Car makers frequently make vague claims that their racing technology leads to improvements in road-going vehicles, but this is one of those precious few moments where the gains are very tangible. Jaguar is delivering an update to its I-Pace EV that promises up to 12 miles of extra range thanks partly to know-how gleaned from the eTrophy race series. The automaker has boosted the efficiency of the car’s AWD torque distribution, reduced use of the radiator vanes that keep it cool (improving aerodynamics) and allowed the battery to run to a lower state of charge without compromising performance or durability.
