Lotus's Theory 1 concept promises electric sports cars worthy of the legendary British brand at last. Here's how it ticks the right boxes.

You step into the car through the head-turning doors that slide back and upward, taking part of the roof with it for easy driver access. Then you perch your bum on the smooth carbon fibre in front of the passenger seat, and simply slide across into the central driver’s seat.

Theory 1 features Lotus’ new “Lotuswear” interior that promises an immersive and personalized driving experience. It adapts physically to the driver and passengers, making seats more comfortable and communicating with lights and haptic feedback that can tell you when to make a turn, for example.
