Subaru releases brand new boxer engine details

Subaru’s new boxer engine details have just been released and the main result is better fuel economy than the existing models whilst maintaining plenty of power and torque.

The new Subaru normally-aspirated (non-turbo) engine is the third generation developed by Fuji Heavy Industries, Subaru’s father company, and it’s the first brand new engine since 1989.
Subaru engines have always been robust, fairly powerful and very torquey especially when matched to high-geared ratios within Subaru’s all-wheel drive system. But the engines weak link has always been consumption and economy. It’s not that the engines are bad on fuel, they just consume a little more than the rivals.
Now though, Subaru and Fuji Heavy Industries have improved this area with indications noting a 10 percent increase in fuel economy. This was done through the use of lighter moving parts and an Active Valve Control system for the intake and exhaust.
The new 2.0-litre engine uses undersquare bore and stroke measurements too, meaning the pistons travel further than they are wide; 84mm bore and a 90mm stroke. This helps with torque and reduces the engine’s inclination to want to rev higher for more performance. Figures of 109kW and 196Nm are on offer.
Managing Director, Subaru Australia, Nick Senior said in a recent report,

“This is an exciting engineering development from FHI. They’re renowned for the durability of their engines and this new unit will take the sophistication to a whole new level that we’ll look forward to experiencing in some versions of our best-selling Forester next year.”

Subaru says the new engine will be available in both 2.0-litre and 2.5-litre capacities and will first go into the market with the Subaru Forester model year 2011, which will be launched early next year.

Subaru Impreza WRX 2011

Subaru Impreza WRX 2011 is presented at the New York Auto Show.This new model has been improved and Subaru couldn`t just tweak the engine, they tweaked the body too. Subaru Impreza WRX 2011 has a wider track, with about 1.5″. The body modifications are completed with a new “face” and the 17″ wheels.
The new Subaru Impreza WRX 2011 has the same power specs as the previous model: 265Hp and 244lb-ft of torque.

These are very first spy shots of the Subaru and Toyota joint-developed rear-wheel-drive coupe. The test mule seen in the pictures looks like it’s sporting many body parts from the Legacy, albeit it’s apparent that coupe is much more compact in dimensions. We’re not so sure about the platform but in a previous official statement issued by the two Japanese carmakers, the yet unnamed coupes will be based on an all-new platform with power coming from Subaru’s range of boxer engines.

Judging by our experience that could translate to a modified version of the existing Impreza platform and 2.0 / 2.5-liter naturally aspirated and turbocharged engines. Needless to say that we can’t make any assumptions about the coupe’s appearance from the test mule pics. However, since both coupes are slated to enter production in 2011, expect a Toyota and Subaru concept version to appear sometime in 2009 with the production version making its official appearance in a major car show in 2010.

Subaru unwraps 2011 Subaru Impreza WRX with wider body design at New York Auto Show

Japanese carmaker Subaru unveils the 2011 Impreza WRX at the New York Auto Show. The design lines reveal the intention of the manufacturer to close the style gaps between the STI and the WRX models. The 2011 Impreza has a wider body and a more aggressive stance compared to the conservative look of the outgoing model.

The new Impreza WRX has a wider front and rear. It is also fitted with 17-inch alloy rims matched with 235/45R17 tires. Indeed the 2011 WRX is ready to pounce on the road compared to its older sibling.

The 4-door and the hatchback versions still sport the turbocharged 2.5L engine that can give out 265 horsepower. The engine is couped with a manual gearbox with a 5-speed configuration.
The wider body resulted to additional 33 pounds but it really doesn’t affect the performance of the car. The sedan will be 6.5 inches longer and logically offers more storage space than the hatchback version.

The design team also injected sharper bumper corners, wider fog lamps that are blacked out to blend well with the new profile. Some aerodynamic features were also added like the front spoiler on the lower lip.

I think description no needed. Just few words about creation this video..

Company Subaru has decided to create a series of the preview trailers propagandising new sedan WRX STI. The company has asked rally pilot Dave Mirra to take for a drive several people under one of platforms on the 305-strong car and has catch all this action on video.

As a result it has turned out five preview trailers. We too have looked them and now we ask a question and where to get this knob in the form of a skull on the aerial?

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.

2011 WRX STI sedan runs 'Ring in 7:55, quickest ever for Subaru

Quick: What's the fastest production sedan in the world? Does it wear a Mercedes-Benz, Audi or BMW badge? What about the Porsche Panamera Turbo or the Cadillac CTS-V? There's no doubt that each of these vehicular behemoths is capable of ripping off some fast times on a race track near you, but Subaru is out to prove that its new 2011 WRX STI sedan has the chops to keep pace with the best from the rest of the world.


To prove its point, Subaru recently sent test driver and four-time World Rally Champion Tommi Mäkinen out to the famed Nürburgring Nordschleife course in Germany with a 2011 STI test car. According to reports, the vehicle used in this testing was equipped with a few significant upgrades including a larger turbocharger that normally sees duty in the Japanese R205 model and some lightweight aluminum bits, but one thing is for certain: the 7:55 lap time is a mighty impressive result.

For those keeping track of such things, the previous best lap set by a Subaru WRX STI was in 2004 at 7:59.41 and the new mark set by Subaru – albeit with a
prototype, not a production car – is quicker than any of the aforementioned competition. Best of all, there's a video of one entire lap around the 'Ring and you can find the in-car footage after the break.

2011 Subaru WRX STI at Nurburgring [Video]

Subaru today announced that the Subaru Impreza WRX STI Sedan has become the fastest WRX STI Ever. It recorded a Nurburgring time of 7’55’’00, the fastest lap time ever in a Subaru.The production car goes on sale this summer.

Some of the upgrades received by the 2011 Subaru Impreza WRX STI sedan include an improved chassis and suspension, and as Makinen commented, the car is controllable and precise even on tricky corners.

The test 2011 Subaru STI Sedan has the same turbo brake calipers, flexible tower bar and front lip spoiler as the R205 model from Japan. The car also has the same Bridgestone Potenza RE070 tires and aluminum hood as the 2011 Subaru STI spec C car.

The 2011 Subaru WRX STI is powered by a 305-hp turbocharged/intercooled 4-cylinder Boxer engine and 6-speed manual transmission. It comes with a lowered ride height and new pillow-ball, higher-rate springs for both front and rear suspensions, and spring rates increased by 15.6 percent in front and 53 percent in the rear.

Subaru Releases Test Footage of Advanced Subaru WRX STI Research and Development from Nurburgring, Germany

CHERRY HILL, N.J., June 8 - Subaru today released footage covering advanced research and development carried out at the Nurburgring's racetrack in Germany, using a 2011MY Subaru WRX STI 4-door (sedan) test vehicle. Subaru has been using the famous Nordschleife course since 1992 for advanced R&D as well as tests of the WRX and WRX STI models. The video uploaded on the Subaru Global Site www.subaru-global.com features this year's development work. It is presented as a highlight of Subaru's persistent effort to stretch vehicle performance to unprecedented levels.

The concept of the 2011MY WRX STI is "The Fastest WRX STI Ever." At Subaru, the phrase "Fastest" refers to more than just top speed or maximum engine output. It implies driving with confidence. The WRX STI can be taken to its "fastest ever" performance by providing the driver with total driving control with confidence. Major upgrades to the 2011MY WRX STI focused on the chassis and suspension set-up, and tests at the Nurburgring demonstrated the supreme overall dynamics and linear behavior of the new STI. Tommi Makinen, the legendary four-time World Rally Champion, piloted the test vehicle for the development. He commented, "The car was controllable with precise and faithful handling even on tricky corners. I could easily predict the car's behavior. That is exactly what Subaru is offering, confidence. As a result, the 2011MY WRX STI test vehicle recorded 7'55''00, Subaru's fastest lap time ever, which is 4 seconds faster than the previous fastest time recorded in 2004."

The 2011MY WRX STI 4-door will go on sale world-wide this summer. Upgrades to the 4-door version will be carried over to the 5-door model.

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.

Subaru Launches Impreza WRX STI Spec C for Japanese Market

We wouldn’t exactly call Subaru’s WRX STI “soft,” but the Japanese automaker has just launched the WRX STI Spec C--a performance-tuned variant exclusively for the Japanese market.

Sure, the Spec C still uses the same 2.0-liter turbocharged boxer-four underhood, but engineers made a few small tweaks to boost performance. A redesigned turbocharger, along with a re-mapped engine computer, are said to help reduce turbo lag and improve the car’s top-end. The STI Spec C also receives an intercooler water injector, allowing intake air to remain cool, even at speed.

In the twisties, drivers will likely notice tighter steering and less body roll, thanks in part to a reinforced front suspension crossmember, stiffer coil springs, and unique rear sub-frame bushings. Subaru also replaced the rear differential with a Torsion-type unit, designed to enhance traction in corners.


If that weren’t enough, engineers put the STI on a crash diet. The Spec C gains an aluminum hood, laminate side windows, a smaller battery, and loses a spare tire in the name of saving weight. Subaru also developed a new set of 18-inch aluminum wheels (shod in Bridgetson Potenza RE070 rubber) said to further reduce unsprung weight.
If this sounds like your dream Impreza, rest assured it will remain that way. Only 900 examples will be built, and unless you’re living in Japan, it won’t be sold in your neck of the woods.
