Gordon Murray Design and Toray Industries have announced a prototype electric sports car named Teewave AR.1.
Multinational chemical company Toray commissioned Gordon Murray Design to design, tool and build a fully functioning prototype vehicle which used as many of Toray's advanced automotive materials as possible. The two-seat sports car, known inside GMD as the T.32, is based on a carbon fibre monocoque structure and was developed in just nine months.
A carbon front crash structure was designed and developed for the car and it has been subjected to a simulated EuroNCAP offset deformable barrier test in addition to a rigid barrier impact.
Despite carrying a 240kg battery the AR.1 has a total weight of just 850kg, around 400kg lighter than a Tesla Roadster.
The Teewave powertrain comes from the Mitsubishi i-Miev/Citroen C-Zero/Peugeot Ion, but with a unique electrical architecture and control units developed by GMD. The battery has a capacity of 16kWh and the mid-mounted electric motor which drives the rear wheels generates 47kW and 180Nm, which gives 0-100km/h (62mph) acceleration in 11.4sec. On the NEDC cycle the AR.1 has a range of 186km (116 miles) and a full recharge takes six hours.
The concept design team included Barry Lett, Frank Coppuck, Kevin Richards and Gordon Murray. Exterior and interior styling was designed by Zachary Seward, Kevin Richards, Barry Lett and Gordon Murray. The project leader at Gordon Murray Design was Mark Lewis. The main architecture design team was led by Barry Lett and the engineering, composites and analysis team were led by Frank Coppuck, while the electrical system and power train design was by Dr Ralph Clague.
The Toray team consisted of Toru Yamanaka, Project Leader, Nobuhiko Shimizu, Project Manager, Yukitane Kimoto, Composite Team Leader, Yoshito Kuroda, Yuki Sakamoto, Kosaku Hashimoto, Composite Team, Alan Riley, UK Composite Handling and Osamu Goto, Project Advisor from Geo Technology.
"It has been a pleasure to work with Toray Industries' team on this challenging project," said Gordon Murray. "The resultant vehicle weight of just 850Kg achieved using Toray's carbon fibre once again proves that performance through light weight is the most efficient and environmentally friendly way to achieve power to weight targets."
