Track Tested: 2010 Lexus LS 460 Sport vs. 2009 BMW 750i Sport


2010 Lexus LS 460 Sport vs. 2009 BMW 750i Sport

Edmunds.com tests hundreds of vehicles a year, but not every vehicle gets a full write-up. The numbers still tell a story, though, so we present "Track Tested." It's a quick rundown of all the data we collected at the track, along with comments direct from the test drivers. Enjoy.

Lexus is offering a Sport package on the 2010 Lexus LS 460, and with a price tag of $6,185 on that option group, there needs to be some substance in it. At first glance, it looks good. You get a retuned suspension with air springs (instead of the coil springs ordinarily standard on the short-wheelbase, rear-drive model) and 19-inch Dunlop summer tires. Behind the Sport package's forged alloy wheels, Brembo six-piston fixed front calipers are visible. Engine tuning doesn't change; the LS 460 Sport has the same 380-horsepower, 4.6-liter V8 as other LS sedans.

Other obvious visual cues associated with the Sport package treatment include the blacked-out grille and extended front spoiler and rocker panels. Inside, you'll find paddle shifters, a heated steering wheels and seats with extra lateral bolstering. Our LS 460 Sport test car also had the Luxury Value Edition ($2,780) and Comfort packages ($2,035).

This all sounds nice, but the real test for any luxury sedan with "Sport" appended to its name is to face the king among kings, the BMW 7 Series. We just so happen to have tested a 2009 BMW 750i with the Sport package (the same car we have in our long-term fleet, actually), so we've published their results side by side. Does the Lexus have what it takes to hang with the Bimmer through the slalom? You'll find out after the jump.

Handling Rating: Good
Db @ Idle: 39.2
Db @ Full Throttle: 65.3
Db @ 70 mph Cruise: 58.2

Acceleration Comments: Very little technique to improve acceleration times. Doesn't really respond to brake torque... just wood it and go. "ECT Power" mode does little to improve times, either. Shifts in "D" come at redline. Minimal wheelspin.

Braking Comments: Brake response feels somewhat isolated from pedal input. Distances, however, are respectable for this 4,500-pound machine.

Handling Comments: Skid pad: Remarkable balance and feedback at the limit. You can easily drive with throttle despite low limits and relatively slow responses. Slalom: Surprisingly, turning stability control off actually means "off." Not much to be gained in doing so in slalom, however. Rear loses grip first, and this is a big car to slide at 65 mph.

Handling Rating: Excellent
Db @ idle: 41.1
Db @ full throttle: 73.6
Db @ 70 mph cruise: 66.7

Acceleration Comments: Smooth, effortless acceleration. Even when trying to launch hard, the 750 eases out of the hole to 60 mph in 5.2 seconds. Long gearing with ultra-smooth engine makes acceleration deceptive.

Braking Comments: Turns out even a 4,600-pound BMW stops like a 3 Series. No drama, no fade. Just a solid, consistent pedal every stop.

Handling Comments: On the skid pad, it rotates around the nose on throttle. Impressive balance and communication for a car this large. Stability control has excellent calibration. This car shrinks around its driver in the slalom, and its electronic performance enhancers (powertrain and chassis) actually work despite confusing interface.
