Porsche Cayenne diesel to be offered in US for first time; signals increased US diesel uptake
3 April 2012

The Porsche Cayenne Diesel will be sold in America for the first time, it has been confirmed at the New York motor show today.

The decision to put the diesel 3.0-litre V6 on sale highlights a small but growing shift in the US towards diesel, underpinned by rising fuel prices.

The Cayenne Diesel has 240bhp and 406lb ft of torque from 1750 rpm. It travels from 0-60mph in 7.2 seconds and a top speed of 135mph.

The new Porsche Boxster and Porsche 911 Carrera Cabriolet are also on display at the New York motor show.

When you look at the changes to the fuel quality of diesel taking place in the US to bring it into line with Europe's and the emissions regulations drawn up between the engine makers and Federal authorities then the growth in diesel sales in the US could be big. The savings in total US road fuel consumption would be huge if half of car and pickup truck drivers switched to diesel.

The demand for diesel SUVs in the states is increasing rapidly (as is the demand for most diesel cars there) - the ML-Class, X5, Q7 and Touareg have already offered the choice of a diesel engine in the US, and I'm not at all surprised to see Porsche following. If anything, I'm surprised it took 'em so bloody long!

I can't say I noticed that in Boston when I was there in February. Virtually everything, and I mean everything, seemed to be powered by a V8 petrol engine, including commercial vehicles.

I watched a builder pull away from a site in a new Chevy Silverado Work Truck (base model). It had the 6.0 litre Vortec V8 and Allison heavy-duty six-speed automatic, which was typical.

The 6.6 diesel is only used for super-duty towing jobs.

what's that, about 180hp?

This model year the base truck is not available with the 6.0 litre V8 but a V6 or smaller V8.

The two heavier duty models, 2500 and 3500, are available with petrol 6.0 litre V8 or the 6.6 litre V8 diesel. They also sell a petrol hybrid model this year.

The Chevy website shows the Allison 6 speed auto is fitted to the diesel version and a standard GM auto box to the petrol V8, to handle the higher torque of the diesel perhaps?

Sorry.

Perhaps it was a higher spec. It definitely had the 6.0, though.

No, about 320.

I know what you mean about gutless American V8s, though. I drove a Lincoln Town Car in Boston and while it was super-smooth and sounded suitably burbly, fast it wasn't. I think it was putting out about 240 bhp on paper, but it didn't feel like much more than 160.

How many builders in the UK would run a 6.0 litre petrol V8 or indeed a 6.6 V8 diesel with our fuel prices though? I think its nearly $4 per US gallon now in the states compared with our £1.45 per litre.

You also have to imagine why US builders drive Silverados and ours drive Transits. Are US houses bigger/heavier than ours?

It might have something to do with towing. One is allowed to pull a much larger and heavier trailer than here. The 6.6 Silverado is capable of pulling a ridiculous weight.

[quote mrcliodCi]I can't say I noticed that in Boston when I was there in February.[/quote]I agree 'mrcliodCi'. No noticable shift to diesel here in Florida either. Diesel is about 8% more expensive than premium here so a diesel Cayenne makes little if any sense whatsoever. As for Americans shifting en-mass to diesel, that's a pipe dream and just as well. I did read there is not enough 'diesel' refined for such a move, it being something of a by-product of the refining of gasoline. I don't think Porsche's decision is based on customer demand, more on fleet consumption averages and PR objectives.
