We've already seen some badass creations at this year's SEMA show in Las Vegas. Some of the highlights include a 600 hp supercharged F-150 from RTR, as well as a supercharged Chevy Silverado from GM. Toyota didn't want to be left out of the fun, so it decided to bring a 600 hp concept car as well. The only difference is that Toyota didn't bring a full-size pickup truck to the show. Instead, Toyota decided to base its SEMA concept on the C-HR crossover. The concept is called the C-HR R-Tuned, and it has completely caught us by surprise.

The regular C-HR isn't exactly what we'd call a good base for building a fast concept car. The stock crossover is powered by a sluggish 2.0-liter four-cylinder with just 144 hp. The engine is mated to a CVT transmission and takes a woeful 11 seconds to hit 60 mph while returning "ok" fuel economy. The concept was built by Dan Garder Spec (DG-Spec), who has worked some serious magic on this boring crossover. The stock engine and transmission were ditched entirely, and the car was given a multitude of upgrades. The new engine isn't all that new. DG-Spec used a Toyota 2AZ-FE engine, which can be found in Camry models from 2002 to 2011 as well as several other Toyota models.

The 2.4-liter engine is far from stock, with forged internals, a titanium and Inconel valvetrain, and a Garrett turbocharger producing 23 psi. The five-speed manual transmission is also modified, with a OS Giken limited-slip differential. The end result is 600 hp, which can rocket the C-HR R-Tuned up to 60 mph in just 2.9 seconds. This concept can stop on a dime thanks to front four-piston Brembo calipers with 14-inch rotors. It can also handle well thanks to adjustable shocks and 275-mm tires on all four corners. The interior has been gutted to fit racing seats and a roll cage. It's kind of a shame that Toyota will never really build something like this, much like Nissan never built the Juke-R.
