The Porsche Cayenne Diesel was officially introduced today in the United States and easily became one of the most fuel-efficient SUVs in Porsche’s lineup. As expected, the 2013 Cayenne Diesel is powered by Audi’s 3.0-liter V6 turbo diesel engine capable to deliver 240-hp and 406 lb.-ft. of torque, available from as low as 1,750 rpm.
With these numbers, the Cayenne is able to hit 60 mph (96 km/h) in 7.2 seconds and has a top speed of 135 mph or 217 km/h. Moreover, the 2013 Porsche Cayenne Diesel has an estimated fuel consumption of 20 mpg city / 28 mpg highway / 23 combined. This means that the Cayenne Diesel will be able to travel up to 740 miles on a single tank of fuel.
Final figures will be confirmed closer to the start of sales later in 2012. According to Porsche, the Cayenne Diesel is built to meet the Tier 2 Bin 5 emission standards, and includes selective catalytic reduction (SCR) technology.
For those folks who don’t know, the SCR system is comprised of 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 used for the reduction of NOx (oxides of nitrogen) emissions. The diesel engine is mated to an 8-speed Tiptronic S transmission and doesn’t feature the Auto Start/Stop function available on other Cayenne variants.
Just like the Cayenne S Hybrid, the Cayenne Diesel includes Porsche Traction Management (PTM), which features permanent all-wheel drive. Some of the standard features found on the Cayenne Diesel is a system which protects 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 Porsche Cayenne Diesel has a base MSRP price of $55,750, not including a $975 destination charge.
New Porsche Cayenne is more efficient and more dynamic, has a more spacious interior, and is, overall, more lightweight. It points to the future of technology, as well as the future in sporting, elegant design.
The new generation of Cayenne models – led by the Cayenne S Hybrid, which is Porsche’s first production car with hybrid drive – set the benchmarks when it comes to modern efficiency, with 23% less fuel consumption than the earlier models.
And just like every Porsche product, the new Cayenne was developed in conjunction with the brand’s principle of Intelligent Performance. Porsche Intelligent Performance promotes more power with less fuel, lower CO2 emissions, and greater efficiency.
It is also worth noting that three out of five Cayenne models remain below the New European Driving Cycle’s 10-liter fuel consumption limit per 100 km. Two models – Cayenne S Hybrid at 193 g/km and Cayenne Diesel at 195 g/km – also remain below the 200-gram-per-kilometer CO2 emission limit.
This significant decrease in fuel consumption levels throughout the entire Porsche Cayenne range results, partly, from the company’s introduction of new 8-speed Tiptronic S automatic transmission with Auto Start Stop function and from a broader range of gear increments, recuperation of on-board network, thermal management on the engine and on the transmission cooling circuit, variable overrun cut-off, intelligent lightweight construction, and consistent decrease in weight.
