The new BMW 7 Series hybrid is part of the recently unveiled new PHEV family which spans across multiple series – from the 3 all the way to the 7, and to the high-end X models as well. It’s also the next step in the the “2025 electric plans” which include at least 12 fully-electric BMWs and at minimum 13 PHEVs. We also believe that the next generation of the high-end limousine might forgo the gasoline and diesel engines, in favor of all-electric and plug-in hybrid drivetrains.
Of course, the drivetrain is only half the story with the refreshed 7 Series, which in my opinion, is one of the boldest mid-lifecycle updates that I’ve seen in BMW’s modern history. The design of the new 7 Series has been highly debated and even months later, it’s still a hot topic in the automotive industry.
But I will save the design “pep talk” for my 2019 750Li review, and instead, we will focus solely on the technology and driving experience of the 745Le.
The new 745Le, or simply 745e in the United States, will arrive in the Spring on this side of the pond and brings a significant drivetrain upgrade over the outgoing 740e. Instead of the 2.0 liter four-cylinder engine, the new 7 Series PHEV uses the brand’s popular 3.0 liter inline-six patron engine which aims to correct some of the power deficiencies of the 740e.
The petrol engine itself makes 286 horsepower and 332 pound-feet of torque, while the electric motor has a rated output of 113 horsepower and 195 pound-feet of torque, gains of 2 hp and 9 lb-ft. Total power output: around 394 horsepower and 442 lb-ft of torque.
The lithium-ion battery pack now has great energy density, storing 12 kilowatt hours of energy (10.4 kWh usable) compared with the prior model’s 9.2 kWh. Charging time for the 745e is 4.4 hours at a rate of 3.7 kW, ZF’s famed 8-speed automatic transmission is also integrated with the electric drive motor and has been slightly revised for the 745Le.
The high-voltage battery is positioned underneath the rear seats, while the 46-liter fuel tank (12 gallons) is located above the rear axle. This means that the luggage compartment volume of the plug-in hybrid models is only slightly restricted.
The electrically powered range of the new BMW 745e is between 54 and 58 kilometers (33-36 miles), while the new BMW 745Le reaches 52 to 55 kilometers (32-34 miles). The new BMW 745Le xDrive achieves an electrically powered range of 50 to 54 kilometers (31-33 miles). All these figures are for the European market, the EPA in the US has yet to publish the mpge figures. Regardless of the final figure, the electric driving range will be at least double of the 740e model.
The new BMW 745e accelerates in 5.2 seconds from zero to 100 km/h (62 mph), while the new BMW 745Le takes 5.3 seconds. Meanwhile the new BMW 745Le xDrive reaches the 100 km/h mark from standing in 5.1 seconds.
Though Europe will get several 7 Series PHEVs, the US market stays true to its strategy to only offer a long-wheelbase, all-wheel drive limousine. The 745Le xDrive sold in Europe is branded in the US as the 745e xDrive. Furthermore, US customers won’t see the M trim that puts an M logo on the front fenders.
The refinement of the 7 Series plug-in hybrid continues with three simplified driving models – Hybrid, Electric and Sport. The default mode is Hybrid (you can change that in the iDrive settings) which brings some speed restrictions for the all-electric drive – 109 km/h (68 mph), 20 km/h) faster than the predecessor models. If you switch to the always electric drive, the top speed bumps to 140 km/h (87 mph).
Starting off in Hybrid mode, I get the chance to experience the car’s updated drivetrain. Immediately I can sense the additional power and torque of the six-cylinder when compared to the 2.0 liter pot, and despite its heft – 4,848 lbs (2,200 kg) – the acceleration from standstill is quite punchy, With 41 percent of 7 Series being sold in China and 18 percent in the US, most of the world will see few 745e or 745Le models.
Europe is still heavy on 7 Series diesels, while the Middle East loves big engines, so I still expect that most of the 7 Series PHEV customers to come from United States. The PHEV revolution in the US has been happening for years now and BMW is selling a good chunk of them across their entire lineup.
