Toyota Motorsport GmbH (TMG) will demonstrate its high-performance electric powertrain technology at the Pikes Peak International Hill Climb in Colorado on 8 July.
Last year TMG set a new electric vehicle lap record at the Nürburgring Nordschleife (7 min. 47.794 sec) with the road-legal TMG EV P001 car (earlier post), a record which still stands. TMG’s advanced electric and electronic department spent the subsequent months developing an updated electric powertrain, which is more powerful and more durable than its predecessor.
That high-performance electric powertrain is the heart of the new TMG EV P002 car, which will compete at Pikes Peak as part of a project from Japanese company RK1 Inc. Multiple Japanese rally champion Fumio Nutahara will drive the car which features prominent branding from Yokohama.

The hill-climb, which begins at an altitude of 2,800 m and reaches the summit of 4,300 m, is an ideal environment to showcase the strengths of an electric powertrain.
Based on a Radical chassis, the TMG EV P002 has a predicted top speed of 240 km/h (149 mph) in Pikes Peak configuration, with combined maximum power of 350 kW from its two EVO axial flux motors. TMG’s high-performance electric powertrain maintains full power despite the thin atmosphere at high altitude while delivering 900 N·m (664 lb-ft) of torque through its single-speed gearing (gear ratio 2.5).
As a comparison, the EV P001 at the Nürburgring delivered a top speed of 260 km/h (162 mph) with 280 kW from its twin motors and 800 N·m (590 lb-ft) of torque.
The TMG EV P002 underwent a successful three-day testing session at the Paul Ricard circuit in southern France in May to verify car and powertrain performance.
The EV P002 is powered by a 42 kWh lithium ceramic battery—i.e., incorporating Evonik’s Separion ceramic separator and Litarion electrodes (earlier post)—provided by the Evonik-Daimler joint venture Li-Tec Battery, with off-board DC charging.
