Auto News: 2010 Porsche 911 Turbo drops 10 seconds off its Nurburgring lap time

Thursday, October 15th, 2009

There has been quite an interesting back and forth going on between the backwards engineered German sports car builder Porsche and the Japanese automaker Nissan concerning both car builder’s flagship vehicle’s time lapping a certain 12.9 mile long loop.

Nissan had announced in April that the GT-R had set a new lap record on the Nurburgring with a lap time of 7 minutes and 29 seconds back on April 17, 2008. After a bit of bad sportsmanship Nissan’s test driver piloted the GT-R around the green Hell in 7 minutes and 26 seconds on April 23rd of this year, besting the Carrera GT super car’s Nordschleif lap time of 7 minutes and 28 seconds.

After the most recent attempt at conquering the Ring, Porsche sent a 2010 911 Turbo to conquer the 73 turn race course with the hidden hope that they would be able to put a dent in the GT-R’s Nurburgring legacy. The new turbo is a much more refined performance machine coming with improved fuel economy, a lower curb weight and even more power.

Under the rear deck lid, Porsche is now using a twin turbocharged 3.8 Liter direct gasoline injected flat six engine that delivers a maximum output of 500 HP and when combined with the German automaker’s new seven speed PDK gearbox can sprint from 0 to 60 MPH in only 3.4 seconds and reach a top speed of 194 mph.

So with quicker acceleration, a higher top speed and improved chassis dynamics the new 911 Turbo had no problem shaving 10 seconds off of its previous lap time, however 7 minutes and 39 seconds is still a long ways off from the Nissan’s current record.

With a more hard core GT-R SpecV on the way, the German engineers still have their work cut out for themselves.

Auto Specification: Mazda hydrogen rotary hybrid hauler

Wednesday, October 14th, 2009

Mazda’s green-car mantle is being carried by the company’s Premacy peoplemover with its application of the hydrogen rotary hybrid formula first used in the RX-8 released in 2006.

The hatch, unlike the RX-8, offers the driving versatility for five passengers and a range up to 200km. The Premacy’s drivetrain is rated at 110kW, combining an electric motor receiving regenerative feed to drive the wheels.

It is powered with a conventional reciprocating petrol engine, the Premacy Hydrogen RE features Mazda’s trademark rotary powerplant.

Use of hydrogen fuel have the benefits, includes a relatively innocent emission in the form of water vapor.

Decades-long, Mazda’s adherence to rotary engine technology has paid off because rotaries burn hydrogen fuel more efficiently than the conventional engine.

Hydrogen is susceptible to preignition due to its flammability and due to its high temperature, it usually emanated from spark-plugs, but this is contained in a rotary engine because the design of the rotary means the combustion chamber is separated from the intake chamber.

Abnormal combustion is less in a rotary than a hydrogen-fuelled conventional reciprocating engine.

The powertrain ‘hybrid’ is termed by Mazda, as there is no electric drive, and it is more concerned about the term engine stability in order to run both hydrogen and normal ULP.

Using the dual-fuel system, Mazda’s HR engine can resort to petrol in the event hydrogen is unavailable. At this stage, without a decent number of hydrogen filling stations on offer it’s a necessary inclusion.

The Premacy also uses Mazda’s Biotech materials movement towards implementing more plant-based component materials in the use of plastics and fabrics.

In 2002, the Premacy was offered to local buyers, but remains on sale in Europe as the Mazda5. Australia-based-Mazda has no plan to introduce the Mazda5 because it believes the segment is accommodated by the CX-7 in Australia.

The government and energy agencies in Japan in March will take part in a lease agreement for use of the vehicles.
