Here's a good read on the WTCC Chevorlet Cruze.


Louis Chevrolet, a race car designer and driver, co-founded Chevrolet with Billy Durant, establishing a racing heritage at the company's inception. That legacy continues today in many forms of motorsports, including the Chevrolet Cruze competing in the popular World Touring Car Championship (WTCC).
This year is the first full racing season for the Cruze, which was introduced in the WTCC in 2009, around the same time the all-new compact car was launched in the European market. This season also marks the sixth for Chevrolet participating in the WTCC; it includes three Cruze race cars and support teams.
The ambitions of the European Chevrolet WTCC team members this year are high, as they are aiming for the world title. It would be an achievement that would cap the steady progression since the Chevrolet WTCC racing debut in 2005.
The Cruze WTCC effort underwent significant development and testing to prepare for the 2010 season. It is directed by British stalwart racing organization Ray Mallock Limited (RML), which has been in charge of the technical and sports aspects of the racing program since 2005.
In 2005, when the Chevrolet brand was re-launched in Europe, it enrolled in the World Touring Car Championship (WTCC), one of only three FIA world Championships, next to Formula One and the World Rally Championship (WRC). The intent was – and remains – to demonstrate capability, durability and confidence in the products to the public, dealers and employees.
The WTCC features cars close to production models. "Real cars, real racing" is the championship’s tagline and it very appropriately encapsulates both the spirit of the WTCC and Chevrolet. With races taking place in different continents (Europe, the Americas, Asia and Africa) and offering a truly global audience, the WTCC is an ideal platform to showcase the Chevrolet spirit so well expressed by Louis Chevrolet’s motto: “Never give up!”

By looking at the HP and Torque numbers.. it seems this engine wasn't turbo? Just a 2.0L N/A? Huh.. that's a lot of power for such a small motor.

I guess I came to this conclusion since it should have made a lot more torque if it was turbo'd but maybe I'm wrong.. it doesn't say here

its n/a. i didnt find anything about them using a turbo motor in the racing series. there might be a restriction not allowing them to use one.

...the 1.6LT (RPO: LLU) engine used in Chinese Cruze compared to our 1.4LT (RPO: LUJ) engine:

1.6LT (LLU) = 8.8:1 CR; 181 hp/135kW @ 5800 rpm; 235 N·m @ 2200-5600 rpm

1.4LT (LUJ) = 9.5:1 CR; 138 hp/103kW @ 4900 rpm; 148 lb·ft @ 1850-4900 (auto)
1.4LT (LUJ) = 9.5:1 CR; 138 hp/103kW @ 4900 rpm; 148 lb·ft @ 2500-???? (manual)

Awesome specs but compare them to the 650+ HP of the Aussie touring cars which are only 200kg heavier - awesome+........."Formerly the Australian Touring Car Championship, the current formula was devised in 1993 (based on Group A regulations) and branded as 'V8 Supercars' in 1997. The series features grids of twenty-eight cars (although in endurance races e.g. the Bathurst 1000 there can be wildcard entries, which add to the grid) with 650+ hp (480 kW). The cars are Ford Falcons and Holden Commodores. The weight limit for a V8 Supercar is 1,350 kg (3,000 lb). At one time the cars were billed as the "biggest, heaviest, fastest and most powerful" of all touring cars. In terms of outright power, size and weight this is still likely to be true
