An all-new powertrain is in the cards.
As evidenced by countless spy shots, the BMW 5 Series is about to be facelifted for the 2021 model year. The updated 5 Series (internally known as the G30 LCI) is expected to have various changes on the exterior as well as tech upgrades in the interior. There will also be a new plug-in hybrid variant that will be much different than the existing 530e model offered in the United States.
According to Bimmer Today, the updated 5 Series (including the new hybrid) will be revealed in the coming weeks, possibly even next week. The 530e plug-in hybrid model will be replaced by a new, more powerful model expected to be called the 545e.
Just like its larger 7 Series sibling, the 5 Series plug-in will transition from a turbocharged four-cylinder to a 3.0-liter turbocharged inline-six. The 545e should produce the same output as the larger 745e, meaning the inline-six will combine with an electric motor to produce 389 horsepower and 442 lb-ft of torque. 286 hp will be provided by the B58 inline-six while the electric motor contributes 113 hp to the total output.
These numbers would be a significant improvement over the 530e, which produces just 248 hp from its 2.0-liter four-cylinder and electric motor combination. With more power on tap, the 545e should hit 60 mph in under five seconds (compared to 5.9 seconds in the 530e). BMW currently offers the 530e with rear-wheel-drive or xDrive but it remains to be seen if both will be offered on the 545e.
BMW rates the 745e with 16 miles of electric range but we expect the 5 Series to travel a bit further due to its smaller stature and lighter weight. The current 5 Series plug-in is rated at 27 mpg combined (25 mpg with xDrive) though we suspect this more powerful six-cylinder car will be less efficient, just like the 7 Series. Pricing will likely be higher than the 530e, which starts at $53,900.
