Motor Trend’s Jonny Lieberman gets behind the wheel of two of the finest long wheelbase luxury sedans – the 2013 BMW 750Li and the Jaguar XJL Supercharged – to see which one of them does justice to their $100,000 plus price tags.

First, Jonny heads to the track to see what kinds of numbers these large, premium sedans put down, then he sees how they both handle on the rough roads outside of Santa Barbara, before finally getting chauffeured in the back seat of the cars to examine their distinct approaches to high-end luxury.
We have recently tested both cars and our own review will follow up.
BMW 750i/Li received upgrades to their powertrain for 2013 model year. Those upgrades enhance performance while improving efficiency. The 4.4-liter TwinPower Turbo V8 has been updated with Valvetronic, BMW’s throttle-less intake system. It works in concert with High-Precision Direct Injection and twin turbochargers, nestled on top of the engine, to deliver 445 horsepower, a 45 hp increase over its predecessor, and 480 lb-ft of torque, an increase of 30 lb-ft. This newly updated engine is mated to BMW’s 8-speed Steptronic automatic. Together, this combination yields even greater performance with a 0-60 time of 4.7 seconds.
All members of the new XJ lineup share the same 5.0-liter V8, offered in naturally aspirated and supercharged versions. The supercharged versions make either 510 hp and 461 lb-ft of torque for the Supersport edition, while the Supercharged-badged car makes only 470 hp.
So which one takes the win?
Let’s have a look.
