nissan z350

                                                                                              The Nissan 350Z is a two seat sports car that was manufactured by Nissan from 2002–2009 and marks the fifth generation (codename: Z33) of Nissan's Z-car line. The 350Z entered production in late 2002 and was sold and marketed as a 2003 model. The first year there was only a coupe, as the roadster did not debut until the following year. Initially, the coupe came in base, Enthusiast, Performance, Touring and Track versions, while the roadster was limited to Enthusiast and Touring trim levels. The Track trim came with lightweight wheels and Brembo brakes, but its suspension tuning was the same as all other coupes. The Nissan 350Z has been succeeded by the 370Z for the 2009 model year.A proper sports car for the everyman. If we had just one sentence to describe the Nissan 350Z, that'd be it. While there have always been plenty of unobtainable sports cars out there to drool over, the 350Z's relatively compact dimensions, rear-wheel drive, two seats, muscular engine and sharp handling came at a price that real people could actually afford.

The Nissan 350Z represented the fifth generation of "Z" sports cars from this Japanese manufacturer. At its debut in 2003, the 350Z represented a key component of Nissan's rebirth in the North American market. For much of the late '90s and early new millennium, Nissan's lineup was full of lackluster cars. The Z brought back the company's spirit of fun and performance that had been missing ever since the discontinuation of the previous 300ZX.

The 350Z coupe was replaced by the 370Z coupe for 2009, while the 350Z roadster lived on before following suit the following year. In coupe or drop-top form, the 350Z was quite popular so finding a nice example on the used car market should be relatively easy. That said, keen shoppers will want to pay close attention to the car's changes and updates that were made through the years.

audi q7 v12 tdi

he World's Most Powerful Diesel Passenger Car

Audi has presented the world's first twelve-cylinder diesel engine in a series passenger car. This six-liter V12 makes its debut in the Audi Q7. It produces a colossal 500 bhp and 738 lb-ft of torque. With this engine Audi has opened a new chapter in diesel history.

The V12 TDI is reminiscent of the engine featured in the new R10 Le Mans racing car - it catapults the driving performance of the Audi Q7 into the echelons of top-class sports cars. The car sprints from 0 to 62 mph in just 5.5 seconds, and has an electronically governed top speed of 155 mph. Maximum torque is available from just 1,750 rpm. The high-tech diesel engine, with the world's first 29,000 psi Bosch Common Rail system, provides the high-performance Audi SUV with superior power reserves in any situation. The impressive sound of the new Audi is provided by the ultra-modern piezo-injection system. The V12 TDI transmits this power through a new six-speed tiptronic gearbox to the quattro permanent four-wheel drive system.

Although the V12 TDI belongs to the Audi V-engine family, this model features a special cylinder angle of 60° - perfect for this engine type. Apart from the light and highly durable crankcase, a further highlight is the new chain drive assembly. This includes the two newly developed high-pressure pumps in the common rail injection system.

Up to 29,000 psi of pressure is kept within the twelve piezo injectors - a further technological breakthrough. Both performance and efficiency are optimized by this high injection pressure, and the running smoothness also remains excellent. Exhaust emissions are also low. The twin-turbo V12 TDI conforms to the Euro 5 emissions class which should come into force in 2010. Combined fuel consumption is nearly 20 mpg. With the high-tech twelve-cylinder engine using TDI technology, the diesel pioneers at Audi have opened new horizons in motoring.

The Design

The Audi Q7 V12 TDI is impressive not only with regard to technology but also in terms of appearance. The most striking visual changes to the Audi Q7 are the underbody panels at the front and rear. The chrome-plated single-frame radiator grille evokes the tradition of the Audi S6 and S8. These two cars, with their V10 FSI engines, are the top sports models in their class. The V12 TDI features a powerful braking system which is every bit its equal.

There are currently no plans to import this engine to the North American market.Audi is proud to present a world first – the first twelve-cylinder diesel engine in a series passenger car. This six-litre V12 makes its debut in the Audi Q7. It produces a colossal 500 PS and 1,000 Nm of torque. With this engine Audi has opened a new chapter in diesel history.
The V12 TDI is reminiscent of the engine featured in the new R10 Le Mans racing car – it catapults the driving performance of the Audi Q7 into the echelons of top-class sports cars. The car sprints from 0 to 100 km/h in just 5.5 seconds, and has an electronically governed top speed of 250 km/h. Maximum torque is available from just 1,750 rpm. The high-tech diesel engine, with the world’s first 2,000 bar Bosch Common Rail system, provides the high-performance Audi SUV with superior power reserves in any situation.
