KBB Expert Review

KBB Editors' Overview

By Keith Buglewicz - Updated Date: 5/27/2014

The 2015 BMW 6 Series slots between the 5 and 7 Series cars with a coupe, a convertible, and a 4-door that BMW calls a "Gran Coupe," but we all know is really just a sleek sedan. Sleekness is all part of the game though, as the 6 Series is designed to offer eye-catching style over practical transportation. All three models offer plenty of style and performance, with engines ranging from a turbocharged 6-cylinder to a couple different V8 models. With roots that trace back to the late 1970s, the 3rd-generation 6 Series remains a leader in grand touring, even against such tough competitors as the Jaguar XK, Mercedes-Benz E-Class Coupe and Audi S5.

You'll Like This Car If...

With prodigious power, advanced technology, and luxurious surroundings, the 2015 BMW 6 Series offers a surprising value compared to competition like the Jaguar XK and Mercedes-Benz E-Class Coupe.

You May Not Like This Car If...

Of course, "value" is relative, as the base price of a BMW 6 Series is more than $75,000. If that's too dear for you, the Audi S5 offers a quick package at a considerably lower price. BMW's own 4 Series coupe does the same, and keeps that coveted badge.

What's New for 2015

The new 2015 BMW Alpina B6 xDrive Gran Coupe offers more performance than the 650i xDrive, but more luxury than the M6 Gran Coupe. Alpina, by the way, is a 3rd-party high-performance BMW tuner, working so closely with BMW that its cars are sold in BMW dealerships.

Driving It Driving Impressions

The 2015 BMW Alpina B6 xDrive Gran Coupe offers a unique experience in the BMW 6 Series range. With power close to what you get in the all-conquering M6 model, but with a bespoke interior treatment unavailable in any other model, the B6 offers tremendous performance and luxury in one package. It's as if the B6 magnifies everything we already like about the BMW 6 Series: There's the luxury, which – across the lineup from coupe to convertible to Gran Coupe sedan – means quiet and comfortable cruising suitable for mile after mile of open-road touring. Yet when the Driving Dynamics Control is in Sport+ mode, the 6 Series transmission kicks down eagerly and the suspension tightens, transforming this big car into a surprisingly nimble sporty car. Even the "base" 640i Coupe leaps to 60 mph in just over five seconds, and the M6 does it in just over four.

Favorite Features

While the BMW 6 Series is referred to as a family of coupes, the reality is that the Gran Coupe is actually a sleek 4-door sedan. That it means the goodness of the 6 Series is open to anybody who wants it, even if you can't give up 4-door practicality.

The name may sound odd to those who aren't audiophiles, but listen to this optional sound system and you'll soon join their ranks. This primo audio option drenches ears with 1,200 watts of sound emanating from 16 speakers, each with its own amplifier.
