Another Face Of The 7 Series
BMW 7 Series, for decades, is a member of an elite class of luxury executive sedans. This is a territory occupied mostly by Germans such as Mercedes S Class and Audi A8. Some non-German models like the Lexus LS play in the same league. In its sixth generation, this BMW offers the fine driving in style and in traditional sedan format.
The current model, launched in 2016 sets a benchmark in lightweight in particular. BMW engineers extensively used carbon-fiber-reinforced plastic (CFRP) in the structure of the passenger cell. They reduced the weight while increasing the torsion strength and bending stiffness of the passenger cell.
Engine And Powertrain
Instead of an 8 or even 12 cylinder engine as usual in this class, the 740Le comes with a 2.0L turbocharged four-cylinder paired with an electric motor. The powertrain is completed by an 8-speed automatic transmission.
The system delivers net 322 horsepower and 369 lb-ft, thus less than a conventional 7 Series.
One advantage of the plug-in hybrid version is the ability to travel up to 40 kilometers on electricity alone when fully charged. And we tested this range up to the limit reaching 34 km. This was mixed use at around 23 degrees and with a maximum of two people on board.
And on electric battery alone, the 740Le will attain a maximum speed of 140 km/h before requiring assistance from the gasoline engine.
Before we sit behind the steering wheel, Dan and I had a slight doubt about whether a 4-cylinder engine (even with an added e-motor) can be an option for BMW’s flagship sedan. Doubts disappeared as I hit the road. This big sedan accelerates smoothly and the transition from e-drive to gasoline kick-in is seamless. And in a country where the effective speed limit is 119 km/h, this “green car” can easily keep pace with others.
As per BMW’s statement, the vehicle has a highly sophisticated, precision-honed chassis technology combined with 50:50 weight distribution. While driving, you can feel a sharp response and ride comfort. The double-wishbone front suspension, five-link rear suspension, and Electric Power Steering are three main components of the ride quality.
For the first time, carbon-fiber-reinforced plastic (CFRP) combined with steel and aluminium was used in the bosy structure of the new BMW 7 SEries with a completely new production processes aaplied in this unique mixed-material construction. The use of high-tech CFRP and advanced production methods enhance the torsional stiffness of the passenger cell and and lower the centre of gravity. All these features contribute to increased ride quality and comfort.
We would say perfect if one factor hadn’t blurred this picture: The tires: Pirelli Zero low profile, run-flat tires (275/30R/21) with 19″ M Double Spoke Wheels look great and very sporty. But there is a different story when the tires a pothole on the road surface. You feel like your bones are shaken in the well-insulated cabin. Such an expensive car deserves a much smoother hit and these tires are responsible. We think that BMW must do something about it the solutions seems to replace low-profile tires altogether.
I had two distinguished guests who experienced this comfort: Mr. Durmaz, a film produced and designer and Mr. Guldogan, film director, both from Turkey were our guests at the Ankara Library of Toronto for the showing of their documentary, “Şık Derviş” enjoyed the tide. I took them for a Niagara Itinerary from Toronto and they enjoyed the ride as front and rear seat passengers. Who wouldn’t love to be chauffeured in a car with extended wheelbase where backseat doubles as an office with fold out table, footrest and massaging function and you control everything via a dedicated Samsung tablet.
Our tester, which was equipped with Executive Lounge Tier 2 ($10,000) and Executive Package ($7,350) offers every imaginable luxury for a ride “in the sky”. Please see the spec sheet for a full list of options.
As we got back to Toronto after a long day and more 300 kilometers, our guests were happy and impressed with this driving experience.
Our average consumption in two days including Niagara was 9.2 liters. This is an impressive figure considering the size and weight of the car. Nevertheless, anybody who can afford a car with a base price of 118K, (our tester had an MSRP of $143,450), would not bother much about this consumption. However, this is testament that the high-tech hybrid system makes a difference.
This special BMW may be a good choice for executive class buyers, who value the luxury and prestige of the 7 Series while taking environmental concerns into account.
