If there's one number you'd associate with the Subaru Impreza, surely it'd be Four. Four generations, four doors, four-wheel drive, four cylinders in a boxer configuration. But in this Japanese market promo clip, Subaru has brought in another kind of boxer: the beat boxer.
I will freely admit to struggling with why Subaru continues to stubbornly employ a boxer engine design while so few other automakers do the same. After all, with twice the number of cylinder heads and cams as a traditional inline four-cylinder engine, a boxer four is more complex, more expensive to manufacture and more cumbersome to service with few tangible benefits. Until recently, the company's engines struggled to meet the fuel economy numbers of its competitors while offering no real boon i
According to Automotive News, Subaru is set to release a new, more fuel-efficient version of its boxer four-cylinder engine. The powerplant should be available in both 2.0-liter and 2.5-liter configurations and will be able to offer up a 10-percent boost in fuel economy over its predecessors. The report doesn't detail exactly how the engine goes about gaining its new found efficiency, but it does say the changes are the first significant revision of the company's boxer architecture in two decade
Inside Line is reporting that the new, RWD coupe being developed by Subaru and Toyota will only be sold as a Subaru in markets outside of Japan, while the Toyota version will remain exclusive to the Land of the Rising Sun. The report goes on to say that the coupe will be based off the Subaru Impreza (despite Toyota/Subaru's own press release saying that it's an "all-new" platform) and that power will be provided by a naturally aspirated, 2.0-liter boxer engine producing 220 hp at 6,500 rpm.
So we were all ready to start going over the technical details of Subaru's new turbo diesel boxer, but after digging through the PR materials, we realized they gave us bupkis. No power figures, no displacement information, not even what models they intend to shove the new mill into. L-A-M-E. Regardless, what we do know is that the horizontally opposed engine won't need a balancer shaft and, of course, it will be attached to Subaru's symmetrical AWD system. Sales will be exclusive to Europe when
Last fall Subaru announced plans to introduce a diesel engine with their classic boxer configuration. At next month's Geneva Motor Show, Subaru will be displaying the new oil-burning horizontally opposed four cylinder engine. Subaru plans to install the new engine in the Legacy and Outback starting early in 2008. According to Car magazine the engine is expected to produce about 165hp and 250 lb-ft of torque. The Subaru press release is after the jump.
New Subaru Impreza renderings seem to be coming out of the woodwork as of late, and judging by the similarities between the magazine scan we brought you earlier in the week and these newest images courtesy of AutoExpress, either the artist is the same or the new nose and hatch design has been rendered with the same information. Come New York, we shall see.
When you mate Subaru's blown boxer and all-wheel-drive system to a lightweight body, only good things can come of it. The P2 from Prodrive has already proven that much. But, when another British racing firm creates their own bespoke machine, the hairs on the back of our neck stand at attention.
The design of the horizontally-opposed engine has a myriad of benefits. One of the most common is its compact design, which allows the center of gravity to be lower in the host vehicle. Additionally, since the boxer's pistons cancel out much of the vibration, the rotational balance is second to none. Both of these advantages will lend themselves to the advent of the first boxer diesel, which will find a home within a variety of Subaru models in Europe and possible even here in the States.
