2005 Pagani Zonda F Modification Design

The Zonda C12 F debuted at the 2005 Geneva Motor Show. It is the most extensive reengineering of the Pagani car yet, though it shares much with its predecessors including the 7.3 L V12. Power is increased to 602 PS (594 hp/443 kW) with a special clubsport model producing 650 PS (641 hp/478 kW). The company promises a 3.5 second sprint to 62 mph (100 km/h), a top speed over 215 mph (346 km/h). The Zonda F clubsport has a power to weight ratio of 528 bhp/ton (384 W/kg). An Enzo Ferrari, comparatively, has a power to weight ratio of 483 bhp/ton (356 W/kg).

The top speed can be further tweaked by adjusting the aerodynamic settings. 215 mph (346 km/h) is the car’s top speed on the setting for the best handling which provides the most down force but also has the highest drag coefficient. If the aerodynamic settings were adjusted the top speed would be a bit higher. This also seems to be the reason that when EVO Magazine attempted the Pagani Zonda S’s top speed on the Autobahn, that they were only able to get the car to 197 mph (317 km/h), as opposed to its claimed top speed of 220 mph (350 km/h). It would make sense that if the car was set up for maximum downforce then its top speed would drop to around 200 mph (320 km/h). Company representatives at Pagani’s factory backed up this claim. However, the EVO article claimed that aerodynamic parts, specifically ones which created drag were in fact removed during the run, bringing Pagani’s claims into question.

2009 Nissan GT-R Introduced with More Power

2009 Nissan GT-R Introduced with More Power

Only a year after the GT-R's market launch in Japan and less than six months after its U.S. introduction and Nissan has proceeded to the sportscar's first major round of changes which include a power increase, suspension upgrades and a new exterior color. The most significant improvement concerns the GT-R's hand-built 3.8-litre V6 twin-turbo engine which has gained 5PS thanks to some fine tuning of its electronics, taking power output to 485PS, while torque remains unchanged at 588Nm.The engine upgrades have also led to slightly better fuel economy figures with Nissan announcing an average fuel consumption in the Japanese driving cycle of 8.3 km/l (19.5 mpg U.S.) instead of 8.2 km/l (19.3 mpg US). In addition, Nissan has increased the GT-R's fuel tank capacity from 71 liters to to 74 liters.
Another update sees the improvement of the sportscar's ride performance with modifications to the suspension spring rate settings while the 2009 model will also benefit from a set of Dunlop SP Sport 600 DSST tires. Nissan claims that the tire was developed specifically for the GT-R and it "combines grip and durability, as demonstrated during its 'time-attack' lap of the Nurburgring", which yielded a time of 7 minutes 29 seconds.

Less significant improvements for the 2009 GT-R concern the introduction of the Gun Metal grey colored Rays seven-spoke alloy wheel design for the standard and Premium Edition GT-Rs, while the Black Edition will be fitted with the same design but, appropriately, in black. Additionally, customers can now choose a new deep white pearl color called 'Storm' which replaces the original pearl white which had a slightly darker shade.
Last but not least Nissan has also hiked the prices for its subtly updated GT-R. In the U.K. for example, customers ordering now will have to pay £56,795 on the road for the basic version with an increase of £1300 for the Premium Edition (£58,095) and another £1300 for the Black Edition (£59,395). This represents an increase of 3.8 percent.
In Europe, the first GT-Rs are scheduled to hit dealerships in April 2009. To date, Nissan has taken in excess of 2500 customer orders in Europe with 1200 coming from the UK. Any new customer orders should expect delivery in mid 2010.
