Cosworth will provide the complete solution for the new GT race car
being developed by Chevron Racing Cars, the GR8.
Cosworth will provide its 2.0L YD race engine alongside high performance engine control and
instrumentation systems for the new mid-engined Chevron competition coupe. An initial run of 20 of the
new cars are being laid down for the one-make GR8 Challenge series, the opening event of which is
planned for early 2010.

Today Cosworth's ever expanding range of ready-to-race performance packages is based around
the YD (popularly referred to as the Duratec), which is generally considered to be the engine of choice for
mid level racing because of its lightweight construction and impressive power potential.
High performance race engines require a suitably advanced control system to provide optimum power
"under the curve" and ensure that the engine is able to deliver both performance and reliability.
The
Cosworth group includes a dedicated electronics division, which provides ECU solutions under the
Pectel Control Systems brand and industry leading data and instrumentation systems under the Pi
Research brand.
The Cosworth package that will be supplied for Chevron Racing Cars' new GR8 will include the Pectel CD4
unit, which offers high levels of precision and flexibility, using technologies derived from those that
have been used to win World Rally Championship and FIA GT titles.

The on-car electronics package is
completed by the Pi Omega LCD panel display, which provides crystal-clear readouts for the driver and
seamless integration with the engine control unit data.
Chevron Racing Cars has already released a concept study, which it says is fairly close to the final design.

Weighing around 600 kg, the Cosworth 2.0L YD will provide the new GR8 with a power to weight ratio in
excess of 400 bhp per tonne. Fabrication of the prototype is in progress and development testing is
scheduled to commence in January.
Jog Lall, General Manager & Director, Cosworth:
"It's gratifying to see that Cosworth's range of race technologies continues to deliver genuine value for
money performance in the current financial climate. I'm happy to be able to support enthusiastic, exciting
projects like Chevron with a complete solution that showcases the breadth of technology that is available
within our group. Electronics form a key part of modern racing cars and it's important to Cosworth that
we're are able to supply the complete solution for our customers – our electronics division makes this a
reality."

George Lendrum, Divisional Managing Director, Cosworth Electronics adds
"The GR8 design looks set to follow in the tracks of previous Chevrons like the superb B8. I'm very pleased
that Chevron came to Cosworth to provide the complete race technology solution for the car. Our high
performance electronics are able to deliver the very best from the YD and I'm looking forward to some
exciting races next season."
Helen Bashford-Malkie, former historic F1 racer and Director, Chevron Racing Cars:
"I'm delighted that the GR8 will employ a complete integrated package from Cosworth. Judging by the
interest we are receiving, next year looks like it will be a really exciting time for us. As well as UK
competitors in categories for current types of car and from others who race historics, we have had serious
enquiries from mainland Europe. A GR8 Series in 2010 in at least one country besides the UK is not out of
the question."
