Porsche R&D chief Wolfgang Hatz hints at a diesel-powered Boxster

Article by Christian A., on May 8, 2012

Electric vehicles are not included in Porsche’s current strategy, prompting many observers to ask what the holdup is. Porsche R&D chief Wolfgang Hatz, who was at the 33rd Vienna Motor Symposium, had talked about diesel powerplants but said that pure electric vehicles are “not even close to series production with the current battery technology.”

This contradicts Porsche’s previous statement about testing the electric Boxster prototypes. It’s likely that Porsche isn’t satisfied with the results.

Hatz said that internal combustion engines will continue to dominate in the foreseeable future and that the diesel is a firm part of the VW Group’s current strategy.

Hatz said that what’s more important is that the company will offer variants that are more powerful. He added that it would be a mistake to refuse a Boxster diesel “for all times.”

This makes people wonder what Porsche’s diesel car strategy might be. First, there’s the conventional fuel economy and budget-minded direction. Porsche may consider diesels as a performance option, similar to how BMW has presented a new range of M line performance diesels.

In addition to displaying exceptional performance, the new Boxster from Porsche is also fuel efficient. In fact, it is 15% better compared to the previous version. All of the new versions will have the six-cylinder direct-injection ultra-modern engine with all variants as well have fuel efficiency not exceeding 9 liters per 100 kilometers. For the Boxster that comes with the Porsche-Doppelkupplungsgetriebe, or PDK, fuel efficiency is even below 8 liters.

In terms of actual figures, the Boxster has the 2.7-liter boxer engine capable of 265 hp (195 kW). It comes with a rear-wheel drive and is paired to the manual six-speed transmission as standard though the seven-speed PDK is offered as an option. Under the manual transmission, acceleration from 0 km/h to 100 km/h is possible in 5.8 seconds. Using the PDK, the time is lowered to 5.7 seconds. Meanwhile, the Sport Chrono Package brings this down even further to 5.5 seconds.

With the manual transmission, maximum speed is at 264 km/h with fuel consumption under the New European Driving Cycle (NEDC) of 8.2 1/100 km and CO2 emissions measured to be 192 g/km.

Using the PDK transmission, top speed is 262 km/h with NEDC fuel consumption of 7.7 1/100 km and CO2 emissions of 180 g/km. Meanwhile the Boxster S has the 3.4-litre boxer engine with output at 315 hp (232 kW). Rear-wheel drive is also included and has the same transmissions as that of the base model. Acceleration from 0 to 100 km/h is attained in 5.1 seconds with maximum speed of 279 km/h. NEDC fuel consumption has been measured to be 8.8 1/100 km with CO2 emissions of 206 g/km. Note that this is under the manual transmission as the PDK transmission shows improved figures like with the Boxster.

Acceleration is achieved in 5.50 seconds with a top speed of 277 km/h. NEDC fuel consumption meanwhile is 8.8 1/100 km with CO2 emissions of 188 g/km. For those who avail of the Sport Chrono Package, acceleration is improved further as it takes only 4.8 seconds to go from standstill to 100 km/h. In addition to being more fuel efficient, the new Boxster is comparably lighter as well as showing more agility and being faster.

With a chassis that has been totally overhauled and paired with a body that has a lightweight design, it is no wonder that this latest generation of the Boxster is getting top marks when it comes to the Porsche Intelligent Performance. With a mid-engine configuration, this already means that the driving dynamics is excellent. However, the combination of the larger wheels, wider track, longer wheelbase, and low weight further increase the driving dynamics.

By having an electro-mechanical power steering, this allows the new Boxster to lead even further over other models in the same class. As shown earlier, the Sport Chrono Package helps increase the driving dynamics and this is offered by Porsche to customers as an option. It comes with dynamic transmission mounts, a first for the brand. New as well under this package is the Porsche Torque Vectoring, or PTV, that comes with mechanical rear axle differential lock.
