the road gets really tight. With that wide torque band, shifting won’t often be necessary.
