Ricardo’s newly launched GT transmission has been adopted by Toyota and Honda as the standard for the ultra-competitive 2010 Japanese Super GT race series, following its successful development with Nissan Motorsport (NISMO) in 2008. This advanced transmission product – acclaimed for its extremely light weight, durability and high reliability – is now to be made available for sale in a form providing an ideal solution for GT1 and GT2 applications.
This six-speed sequential transverse transaxle is designed for use in a front engined rear wheel drive GT application and is provided in an extremely lightweight magnesium non-structural casing. Alternatively, it can be provided in the form of the existing proven internals in a customer-bespoke casing and a longitudinal arrangement is also possible if desired. The racing provenance of this Ricardo product is truly impressive: it has successfully competed with excellent wear characteristics and 100 percent reliability in the 2009 Spa-Francorchamps 24hr race in the GT1 class, and its internals are identical to those of the 2008 and 2009 Japanese Super GT Championship winning cars. Most recently it was used by the British Sumo Power Nissan team in their victory in the Tourist Trophy at the UK’s Silverstone circuit on Sunday May 2, the first win for the new Nissan car in the 2010 FIA GT1 World Championship.
The Ricardo GT transmission has a capacity of 700 Nm torque and in excess of 650 bhp. It has a six-speed sequential dog engagement, with input bevel and spur gear final drive. Its gears are 16mm in width, straight cut and full form ground, and are manufactured from S156 single melt case hardened steel. With its magnesium casing the fully assembled transmission weighs only 53 kgs (117 lbs), giving it a significant performance advantage against its competitors.
Commenting on the launch of the new Ricardo GT transmission, Mark Barge, Ricardo’s director of high performance transmission systems said: “The adoption of the Ricardo GT transmission by the Japanese GT Association and its successful use by Nissan, Toyota and Honda is testament to its high quality of design and manufacture, extremely light weight, robust durability and extreme reliability. We are very pleased therefore to be able to make this transmission available to customers across a wide range of motorsport applications – whether as a complete product, an internal gear package, or in customized form specific to their particular requirements. This is a further example of the Ricardo approach of providing advanced and ultra-competitive motorsports products, in line with our philosophy of ‘winning through technology’.
