Monterey's one-off E53 X5 with M5 V10 steals Car Week
A one-off 1st-gen BMW X5 E53 restomod by Kith packs the 5.0L S85 V10 from an E60 M5, paired with a six-speed manual and the X5’s AWD. With M Sport brakes and a bespoke black leather interior, the build—completed over a year by Ronnie Fieg’s brand—is considered Monterey Car Week’s standout, though no current power figures are released beyond the M5’s original 500 hp.
