One is a 2000 X5 E53 with an M5 E60 V10 engine and a six-speed manual transmission.

The other is a 2027 X5 with an exclusive Frozen Titanium Silver exterior paint.

Both SUVs debut during this year’s Monterey Car Week.

BMW and Kith are back at it again with another collaboration—and this one might be their wildest idea yet. Later this week, the pair will unveil two special X5 SUVs separated by more than a quarter century during Monterey Car Week.

Ronnie Fieg, the founder of the New York-based streetware brand, has shoved BMW’s iconic 5.0-liter S85 V10 engine from the E60 M5 into a 2000 BMW X5 E53, the model’s first generation. The engine produced 500 horsepower in the sedan, which connects to a six-speed manual transmission in the SUV, while retaining its original all-wheel-drive system.
