Edmunds.com takes the new 2013 BMW 650i Gran Coupe to the race track to test the sportiness of BMW’s first four-door coupe.

The 4.4-liter V-8 engine (N63) that powers the current 650i models received an upgrade for the new 650i Gran Coupe. This new version of the engine adds BMW’s VALVETRONIC variable valve timing to the list of specifications. As a result, the new version of the engine (N63Tü) develops a maximum 445 hp between 5,500 and 6,000 rpm (a 45 hp increase), and makes peak torque of 480 lb-ft between 2,000 and 4,500 rpm (a 30 lbs-ft increase).

Official specs say that the new BMW 650i Gran Coupe completes the sprint from 0 to 62 mph (0 to 100km/h) in 4.6 seconds but let’s find out what Edmunds says in their own review.

 

Test Results:

Acceleration
0-30 (sec): 2.3 (2.7 w/ TC on)
0-45 (sec): 3.6 (4.1 w/ TC on)
0-60 (sec): 5.2 (5.8 w/ TC on)
0-60 with 1-ft Rollout (sec): 4.8 (5.3 w/ TC on)
0-75 (sec): 7.0 (7.6 w/ TC on)
1/4-Mile (sec @ mph): 13.1 @ 109.4 (13.5 @ 108.7 w/ TC on)

Braking 
30-0 (ft): 29
60-0 (ft): 114

Handling
Slalom (mph): 66.3 (65.2 w/TC on)
Skid Pad Lateral Acceleration (g): 0.88 (0.85 w/TC on)

Db @ Idle: 40.0
Db @ Full Throttle: 71.1
Db @ 70-mph Cruise: 60.0

RPM @ 70: 1,650

Acceleration: Default mode (Comf/Drive) hesitates slightly from a dead stop. Each successive mode makes the car slightly quicker (Sport, Sport+ and DS) but launch delay persists regardless. The time gap between slowest and fastest 0-60 is significant, about a half-second in total. The traction control is effective, but it has a short leash. Once underway, the power builds quickly and carries all the way to the 7,000-rpm redline. I “beat” traction control with a two-footed non-wheelspin launch with Trac off. There’s ample cooling as trap speeds remained steady. Upshifts are both fast and smooth, as are matched-rev downshifts. In manual mode, it will allow the engine to bounce off the rev limiter.
