Porsche bringing diesel Cayenne to the US with 2013 MY

3 April 2012

Porsche will offer the Cayenne Diesel in the United States market for the first time beginning with the 2013 model year. The third-generation 2013 Boxster, the first all-new design since its debut in 1996, is also on display at the New York International Auto Show along with the Cayenne Diesel.

The Cayenne Diesel is powered by a 3.0-liter V6 turbo diesel engine, delivering 240 horsepower (179 kW) and 406 lb-ft (550 N·m) of torque from as low as 1,750 rpm. The result is 0-60 mph acceleration in 7.2 seconds and a top track speed of 135 mph (217 km/h). Based on preliminary internal estimates, the Cayenne Diesel SUV will achieve a rating of 20 mpg city / 28 mpg highway / 23 mpg combined (11.7, 8.4 and 10.2 L/100km, respectively) on its US EPA label. Final figures will be confirmed closer to the start of sales later in 2012.

The Cayenne Diesel meets US Tier 2 BIN5 emissions standards using selective catalytic reduction (SCR) technology. The SCR system comprises an AdBlue tank located in the car’s spare-wheel well, a heating system for this tank and the lines which carry the AdBlue, an injection valve for AdBlue fluid and a selective catalytic reduction converter, which aid in the reduction of NOx emissions.

Highlights of the 3.0-liter V6 diesel engine in the Cayenne Diesel include high pressure common rail fuel injection and a variable vane geometry turbocharger, which give the engine improved response to driver inputs and enhanced fuel economy when compared to more conventional diesel engine technologies.

In addition, the engine block is constructed from compacted graphite iron (CGI), which has many of the strength properties of a conventional iron block but with a reduction in mass of approximately 55 lbs (25 kg).

The Cayenne Diesel is mated to an 8-speed Tiptronic S transmission, without the Auto Start/Stop function available on other Cayenne variants. As with the Cayenne S Hybrid, the Cayenne Diesel includes Porsche Traction Management (PTM), which features permanent all-wheel drive.

The Cayenne Diesel also comes standard with a system to protect the driver from fueling the vehicle with the incorrect fuel. A mechanical safeguard in the fuel tank filler neck ensures that the locking mechanism can only be opened by the larger diameter diesel fuel pump nozzle and that refueling will only begin at that point.

The Cayenne Diesel is rated to tow up to 7,716 lbs. and can travel up to an estimated 740 miles on a single tank of fuel.

The newest addition to the Cayenne family in the US will go on sale in September at a base MSRP price of $55,750, not including a $975 destination charge.

Boxster. The open-top two-seater is being marketed with a completely new lightweight design body and a completely revamped chassis. Considerably lower weight, a longer wheel-base, a wider track and larger wheels significantly enhance the mid-engine sports car's driving dynamics, further supported by the new electro-mechanical power steering. The new Boxsters offer superior performance as well as being up to 15% more fuel-efficient.

The new generation debuts in the pairing of Boxster and Boxster S. Both models are powered by flat-six engines with direct gasoline injection, the efficiency of which is further enhanced by electrical system recuperation, thermal manage- ment and auto start/stop function. The entry-level model’s new power unit delivers 265 hp (195 kW) from a 2.7 liter displacement—10 hp more than its larger displacement predecessor. Technically, it is now based on the 3.4-liter engine of the Boxster S, which now delivers 315 hp (232 kW), up 5 hp than before.

At 23 mpg it is a real diesel fuel guzzler.

Why not a Boxster diesel ?

The Cayenne is a 4500lb, high performance, luxury, crossover. Diesel or not it's going to be a fuel guzzler.

Porsche puts its boxsters in its rear engined cars, the Cayenne is a front engined car like the Porsche 924 & 928.

Cayenne diesel: nice torqu-ey towing machine--haul that speedboat to the lake!

I guess we shouldnt hold much hope that a 1.9L Twin turbodiesel that produces 180hp w/400Nms @1800rpm, does 0-62 in 9secs and gets 4(55)-5.5(46) L/100km will arrive anytime soon?
