ABOUT THE 2024 BMW X3 M40I
The 2024 BMW X3 M40i is the performance version of the third-generation X3 (G01), and 2024 was the last model year for this generation before the new G45 X3 arrived. It uses the turbocharged 3.0-litre inline-six (B58) with 48-volt mild-hybrid assistance, rated at 382 hp and 369 lb-ft, driving all four wheels through xDrive and an eight-speed automatic.
The final G01
The M40i received its mild-hybrid system as part of the X3’s 2022 facelift; the small starter-generator can add a brief boost of around 11 hp and smooths stop-start operation. In 2024 the M40i sat above the four-cylinder 30i models and below the full X3 M. X3 production for North America takes place at BMW’s plant in Spartanburg, South Carolina.
What it is like
The inline-six gives the M40i strong, linear performance and a distinctive sound, while M Sport suspension, M Sport brakes and a rear-biased tune of xDrive make it feel more agile than its size suggests. It keeps the regular X3’s five-seat cabin and practical boot, so it works as a family SUV as well as a fast one.
Buying one today
The B58 is widely regarded as one of BMW’s more durable modern engines. Points to check include coolant leaks from the expansion tank and pipes, oil filter housing gasket leaks on higher-mileage cars, and the condition of brakes and performance tyres, which wear faster on this version.
Rivals
Rivals in 2024 included the Porsche Macan S, the Audi SQ5, the Mercedes-AMG GLC 43 and the Genesis GV70 3.5T.
