The 2013 BMW 6-Series models are quiet, comfortable grand tourers, and even though they offer up surprisingly strong performance, comfort and quiet--as well as a tight, well-appointed cabin--are top priorities.
Last year BMW replaced the previous 6-Series' somewhat clunky space with a well-built and intriguingly designed cabin. The driver-focused controls sees the center console canted toward the left, and the control surfaces are made of plastics and leathers that look and feel premium. The overall effect from inside is one of classiness and exuberance.
If you're taller, you might need to tuck your head a bit when getting in and out, but once you're inside that lowish roofline is no longer an issue in the Coupe. The front seats offer great back and thigh support, as in most of their lineup, while there should be enough headroom for nearly everyone. Thanks to a plethora of adjustments and comfort-enhancers in the front powered buckets, there should be no problem finding a supportive.
BMW gave the 6-Series a stretch with last year's redesign, but in either Coupe or Convertible models there's still just not enough space for adults back there. Even with the front seats scooted up for shorter folk in front, those back seats are best left for kids or cargo.
Gran Coupe models feature four doors and what BMW calls 4+1 seating, making egress into the rear seats easier than 6-Series Coupe models. The Gran Coupe retains the driving dynamics of the standard Coupe, but its improved rear accommodations (with a wheelbase that's 4.5 inches longer and virtually all of that going to rear legroom) make it more appealing to those who regularly carry more than one passenger. That said, the Gran Coupe isn't a substitute for the 7-Series, or any of BMW's more upright sedans, really, as while legroom is okay there's still not enough headroom for most adults. For parents or grandparents who want the feel of a coupe but with a few extra seats for the weekend, it's perfect.
Even though the BMW 6-Series sticks with a fabric top in Convertible form. While rivals have gone all-in on folding hardtops, BMW's fabric roof is a better choice for convenience and for packaging, not to mention weight savings. In under 20 seconds, the fabric roof can be stowed or raised, and it fits in a smaller space than most folding hardtops. Its glass window can be opened for better ventilation, too. With the top down, the trunk has 10.6 cubic feet of space.
