Various news outlets have speculated that Porsche's first-ever diesel engine would be installed in the Cayenne SUV for 2009, and now Porsche CEO Wendelin Wiedeking has confirmed it. As previously reported, the oil-burner will be snatched from the Audi parts bin and reportedly be essentially unchanged in Porsche guise. That means 240 horsepower and 406 lb.-ft. of torque, plenty to get the hefty Cayenne out of its own way. Instead of spending development money on a Porsche-specific diesel engine, Zuffenhausen has instead invested in a hybrid system, which will also see duty in the Cayenne around 2010. By then, a lithium-ion battery will likely be ready to replace the prototype's nickel-based unit.
What do Porsche and Lamborghini have in common? Well, a lot. To begin with, both make highly desirable sports cars, and after the former bought up a serious stake in Volkswagen, which in turn had bought the latter, both are now under common ownership. Both have produced insanely powerful sport-utilities and both have built tractors. Lamborghini started out making tractors before Ferruccio's infamous run-in with Enzo Ferrari, after which he started making sportscars. The rest, as they say, is history. Porsche, on the other hand, started out in the opposite direction, producing sportscars before eventually moving on to sport-utes. But back in the 1950's, Porsche made a series of tractors as well. Now one enthusiast has brought it around full swing with this unique Porsche tractor.
The machine started out as a 14.5hp Partner lawn mower before its owner went to town, taking apart the engine and painting it yellow, fitting a custom stainless-steel exhaust, a fire extinguisher and a tachometer crafted from a 911 oil filter, then painting the body "Grand Prix Weiss" with "Idischrot" red accents. The result? Well, it won't be setting any Nürburgring lap records, but we'd be happy to see it face off against an old Porsche Diesel Super tractor to see which could mow The Green Hell fastest.
