Performance and Fuel Economy (Subaru's Diesel Impreza STI)

Got word of it here: http://www.lease-hire.co.uk/latest-news/item/248

Seems pretty cool. Perhaps diesel is the future of "go fast"

Quote:
Power is set to come from the company’s all-new 2.0-litre flat-four cylinder boxer unit, which we tried for the first time in the Legacy Sport Tourer (Jan 2008). This will join the Impreza range in standard 148bhp guise this September. However, a tuned version with 180bhp could be used in a racy STI version.

Add a torque output of around 400Nm – up 50Nm on the petrol engine – and the high-performance model could sprint from 0-60mph in seven seconds and accelerate on to a top speed of 140mph. Yet the biggest benefit would be fuel economy of around 45mpg. As the boxer diesel is smaller than the STI’s petrol engine, it would be ideal for a performance model. The turbocharger is mounted beneath the engine, attached directly to the catalytic converters, to give a lower centre of gravity. The powerplant weighs no more than the current version, and would also help slash the STI’s emissions by nearly 40 per cent, from the petrol’s 243g/km to about 155g/km. That could reduce the Subaru’s road tax burden and attract fleet drivers when the car arrives next year.

At 180hp it won't be an STI. Probably a WRX equivalent. Sounds like a killer combo too bad the rest of the car is hideous.

Exactly! :drool:

Too bad the redesign is really WEAK. It doesn't exude "XTI" at all.

The current diesel has 148hp but a tuned version could easily put out 180-200hp.
200hp is a conservative figure for sure. For comparison the stock 1.9 TDI engine is 100 hp, while the 1.9 Race TDI engine puts out 190 hp with bigger holes, a bigger turbo and a bigger fuel pump.

I'm pretty sure there will be someone getting that beast close to 300 hp.
