How it works

Drive there. Track. Swap. Back out. Drive home.

  1. 01

    Drive there

    Drive there: designed for road use, subject to approval of the delivered car.

  2. 02

    Track

    A focused session of about ten minutes.

  3. 03

    Swap

    Removable energy modules exchanged in the pit lane.

  4. 04

    Back out

    The car returns to the track while the used modules charge off-car.

  5. 05

    Drive home

    Leave with energy, not a queue for a charger.

Batteries are intended to exchange in around three minutes and recharge off-car, so vehicle availability is separated from battery charging time.

Approximately three minutes is the battery exchange target TARGET. It is not a guarantee covering inspection, handover or thermal recovery. The planning rhythm is a 15-minute dispatch slot per run, with ten morning and ten afternoon runs per car. Road use depends on approval of the delivered configuration; route energy, circuit access and a charged set for the return journey must be arranged. No road range or remote swap network is promised.

Lightweight first

Built on real MK road + track DNA

MK has built lightweight road and track cars for decades. The electric programme keeps that philosophy: low mass first, responsive torque, and modest energy per session. VDK brings the 48V electric integration, swappable energy system and thermal validation.
