A range of electric delivery vehicles being developed for the North, Central and South American markets will use a highly integrated 70 kW powertrain from UK specialist Zytek. Developed with the support of a $39 million (£23 million) US Government grant, the vehicles will be manufactured by a new joint venture company being established by US truck supplier Navistar and British electric commercial vehicle specialist Modec.

The US Modec / Navistar application will be for a new generation of class 2c-3 vehicles optimized for suburban / urban pick and drop applications. To provide good performance for high productivity combined with excellent hill start capability when fully laden, the new vehicle will use a 70 kW, 300 N·m (221 lb-ft) version of Zytek’s E-Drive, which is also available in 55 kW, 120 N·m (89 lb-ft) and 55 kW 160 N·m (118 lb-ft) versions.

The grant will help fund the development, validation and deployment of an initial batch of 400 vehicles during 2010. Gross Vehicle Weight will be 12,100 lbs (5.5 tonnes) and the latest lithium-ion batteries will provide a range exceeding 100 miles.
Zytek’s E-Drive as a basis for EV development allows fast integration with new or existing vehicle platforms and is thoroughly proven. Current production applications for E-Drive range from the smart fourtwo electric city car, through a number of C-segment family sedans and light duty vans, to several categories of heavier commercial vehicle. Low volume vehicle build, typically for fleet trials, is conducted at Zytek, while for higher volumes the company supports assembly at the customer’s vehicle manufacturing facility, with the highly integrated design of E-Drive making it ideal for integration alongside standard models.
Zytek has also provided technology and integration expertise for General Motors and Chrysler to support production and concept vehicle programs.
In September, Zytek unveiled a fully engineered, electric version of the Mercedes A-Class that it developed in just ten weeks. Designed to demonstrate the capability of the company’s production-ready 55 kW E-Drive electric powertrain, the five-seat electric family car project is a Zytek in-house activity and is entirely independent of Mercedes-Benz.
