It appears the ML's diesel outdoes the just-announced Porsche diesel coming to the US in the Cayenne.

"Porsche has announced plans to offer two new models in the United States.

...the company confirmed the Cayenne Diesel will become the brand's "first compression-ignition car in the USA." It has a 3.0-liter V6 engine that produces 245 PS (180 kW / 242 hp) and 550 Nm (406 lb-ft) of torque. This enables the crossover to accelerate from 0-100 km/h (0-62 mph) in 7.6 seconds and hit a top speed of 220 km/h (137 mph)." --WorldCarFans.com

So the horsepower between the two is a virtual tie, but the ML has 49 more lb ft of torque. and is rated at 0.3 s faster to 60, and 2.5 mph higher top speed.

Porsche tends to be conservative their engines and the 0-60 times.

Like the 911 Turbo. Porsche rated at 3.5 0 -60 tested at 2.8
The Porsche 911 Turbo S. Rated at 3.1 0 -60 tested at 2.7 0 - 60

They are also stating it should be rated in the low 30s US mpg range.

Maybe they found the balance of economy and speed. I am sure most car companies would say consumers looking for MPG are not that concerned about speed. Mostly .3 hundreds of a seconds worth.

Are they (Porsche) using the same diesel engine found in the Touareg? For that matter, the same engine found in the Q7? Maybe a tweaked/modified version?

In the real world, 50-100 is far more useful far more often. I'm sure either vehicle will perform well in that range.

What is very impressive is that the Diesel Cayanne only weighs 4,586 lbs. I still see the Cayanne putting down some very impressive 0 - 60 times be some almost 600 lbs lighter than the MB Diesel. It has 5 more hp, and only 49 lbs of torque less....I think it will be able to scoot.






The Porsche Cayenne is a formidable SUV and, when equipped with the automaker's oil-burning mill, it's relatively fuel efficient too. Now, thanks to slew of enhancements, the diesel-powered Cayenne's fuel economy gets bumped up to around 32 miles per gallon.

The German automaker announced that the diesel-powered Cayenne has received a minor overhaul and now features a cleaner-burning diesel engine that's both more powerful and fuel efficient than before. Output has been bumped up by five ponies to 245 horsepower and Porsche claims the oil-burning SUV consumes only 7.2 liters of diesel fuel per 100 kilometers. That's 39.2 imperial miles per gallon (32.7 mpg U.S.). The added horsepower improves acceleration slightly, with the 0-62 miles per hour dash coming in at 7.6.

Engine modifications are limited to an all-new variable geometry turbocharger, a redesigned crankshaft, an increase in injection pressure and a reduction in weight. All told, Porsche's diesel mill now weighs 44 pounds less than the outgoing engine. Still, the oil-burning Cayenne tips the scales at a hefty 4,586 pounds, so 32.7 mpg seems rather impressive to us.

Thay all share the same block, but in the Porsche Diesel, it differs from the crankshaft, pistons and a Pure Porsche cylinder head.

This is one serious Porsche Diesel.

I'm more of a sedan/coupe kind of guy and if Porsche ever offered a Panamera here featuring this engine I'd be there in a heartbeat.

i believe the Panamera is available with that engine elsewhere.
Its hard for me to get over the AMC Pacer rear tho
