LAS VEGAS, Nevada – Asked to name a Toyota that can outgun McLaren muscle and Porsche panache one probably wouldn’t suggest a Toyota, not even a C-HR. Hmmm…

Well, whatever, a 450kW,  race-tuned, version of the Toyota crossover has done it in against-the-clock testing in the USA.

While preparing for its debut at this year’s Sema speciality show in Las Vegas a C-HR R-Tuned lapped the four-kilometre Willow Springs International Raceway in California quicker than all but five production cars ever tested there, according to fastestlaps.com data.

DAN GARDNER CUSTOM JOB

“The hot Toyota’s notable scalps,” Toyota crowed, “include the McLaren 650 S Spyder, Porsche 911 GT3 and Nissan GT-R Nismo on its way to claiming the title of ‘world’s fastest crossover’.”

The project followed the Toyota Sienna R-Tuned MPV shown at Sema in 2015 and Toyota North America spokesman Steve Curtis said: “This car redefined the perception of what a family minivan can become with a bit of racing inspiration. The C-HR R-Tuned took it to another level.”

The custom job was done by Dan Gardner Spec (DG-Spec) with a more extreme treatment than that applied to the Sienna.

The C-HR R-Tuned has a 2.4-litre, four-cylinder, Toyota 2AZ-FE engine with Dezod forged internals, a titanium and Inconel valve train and a custom DG-Spec Garrett turbo system to take power output beyond 450kW.

The engine was hooked to a five-speed Toyota E-series manual transmission and thence to the front front wheels through an OS Giken limited-slip differential.

Toyota says the car was not designed to be just a straight-line dragster but for a combination of acceleration, braking and handling. Toyota enlarged: “It has Brembo racing brakes with 36cm front discs and four-piston aluminium Monobloc callipers and DG-Spec Motion Control Suspension racing shock-absorbers – along with many other custom go-faster components.”

The grip of 275/35R18 Toyo Proxes RR tyres was augmented by the downforce and stability control of an air dam, skirts, a front splitter and an imposing rear wing with a Gurney flap.

The result, Toyota said, was 136kg of downforce at high speeds and the cabin was stripped behind the front seats and that, as well as a vented carbon-fibre Kaminari bonnet, helped to shave hundreds of kilograms off the C-HR’s kerb weight.

The car was tested at Willow Springs on 10 occasions as the conversion progressed and performance data was logged.

‘NOT JUST  A SHOW CONCEPT’

DG-Spec owner Dan Gardner told Carman’s Corner in a media communications: “The C-HR R-Tuned has been to the track every month since we started the project in late 2016. It’s probably been subjected to more real-world tests than just about any car built for Sëma.

“It’s not just a show concept but a track-capable performance car and I can’t wait to see what people at Sema and beyond will think.”

  • The C-HR R-Tuned was among 18 Toyota vehicles on display at Sema, which closed on  Friday November 3.
