New 300 hp 3.0L V6 diesel for Porsche Panamera boosts power by 20%, small improvement in fuel consumption

Porsche is introducing a new 300 bhp (221 kW) 3.0L diesel in its Panamera Diesel. The six-cylinder V-engine increases power output by 50 bhp—equivalent to a 20% increase in performance—compared to the predecessor model. The Gran Turismo with the new engine offers NEDC fuel consumption of 6.4 liters/100 km (36.8 mpgUS)—equivalent to 169 CO2/km—a small improvement on the 6.5 l/100 km (36 mpg US) of the standard earlier 250 hp model. That model delivered 6.3 l/100 km (37.3 mpgUS) with optional low rolling resistance tires. (Earlier post.)

Acceleration time for the new Panamera diesel has been reduced by eight-tenths of a second—the new model moves from 0 to 100 km/h in 6.0 seconds, while the top speed has increased to 259 km/h (161 mph) compared to the 244 km/h (152 mph) achieved by the previous model.

In addition to the improved power output, dynamic performance has also been optimized. The Panamera Diesel now features the controlled rear-axle differential lock with Porsche Torque Vectoring Plus (PTV+) as standard for the first time; to date, this feature has been reserved for the gasoline engine Gran Turismo models.

The transmission and chassis have also been retuned. Around 8,500 Panamera Diesel vehicles have been delivered so far, and the model accounts for a share of around 15% of the complete Panamera model range.

The only aspect that still remains of the previous Panamera Diesel’s V6 engine are the basic engine dimensions. The moving parts in particular, such as the crankshaft drive and pistons, have been completely re-designed and dimensioned with the aim of increasing the power output.

Porsche has combined its new engine with a water-cooled turbocharger for the first time, too. The new turbine provides a greater air flow as well as a higher boost pressure of 3 bar (formerly 2.5 bar).

In addition to the increased power output of 300 bhp at 4,000 rpm, the rated torque has also been increased by 100 N·m to 650 N·m (479 lb-ft) at engine speeds of between 1,750 rpm and 2,500 rpm, providing even greater power at lower speeds.

This power needs to be reliably converted into traction, which is where PTV+ comes in: The system comprises an electronically controlled, fully variable rear-axle differential lock and targeted, individual brake interventions at the rear wheels. At low to moderate speeds, the PTV Plus improves agility and steering precision; at high speeds and when accelerating out of bends, it delivers greater driving stability. As a result, the Panamera Diesel can now handle trailer loads of up to 2,600 kg (5,700 lbs), meaning that it is better able to tow attachments such as horse trailers than its predecessor, Porsche suggests.

The more powerful characteristics of the turbo engine also offered an opportunity to re-tune the transmission. In order to reduce fuel consumption and improve comfort at higher speeds in particular, the gear ratio is longer for the rear axle, meaning the Panamera Diesel uses a lower engine speed to achieve the required vehicle speed.

In addition, gears one to four of the eight-speed Tiptronic S transmission have been designed with a shorter gear ratio, giving the Gran Turismo powerful acceleration and sprint capability. This improved agility is also evident in the running-gear set-up: The anti-roll bars on the front and rear axle are slightly more rigid, giving the Panamera Diesel a sportier feel than its predecessor.

The Panamera Diesel with the new engine replaces the current 250-bhp variant and will be available on the market from January 2014 onwards. The vehicle costs €85,300 (US$113,000) including VAT in Germany.



It had escaped my attention that Porsche even sold diesels.  It has stellar performance and achieves almost the fuel economy of the diesel Passat of ten years ago.  Color me impressed.


OK EP, but the Passat is a bit cheaper.
It is nice to see people like Porsche thinking about economy as well as pure speed.
(I would have felt 161 mph would be enough for most people).
More useful to have a car which could cruise at 120 mpg for ages, but not possible in many countries, or places within those places.


It screams, it tows, and it still gets 36 MPG highway.  That is a raised middle finger to those who say it cannot be done.  There are no more excuses.


In the 60´s, our neighbour had a Porsche diesel. I think it was the “Standard” model with a 2-cylinder air-cooled diesel engine at 20-22 hp. Porsche also had 3 and 4-cylinder models, as well as a single-cylinder model. Compared to the Standard model our neighbour had, the 3-4 cylinder engines must have felt very powerful.


I'm sure that was just the thing to drive on dates in college.  A real panty-dropper.


Dude, didn't you know Porsche was a part of the Volkswagen Group? They sell passenger cars under the Audi, Bentley, Bugatti, Lamborghini, Porsche, SEAT, Škoda and Volkswagen marques; motorcycles under the Ducati brand; and commercial vehicles under the MAN, Scania and Volkswagen Commercial Vehicles marques. The multinational is divided into two primary divisions, the Automotive Division and the Financial Services Division, and consists of approximately 340 subsidiary companies. The company has operations in approximately 150 countries and operates 100 production facilities across 27 countries. It holds a 19.9% non-controlling shareholding in Suzuki and has two major joint-ventures in China: FAW-Volkswagen and Shanghai Volkswagen.

OF COURSE they sell diesels!


My involvement with Volkswagens has been limited to little more than owning three of them.  There's also the detail that Porsche's offerings in the USA, like Mercedes', are skewed toward the sport/luxury market.  Finding a diesel 4-door sedan in the showroom next to the turbo 911 and 928 was once unthinkable.  Well... times change.
