Driving
I'd feel a bit bad for the driver on that trip, though. While the 400-horsepower, turbocharged 4.4-liter V-8 engine is relatively sprightly in the 750i, I thought it was a bit of a laggard while towing all the additional weight that comes with the 750Li's longer wheelbase and xDrive all-wheel-drive system hardware. All of the driving comfort Mike Hanley mentioned in his review of the 2009 750i is still there, but I found the experience a bit numbing. That may be good for some large luxury sedans, but probably not ones adorned with the letters B, M and W.
The front seats are nearly as comfortable as the rear ones, but the massage feature works just your thighs — and buttocks, I must add — to keep the driver alert.
It's not a pleasant sensation.
