The Breakdown One is a 2000 X5 E53 with an M5 E60 V10 engine and a six-speed manual transmission. 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. 2000 BMW X5 Photo by: BMWThe Other Kith BMWIn addition to the X5 E53, Kith and BMW are also revealing a 2027 X5 in Frozen Titanium Silver. It’s inspired by the Titanium Silver Metallic on Fieg’s restored E53, and BMW will not offer it on the standard production X5. Motor1’s Take: The V10-powered BMW X5 E53 is the true star of this pairing.
