Starting off in Comfort mode, we found the more relaxed setting on the throttle to be irritating. There was a fair amount of resistance to tip in on the throttle as we believe it’s meant to encourage efficient driving. The Comfort setting on the suspension also gave a floaty suspension that perhaps some like, but not our cup of tea.
Next up is the Sport setting which seemed to be just right, while Sport+ seemed a little to trigger happy, harder to modulate the throttle with out overdoing it. The steering had equal disparate sensations in the settings and I found Sport to be the best for my taste. The firmer dampening and less body roll in the Sport and Sport+ settings seemed more in keeping with the mission of this M6 Grand Coupe – namely kick some asphalt.
The hill country switch back roads were journalists’ dream come true: hair pin turns and massive rapid elevation changes. We were amongst a trio of M6 Gran Coupes that along the way formed a nice tight pack on a thankfully otherwise empty road. Some of the turns were so tight and involved such elevation changes that literally you could lose the road in the roof! We recall one section where a huge dip is combined with a very tight 90 degree right-hander followed by a rapid uphill. The nose of the M6 Gran Coupe was still pointed down as the road off to the right rose above the windshield. The eyes were trying to follow but instead of the road we were looking at the Alcantara headliner.
Then as the M6 hit the nader of the dip, you could see the continuation of the road. Crazy good stuff. The über tight roads allowed the M6 Gran Coupe to show off its incredible grip and balanced chassis control. Not once did we feel the car get unsettled, and just once we felt the understeer in a very slow turn. The 500 lb-ft torque which is available way down low at 1500 rpm pulled the M6 Gran Coupe out of these hairpins like a rocket ship and the active differential was working away to keep the rear-end planted when accelerating out of the hole.
As far as the civilized section goes where we hit some decent traffic, we came out impressed with the civil nature of such a powerful, grippy car. When just motoring along at the speed limit, the M6 Gran Coupe swaddles the occupants in incredibly luxurious cabin. The Head-Up Display is one of the best in the business and posting the speed limits in front of your eyes helped stay out of trouble with the local constable.
The M6 Gran Coupe is one of those cars that with a switch of a button can accommodate a wide range of customers and driving preferences. If the road is too bumpy, hit the Comfort mode, turn on your seat heaters while you have “chair conditioning” (seat cooling) on at the same time and crank your optional Bang & Olufsen stereo, and just ignore the rest of the world. Parting ways with the car at the end of this test was a little heartbreaking.
