The 2016 BMW 7 Series May Have as Many Turbos as a Bugatti Veyron
In efforts to shore up its offerings on the high side of the sedan spectrum, BMW is pulling out most — if not all — of the stops for its new 7 Series. It’s already one of the most technologically advanced vehicles available to the general public, but Bimmer seems keen on bringing that school of thought under the hood as well. If a report by AutoCar is to be trusted, the new 7 Series will be packing as many turbos as a Bugatti Veyron. In case you’ve forgotten, that’s four.
That, according to AutoCar, will be the drivetrain powering a new trim level, the M750d. It would bump out BMW’s existing tri-turbo diesel engine, and supposedly sport displacement of 3.0 liters and produce “well over” 400 horsepower and 590 pound-feet of torque. It’s notable that American never got the tri-turbo diesel 7 Series, and it’s unclear — if not unlikely — that we’ll get the one with a quartet of turbochargers.
But that doesn’t trivialize the incredible engineering that an engine of this magnitude represents. While three of the turbos could operate in the conventional fashion — that is, powered by exhaust gases — the fourth would spool up by means of electric power, limiting spooling time and improving engine response. Noting the speculative nature of the report, AutoCar hedged its statements by adding that “Alternatively, BMW could improve induction qualities by using a fourth conventional gas-driven turbocharger.”
The engine will also supposedly be tapped for the high-end X5 M diesel and X6 M diesel, neither of which we get here in the States.
If all this turns out to be true, it would represent BMW’s extreme commitment to forced induction as a means to boost power whilst simultaneously maintaining regulation-worthy fuel economy. Turbos also help produce sizable lumps of torque, a crucial factor involved in moving a land boat such as the 7 Series. However, with the added complexity comes added risk of failure or higher maintenance costs.
The new car, which internally is known as the G11, “is built on the new 35up platform, which will underpin every sedan in the BMW lineup from the 3-Series up,” we wrote. “It’s also the first mass market car to utilize carbon fiber reinforced plastic structural elements, helping the car shed nearly 300 pounds while growing an inch over the outgoing model. Inside, it’s the first production vehicle to offer gesture control to for the infotainment system, along with “Remote Control Parking,” a feature that BMW says allows the car to ‘manoeuvre (sic) itself in and out of the garage or a parking lot, without the driver behind the wheel.'”
Inside and out, it seems that BMW is seriously committed to making the new 7 Series the most advanced luxury car on the market. While Mercedes’ S-Class is still the standard-bearer of the executive sedan segment, BMW’s effortless blending of tech and luxury may make it hard for uncommitted buyers to ignore. And with the potential of a quad-turbo setup, BMW may be slaying the “no replacement for displacement” dinosaur once and for all, and bringing supercar tech almost within reach.
