BMWBlog took the 2013 BMW 750Li xDrive and called is as an 'Ultimate Luxury Machine' because of the gadgetry and range of technology included in this vehicle. After spending 1 week using the vehicle, here is an excerpt of their review.

So how does it sound? Nothing short of amazing, crystal clear high notes, and an exceptionally natural sound from 16 speakers distributed around the cabin. The two bass speakers, seven mid-range speakers and seven tweeters all have individual amplifiers, creating an Active Sound system. The total watts output is 1200.

As you would expect in a 7 Series, and especially in a long-wheelbase model, the legroom for rear-seated passengers is more than one can ask for. Even at 6″2 or roughly 1.88 meters, I was able to comfortably stretch my legs. The massaging and ventilated seats just simply point to high-end luxury cleverly packaged in the flagship bimmer.

On the safety front, the 2013 BMW 750Li xDrive is full of airbags including front-seat-mounted side-impact airbags, side curtain airbags for both rows, and knee airbags.

Yet Still An Ultimate Driving Machine

Four years later and the BMW 7 Series continues to impresses us. The 2013 BMW 750Li xDrive provides exemplary handling matched with an adjustable ride quality that satisfies a wide range of customers. Thanks to the new adjustable Dynamic Damper Control that works together with the Driving Dynamics Control, the tailored driving experience is sublime. The driver can select between the Sport, Sport+, Comfort, Comfort+ and new for 2013 models, ECO PRO with Coasting Mode which can reduce consumption by up to 20%.

Over the course of nearly 1000 miles, we have equally tested all the driving modes to get a feel for what the car can do in different situations. As expected, the Comfort and Comfort+ modes are geared towards those looking for a smoother, calmer ride or simply for cruising. In the negatively famous Chicago traffic and roads, we found those two driving modes to be ideal while MPG rates were kept in check.

Now switching over to Sport or Sport+ the 2013 BMW 750Li xDrive transforms itself. The throttle is sharper, suspensions are more loaded and RPMs were raised a bit, all of those setting up the car for spirited driving. In Sport+ especially the 750Li xDrive is very agile despite its 4800 lbs curb weight.

The power delivery is robust and eloquent making the 750Li xDrive a large luxury sedan that enjoy being pushed around.

All this performance is possible thanks to the updated 4.4 liter V8 TwinTurbo engine which now had Valvetronic added – BMW’s throttles intake system – resulting in additional 45 horsepower and 35 lb-ft torque to a total of 443 hp and 479 lb-ft. The shorter exhaust path to the turbochargers is one of the reasons for the significant power upgrade.

0 to 60 comes in a staggering 4.6 seconds, just a tenth of a second slower than the 6.0 liter V12 760Li.

Compared to the pre-facelift models, the new 2013 BMW 750Li xDrive has improved its fuel consumption by 15%, in our test that translated into 19MPG combined.

Our test car also came equipped with the Active Damper Control and Active Roll Stabilization which help reducing body roll in high-speed corners by measuring lateral acceleration and uses hydraulic actuators to stiffen the antiroll bars.
