Toyota's blown 5.7 V8 'Hilux'

How fast can you make a Toyota bakkie using off-the-shelf parts?

To investigate this possibility, Toyota’s built a rather swift Tacoma RTR Concept, specifically assembled for quarter-mile racing.

The Tacoma is of course Toyota’s Americanised Hilux and runs the same 4l V6 found locally as its headline series production engine.

For its Tacoma RTR Concept, Toyota’s borrowed the driveline from its bigger US-market bakkie, the Tundra, and then set about trimming the package with performance parts by TRD.

Although Toyota already has a supercharged 4l V6 version of its Tacoma retailing as the X-Runner, this RTR is an even more ballistic bakkie.

Looks like a racer

Although the Tacoma’s surfacing remains stock a 115mm ride height reduction, combined with classic red and silver Toyota Tornado quarter-mile livery, give this bakkie an undeniable competition presence.

The combination of TRD and Tundra parts tally an interesting blend, especially considering it is a Tacoma chassis hosting the modifications. 

At the heart of this beastly bakkie is a 5.7l V8 lifted from the Tundra.

Boosted by a TRD blower - and gas-exchanging via a custom made 88mm diameter exhaust system – the Tacoma RTR is no quarter-mile trailer queen. Power peaks at a rather healthy 370kW, supported by 745Nm.

Should go like one too

Amazingly the standard Tundra six-speed automatic transmission is fully capable of channelling the blown 5.7l V8’s power to the rear wheels, where it partners with a trick TRD limited-slip differential assembled by Eaton.

Aligning the limited-slip differential and 30x11.5x15-inch Goodyear Eagle Dragway Special tyres is a standard Tundra axle reduced by 155mm to fit the Tacoma's rear tracking width. Toyota estimates this combination to be secure enough for an 11 sec quarter-mile time – which is quicker than Porsche’s 911 Turbo…

Reining in the Tacoma RTR is a set of brakes (engineered by StopTech) lifted from its X-Runner sibling, with rotors measuring 332mm in diameter - actuated by four-piston calipers.

Toyota’s Tacoma RTR will be the company’s star attraction at the SEMA auto show in Las Vegas, which opens during the second week of November.

The point of it all? To demonstrate just how quick you can go with some ingenuity and determination when raiding Toyota’s parts bin in search of ballistic bakkie performance.
