2023 BMW Z4 M40i Remains More Powerful In The US

In the past, European versions of cars offered in two power levels were more potent than their North American counterparts. With the third-generation BMW Z4, however, things are backwards; the M40i model offered in the United States is more powerful than its European counterpart. As a result of stronger emissions rules on the Old Continent, the G29’s initial release in August 2018 astonished many with its discovery of a substantial gap in output between continents.

The B58 engine included in the American variant produces a respectable 382 hp. In Europe, the identical turbocharged 3.0 litre engine is reduced by a noticeable 47 horsepower. Due to this, the inline-six can only muster 335 horsepower. If you’re a European reader, you won’t be happy to hear that the Z4 LCI’s statistics won’t change for the 2023 model year. Both versions of the M40i have the same torque output of 369 lb-ft.

The American version takes 4.4 seconds to reach 60 mph, but the European version takes a tenth of a second longer. The European Z4 M40i has the same 0-60 and 0-62 mph speeds as the US model.

BMW hasn’t made any mechanical upgrades to the LCI. The oily parts of the sDrive20i, sDrive30i, and M40i remain unaltered. However, the M Sport Package is standard on four-cylinder vehicles. The M40i ups the ante with standard adaptive M suspension, electronic shocks, and a rear differential, features that are only available as upgrades on the sDrive30i. After almost 55,000 pre-LCI BMW Z4s have been shipped, the updated model hits stores around the world in November.
