Revealed: Subaru Cosworth Impreza WRX STI CS400 Road-Going Rally Car

Subaru and Cosworth teased us earlier this year with a monster WRX STI, but now the full details on the finished product -- the Cosworth WRX STI CS400 -- have been revealed.

As Cosworth’s forte lies with engines, it’s not too surprising to read that the majority of CS400’s changes rest within the engine compartment. The CS400 retains the STI’s turbocharged 2.5-liter boxer-four-cylinder engine, but it’s received some serious surgery. Cosworth installs new high-performance pistons, high-strength steel connecting rods, and Cosworth-designed engine bearings. A new Cosworth-designed head gasket is also added, along with a high-pressure oil pump, and a revised turbocharger compressor and wastegate.


Cosworth hasn’t disclosed the boost pressures used, but the revisions -- along with a new exhaust system and revised ECU -- are enough to get the turbocharged engine pumping out 395 horsepower and 398 pound-feet of torque. That’s roughly 90 ponies and 103 pound-feet more than a U.S.-spec 2011 WRX STI.

We’d celebrate the car simply for the extra power, but Cosworth didn’t stop there. Engineers at the tuning firm partnered with Bilstein and Eibach to revamp the WRX’s chassis tuning to incorporate new coil springs that drop the ride height by a half-inch. Fourteen-inch AP Racing brake discs were added all around, a significant improvement over the 13- and 12.6-inch front and rear discs used on the 2011 STI.

Cosmetic tweaks are subtle, but they do help differentiate the CS400 from a standard WRX STI. Cossie-tuned Imprezas receive a new front fascia with foglamps, a mesh grille insert, and a unique rear spoiler. Larger 18-inch wheels not only help dress up the car’s appearance, but also increase the STI’s track by a half-inch. Buyers have little say in the exterior décor, but can choose between three paint colors (red, silver, and dark grey). Inside, all cars receive Recaro racing seats in lieu of the stock front buckets.

Only 75 of these incredible machines will be produced, and as we suspected, none will (legally) make their way to North America. The entire production run will consist of right-hand-drive models and will be sold in the United Kingdom. The CS400 will cost a whopping £22,505 more than the base WRX STI, bringing the total to £49,995.

Lamborghini Super Trofeo Racing Series Returns for Season Two

Europe is home to some of the finest racing series in the world and the Lamborghini Super Trofeo spec series is gearing up for its second season.

Never heard of the Super Trofeo? These racecars are lightened versions of the Gallardo LP 560-4 dressed in Blancpain livery and prepped for race duty. The Gallardo’s 5.2-liter V-10 puts out 570 horsepower while a retuned six-speed e.gear sends power to the all-wheel-drive system. High-friction steel brakes, “racing” ABS, a special aero package, and 18-inch competition wheels wrapped in Pirelli slicks complement the Super Trofeo’s 2900-pound weight. The chassis has been reworked and launch control has also been eliminated.


This year, the six-round season starts the weekend of April 24-25 at the Hockenheimring in Germany. The first round will support the DTM touring-car series; the remaining events will be paired with venues from FIA GT1 World, Le Mans Series, and Campionato Italiano di Gran Turismo. Each round contains 30 minutes of free practice, a 30-minute qualifying session, and three 40-minute races.

“The second Lamborghini Blancpain Super Trofeo season is highly anticipated,” said Manfred Fitzgerald, Lamborghini’s director of brand and design. “We’re excited to see new teams join the Super Trofeo family for 2010, while competitors from last season will return to defend their honours. The on-track battles were extremely close in 2009, and we’re set for another thrilling season ahead.”

2010 Lamborghini Blancpain Super Trofeo Calendar

Helio Castroneves Takes his Fourth Indy 500 Pole

The 2010 Indianapolis 500 won’t start until May 30, but as is so often the case with motorsports events, the action isn’t relegated to one weekend -- or, for that matter, one day. Pole Day -- the official qualifying day for the 500 -- was this past Saturday, and determined the starting order for the 500.

After besting his 2009 qualifying speed by over 3 mph, Helio Castroneves will sit in the pole position once again -- and be the first back-top-back Indy 500 pole-sitter since Scott Brayton’s performances in 1995 and 1996. Castroneves earned the position -- his fourth pole qualification at Indy -- by lapping the 2.5-mile track at 227.970 mph (in 2009, his grid-topping speed was 224.864 mph).

Before snagging the lead starting position, Castroneves held second behind Alex Tagliani. With just an hour and a half left in qualifying, Team Penske withdrew Castroneves’ time for a chance to snag the top position. It paid off -- although he had to sit through a tense 90 minutes as he watched other drivers approach his speed.

“Sitting in that car for an hour and a half was not easy at all, especially with everyone getting closer and closer,” said Castroneves. “I was like, ‘Are we going or not?’ because I can’t handle that much pressure.”

At the end of the day, only Castroneves and teammate Will Power (227.578 mph) posted speeds above 227 mph. Ryan Briscoe, Team Penske’s third driver, will start in fourth place, just behind Dario Franchitti. Tagliani -- who once looked to be the front-runner for pole position -- will start the race from fifth place. Scott Dixon, Graham Rahal, Ed Carpenter, and Hideki Mutoh round out the first three rows respectively.

There are some notable absentees from the top nine positions. Ryan Hunter Reay, who currently sits fourth in points in the 2010 IndyCar series, will start the race from the 17th position, while 2008 Indy 500 winner Dan Wheldon will start in 18th place. Danica Patrick will start the race in 23rd place, attributing her dismal qualification to “one of the worst” cars she’s ever driven. Regardless, she did better than 2004 IndyCar champion Tony Kanaan, who crashed twice in 24 hours exiting Turn One. It’s rather miraculous that the Andretti Motorsports team was able to restore his car for yesterday’s Bump Day, which allowed him to earn a 32nd-place starting position, just shy of last place.

Will Castroneves become the fourth driver to win the Indy 500 four times, and earn back-to-back wins from a pole starting position? We’ll know this Sunday after the checkered flag drops at Indy. Look for the race to start at 1:15 p.m. (EST) on Sunday.

Brabus Gives Mercedes-Benz SL65 AMG Black Series More Power, More Black Paint

In its search for more power, Brabus created the T65 RS using the Mercedes-Benz SL65 AMG Black Series and endowed it with 788 horsepower and 811 pound-feet of torque.

Starting with an already exclusive SL65 AMG Black Series, Brabus modified the factory twin-turbo 6.0-liter V-12 with some additional components. Two new exhaust manifolds with two new turbochargers were fitted to the twelve-cylinder engine, as were four large intercoolers to really get the air flowing. Feeding out from the engine is a stainless-steel exhaust system with free-flow cats.

To help harness the extra power, the SL65 Black Series was given a new engine electronics package that helps the car meet Euro IV emissions standards. In actuality, maximum torque is rated to an astounding 1047 pound-feet at 2100 rpm, but Brabus chose to electronically limit the car to 811 pound-feet, likely for drivability concerns. Peak horsepower is reached at 5500 rpm.

Unfortunately, extra power doesn't always translate to lower 0-to-60-mph times. We tested the standard Black Series to reach the mark in 3.6 seconds and the T65 RS posts the same number. In other performance figures, the T65 RS hits 124 mph in just 9.8 seconds and is capable of traveling in excess of 206 mph, but is also electronically governed to 200 mph.

As you can tell from the photos, the T65 RS really rides the Black Series name with its matte-black paintjob and darkened wheels. A special carbon-fiber hood scoop, black leather and Alcantara seats, and stainless-steel door sill plates with illuminated Brabus logos add the special German tuner touch.

Pricing has not been revealed, but with a starting price tag of $300,000 for the basic SL65 AMG Black Series, you can bet the T65 RS will command a premium.

Build Your Own: Dealers Design Last Batch of Special-Edition 2010 Dodge Viper

Dodge has had no trouble crafting its own special-edition models to celebrate the end of the 2010 Viper's production run, but it's now opening the fun to select dealerships as well.

Dealers who managed to sell high volumes of Dodge's two-seat sports car have been awarded the chance to design their own special-edition cars. For the most part, the custom Vipers are relegated to special paint schemes for the SRT10 roadster, the SRT10 coupe, and the SRT10 ACR coupe.


Thus far, Chrysler's revealed three examples of the dealer-custom program. The snake crafted by Woodhouse Dodge in Blair, Nebraska, is perhaps most unique -- the yellow Viper breaks from tradition and applies many of the unique touches found on the Viper ACR coupe to a drop-top roadster. Tromball Dodge created the "Reverse SRT10 ACR," which inverts the color combination used earlier this year on the Snakeskin Green Special Edition. Roanoke Dodge in Roanoke, Illinois, chose to apply dual Plum Crazy racing stripes on a black SRT10 coupe.

As is the case with the umpteen other special-edition Vipers we've seen this year, production of the Dealer Exclusive Program cars will be limited to 50 in total -- roughly ten percent of the entire 2010 Viper production run.

Is Subaru Considering a Diesel-Powered WRX STI for Europe

Subaru Tecnica Institute has produced high performance vehicles for over 22 years, but for the first time in its history, there may soon be a diesel-powered Subaru Impreza, tuned for performance, in Europe.


Subaru developed a diesel variant of its famous boxer engine for Europe, which made its debut at the Frankfurt Motor Show back in 2007. Fast forward to January 2009, when it launched the diesel-powered Impreza for Europe, whose 2.0-liter flat four turbocharged engine produced 227 horsepower and 236 pound-feet of torque, mated to a six-speed manual transmission. With Europe's strict emission laws, a diesel-powered STI could be just what Subaru needs to remain compliant.

But will a diesel-powered STI be able to compete with its gasoline-powered stable mate? With a little massaging from Subaru's in-house racing division, it should easily be able to compete. With its low center of gravity, superior fuel economy and low-end torque, a diesel boxer would make perfect sense for the STI. A 2.5-liter turbocharged flat-four gasoline powered STI pumps out 305 horsepower and 290 pound-feet of torque, and we're confident Subaru wouldn't release an oil burning Impreza WRX STI unless it was comparable to the gasoline version.

Just this week, we reported that Subaru greatly improved upon the 2011 STI's handling characteristics. New anti-roll bars, stiffer springs, improved bushings and a lowered ride height all combine for the improved handling. With its improved equipment, the Subaru just lapped the Nürburgring Nordschleife in a record-breaking 7:55. If the rumors from Autocar are true, don't expect a diesel STI to be launched until the Impreza enters its next generation for the 2012 model year.

Stunning Stingray: Convertible Chevy Corvette Stingray Concept Spotted?

Allow us, if you will, to play paparazzo for a moment and show you what may be an up-and-coming movie star. Photos of what appear to be a convertible version of the Chevrolet Corvette Stingray (or Centennial) concept recently appeared online, and we wouldn't be surprised if the car is destined for a career in Hollywood.


You may have seen the coupe version of the Stingray in person at the 2009 Chicago Auto Show, but there’s a better chance you saw it on the silver screen. GM’s Corvette Centennial concept was tapped by director Michael Bay for Transformers 2: Revenge of the Fallen, his 2009 sequel to Transformers.

So, then, what is this? We’ve no idea, other than the fact that someone (GM designers? Bay himself? Robotic alien creatures?) in the Southern California area managed to transform the striking coupe design into an angular roadster. Apart from the stubby wrap-around windshield and the waterfall decklid, we note a few other striking differences between this and the original Stingray concept design:

-a new hood, with two intake nostrils flanking a hood bulge that gives us flashbacks of the C3 ZL1 prototype

-new wheels, which adopt a new five-spoke pattern with deeply offset rims

-deeper front intakes, which appear to house fog/running lamps of some kind in their upper corners. These lamps seem to have replaced the slender, LED lamps that ran up the leading edge of the coupe’s front fenders

The Internet is abuzz with speculation of this car’s origins -- but seeing as Bay is already at work at a Transformers 3 and the car was spotted near a major film industry hotspot, we wouldn’t be surprised to see this ‘Vette gain a supporting role in the upcoming film.
