2011 Bmw 7 Series 750i Xdrive Performance Review
What Is Information technology?
Something like an M7, if 1 were to exist. Like an 1000 motorcar, the Alpina-tuned B7 isn't solely focused on increasing ability—as BMW does within the 7-series lineup in moving from the V-8 750 to the 5-12 760—instead delivering a rich mix of cosseting luxury, rocket-send thrust, and fifty-fifty-more-athletic handling. And now the B7 is available with xDrive all-wheel drive.
In the case of our examination automobile, the transformation began with a short-wheelbase 750i xDrive. (Rear-drive and long-wheelbase 750s also can become B7s.) Under the hood, the twin-turbocharged 4.4-liter V-viii is massaged to produce 500 hp and 516 lb-ft of torque, 100 more hp and 66 more than lb-ft than in a run-of-the-mill 750. Those considerable numbers are achieved using bigger and boostier (14.5 psi) turbos, larger intercoolers, high-performance pistons, stronger cylinder heads, and a uniquely tuned ECU. Alpina so enhances temperature direction by adding an engine-oil cooler, a transmission libation for the beefed-up six-speed automatic, and a larger radiator. The driveshaft, the half-shafts, and the differential housing are also upgraded to handle the increased twist.
The upfitting continues with the break. The springs are stiffened by about 20 per centum, and the Alpina sits lower than an equivalent 7er by 0.6 inch in forepart and 0.4 inch in the rear. The B7 also gets its own traction- and stability-control programming.
Adjacent comes the makeup, starting with Alpina's gorgeous twenty-spoke, 21-inch wheels. If y'all tin can persuade your optics to motility on from the rolling stock, y'all'll find a unique front fascia, a torso-mounted spoiler, and special frazzle finishers resting below a new rear valance. Inside, at that place are handsome bluish-faced gauges, an Alpina-specific steering wheel with gearshift buttons on the back, cushy-soft nappa leather upholstery, a numbered Alpina plaque on the overhead console, and Alpina logos scattered throughout.
How Does It Drive?
You might recollect a 4886-pound luxury liner riding on a set of wagon wheels would exist as stiff every bit a stagecoach—and turn like 1, too. But the B7 actually hits the sweetness spot, offering a luxurious ride and nearly trackworthy treatment, no matter which of the four chassis settings you cull. It'due south obviously a bit cushier in comfort mode and tighter in the sport and sport-plus modes—where a touchier throttle, more aggressive gearbox programming, and weightier steering liven things upward—simply information technology never gets wallowy or overly harsh. The no-compromises chassis combines with BMW'due south fantabulous xDrive AWD system to evangelize a performance-and-luxury auto perfect for whatever weather and all occasions. The xDrive system functions every bit it does in the 7-series xDrive and v-series xDrive models, only it's said to take been retuned for Alpina duty due to the B7's output increase. It works well. When we tossed this bruiser into a corner, initial understeer was speedily mitigated by the system's shifting torque rearward, keeping us on our intended path.
How Does Information technology Stack Up?
It fared almost identically to the rear-bulldoze B7 at the examination rails. The xDrive model totes an boosted 176 pounds, but its extra traction off the line helped information technology match the RWD model's 4.3-second 60-mph and 12.8-second quarter-mile times. Information technology was 2 mph slower at the trap, still recording a apparent 111 mph. Braking was once more remarkable for such a large automobile, tallying 163 anxiety from lxx mph, one foot longer than the rear-drive B7. The xDrive, every bit you lot might expect, clung to the skidpad with a scrap more tenacity, riding the same Michelin Airplane pilot Sport PS2 safe to 0.88 g, an increase of 0.03.
What'south the Toll?
Nosotros had two complaints about this B7. We'd like a niggling more growl from the exhaust, and we tin't afford to purchase one. The B7 xDrive's premium over its short-wheelbase rear-drive sibling is $3000, so information technology starts at $127,175, including a $1300 gas-guzzler revenue enhancement. Our test vehicle packed on about 10 thou in options, including a rear-and-side-view camera parcel ($1200); a Driver Aid bundle that nabs auto high-beams, lane-departure alarm, and blind-spot detection ($1350); a rear entertainment setup ($2200); an annoying active cruise-command system ($2400); and night vision ($2600), amidst a few other bits. We'd definitely skip the active cruise and probably leave out nighttime vision, too.
If the planets aligned, the moo-cow jumped over the moon, and we won the lottery, this Alpina B7 would be among our top picks to make full the big-ticket luxury-sled slot in our garage. Dorsum in reality, we had to give this one dorsum—simply non before picking up a few Powerball tickets for good measure.
