new Boxer motor from subaru

[Lapsed]

Subaru are releasing a new 3.6L H6 with the 2008 Tribeca. here is a bit of info on the motor.

MORE POWER: NEW 3.6-LITER H6 ENGINE

The dramatic exterior styling changes reflect the major changes under the skin for the 2008 Subaru Tribeca. A new 3.6-liter boxer engine has been designed with a goal of improving low-end torque and also lowering consumer running costs with a change to regular unleaded fuel. The larger engine displacement has increased engine torque to 247 lb.-ft., up from 215, and horsepower to 256 from 245, providing improved low-end torque without sacrificing high-rpm power. The new engine package, despite the larger engine size, not only maintains emissions levels but delivers improved fuel efficiency in real world driving situations.

To achieve these goals without affecting engine packaging, a unique shortened con rod was created to allow for a new and larger displacement engine without increasing the physical dimensions of the power unit. Keeping the deck height of the engine the same, the Tribeca is able to maintain its excellent low center of gravity. Improved cooling efficiency - needed to achieve the use of regular fuel - was achieved through a new common rail cooling system that individually cools each cylinder with water separation chambers rather than allowing water to flow from cylinder to cylinder. This allows for increased engine efficiency and standardized timing for all cylinders.

The new 3.6-liter engine features Active Valve Control System (AVCS) variable valve timing on both the intake and exhaust valves (the 3.0-liter engine had AVCS on the intake side only).

The new 3.6-liter H6 engine is connected to a substantially revised 5-speed automatic transmission that features an all-new torque lock-up converter and a new transmission control unit that deliver faster shifts and quicker reaction time. The new transmission delivers smoother shifts with less lag time and weighs less than the previous system, for a total weight reduction of 9.7-lbs. for the new drivetrain.

The transmission drives through the Subaru Symmetrical All-Wheel Drive system. Enhancing the AWD system are standard Variable Torque Distribution (VTD), standard Vehicle Dynamics Control (VDC) and four-wheel traction control system (TCS).

I wonder how long it will take for someone to try and put it in an L or MY... hehe

My thoughts exactly. That and/or a turbo.

[Subyroo]

Wish I had to money and the guts to try one out in my Forester

[PeeJay]

I've been thinking about doing up an Outback recently....

Mabey next year.

Now that would be a great start to a lifted Tribecca

Subaru’s versatile Model Year 2008 Tribeca is launched today with subtle styling changes, more power, better fuel efficiency and easier third row seat access in seven-seat models.

While specification is significantly enhanced, pricing is unchanged, starting from $53,990 for the Tribeca 3.6R five-seat.

Revised rear suspension on Subaru’s Medium Sports Utility Vehicle (SUV) benefits ride quality, while significant transmission refinements enhance drivability too, producing an agile constant All-Wheel Drive performer.

Tribeca’s new 3.6 litre six-cylinder horizontally opposed boxer engine is the largest ever produced by Subaru, yet it retains the same dimensions as the superseded 3.0 litre unit and is 0.7 kg lighter.

Power is up 5.5 per cent from 180 Kilowatts to 190 kW, while torque is up an impressive 17.8 per cent from 297 Newtonmetres to 350 Nm.

The end result is vastly improved low-end torque and better fuel economy – 11.6 litres per 100 kilometres versus 12.4 in the superseded model.

Despite the larger engine, emissions are unchanged.

Tribeca’s revised lighter-weight SPORTSHIFT five-speed automatic transmission produces smoother shifts and less lag.

Towing capacity is also enhanced, with the 2000 kg braked capacity download now increased from 100 kg to 160 kg.

Among the Model Year 2008 Tribeca highlights:
· Significant increases in torque and power – the all-new 3.6 litre engine is Subaru’s largest ever, yet is lighter
· Pricing unchanged – starts from $53,990
· Dynamic driving performance
· Optimum fuel consumption via improved low and mid-range torque – 11.6 l/100 km
· Lightweight five-speed SPORTSHIFT transmission – smoother gear changes, weight down 3.7 kg
· Simplified third row seat access in seven-seat models
· Recalibrated rear suspension for optimum ride comfort and handling
· Larger rear quarter windows for better visibility – size up 30 per cent
· New 10-spoke design 18-inch alloy wheels
· New exterior highlights including revised headlights, bumpers and grille
· ANCAP five-star rating for occupant safety
· Choice of five and seven-seat versions in both entry-level and Premium trims
· Exhaust, cooling and power steering revised
· Improved towing – 2000 kg braked capacity now enhanced by 160 kg download
· Xenon HID headlights
· Roof rails on Premium variants

Nick Senior, Managing Director, Subaru Australia, said: “Tribeca’s already impressive specification is vastly improved for 2008, while pricing remains the same, which is remarkable value for money.

“We will continue to offer both five and seven-seat options in 3.6R and 3.6R Premium trim levels.

“Yet again the Subaru engineers have achieved a remarkable feat in producing a greater capacity engine that is lighter, yet equally compact as its predecessor, and more fuel efficient.

“The revised SPORTSHIFT transmission is also mapped to ideally match the new engine’s characteristics, producing an ultra-smooth, responsive drive right across the operating range.

“We’ve been delighted by the customer response to the original Tribeca and judging by the huge level of interest in the new version displayed at Sydney Motor Show, we can only see its appeal growing.

“Tribeca maintains the five-star ANCAP rating for occupant safety now shared by the entire Subaru range and combined with its exciting new look, constant All-Wheel Drive ability, tremendous specification and competitive pricing, it makes a compelling package.”
