Porsche Panamera comes with a new engine - More
power and improved dynamic performance
A
three litre engine with an output of 300-bhp: The Porsche Panamera
Diesel has become even more attractive
Stuttgart - With its completely new 300-bhp engine and dynamic
performance package, Porsche has made the Panamera Diesel even more
attractive just in time for this year's International Motor Show (IAA).
The vehicle has once again been kitted out with a six-cylinder V-engine
with a displacement of three litres, and the power output has been
increased by 50 bhp, equivalent to a considerable 20% increase in
performance compared to the predecessor model. As a result, the
acceleration time has been reduced by eight-tenths of a second, meaning
that the new model goes from 0 to 100 km/h in 6.0 seconds, while the top
speed has increased to 259 km/h compared to the 244 km/h achieved by the
previous model. |

In addition to the improved power output,
dynamic performance has also been optimised: For instance, 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 petrol 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 (221 kW) at 4000 rpm,
the rated torque has also been increased by 100 Newton metre to 650 Nm
at engine speeds of between 1750 rpm and 2500 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 2600 kg effortlessly, meaning that it
is better able to tow attachments like horse boxes than its predecessor.
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. The Gran
Turismo with the new engine offers an NEDC fuel consumption of 6.4
litres/100 km, which is equivalent to 169 CO2/km.

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 an
impressively 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 EUR 85,300 including VAT in Germany.
