My Dream Car

Porsche 911 turboSince I have played the game Need For Speed Porsche, I have loved that car porsche 911! The Everyday Supercar: Porsche 911 Turbo The 2007 911 Turbo may be unmatched in its breadth of performance. Few machines can so easily warp our perception of what is possible from a state-of-the-art performance car, and yet so ably serve as a practical and comfortable conveyance for every-day driving. The new Porsche 911 Turbo features a revolutionary 480-horsepower, twin-turbocharged, 3.6-liter boxer engine with the world’s first gasoline-engine application of variable turbine geometry (VTG), a redesigned all-wheel-drive system, and evolutionary styling.

The new 911 Turbo’s engine produces 480 hp at 6,000 rpm, 60 bhp more than its predecessor, raising specific output of the 3.6-liter boxer-Six to an all-time high of 133 bhp per liter. More notable is the engine’s torque curve, which has been bolstered and broadened by the variable turbine geometry system. Peak torque rises to 457 lb-ft (previously 415 lb-ft), but that peak now spans an extended rpm range from 1,950 to 5,000 rpm, compared to 2,700--4,600 rpm in the previous 911 Turbo. Additionally, a function in the optional Sport Chrono Package allows a 10-second, mid-rpm-range ‘overboost’, temporarily increasing turbo boost under full throttle by 2.9 psi, and swelling peak torque to 502 lb-ft.

A 911 Turbo equipped with the optional 5-speed Tiptronic S automatic transmission requires only 3.4 seconds to sprint from 0 to 60 mph. Equipped with the standard six-speed manual transmission, the new 911 Turbo reaches the same 60 mph mark in 3.7 seconds. With either gearbox, the top track speed of the new 911 Turbo is 193 mph.

Much of the 911 Turbo’s improved performance can be attributed to the variable turbine geometry system, the first such system available on a turbocharged gasoline engine. The heart of the technology is adjustable guide blades, which can vary in angle to most effectively guide engine exhaust flow onto the turbocharger’s impeller wheel. The result is a system that provides the advantages of both a small and large turbocharger, improving flexibility and acceleration, particularly at low engine speeds.

To transfer this power to the road, the new 911 Turbo features a redesigned all-wheel-drive system, with an electronically controlled multi-disc clutch replacing the previous model’s viscous clutch. Porsche Traction Management (PTM) allows variable power distribution fore and aft, and depending on conditions, the system’s electronics constantly determine optimal torque distribution to ensure ideal traction. In use, PTM provides exceptional agility on winding roads, outstanding traction in inclement conditions, and impressive active safety even at higher speeds. Though powerful, the 911 Turbo’s PTM setup is one of the lightest all-wheel-drive systems on the market.

The new 911 Turbo’s accelerative performance is duly tempered by its brake system, which is comprised of six-piston monobloc calipers up front, and four-piston monobloc calipers at the rear. Brake disc diameter at all four corners has been increased 20 mm, to 350 mm (13.78 in.). Optional is Porsche’s Ceramic Composite Brake system (PCCB). In addition to the exotic pad and rotor material, the PCCB option provides an increased front disc diameter (380 mm /14.96 in.), absolute corrosion resistance, improved fade stability, and a 37-pound unsprung-weight savings versus the standard brake system.

Styling changes made to the new 911 Turbo are evolutionary. The modified front end features tautly drawn cooling air inlets, widely spaced and deep-set fog lights, and new LED indicators situated in the lateral air inlets. From the rear, the Turbo takes on a more powerful stance thanks to a tail 22 mm (0.9-in.) wider than that of the previous model. The redesigned wing spoiler has been aligned to the wider profile, and slopes downward slightly at each end to nestle the rear fender’s contours. The lateral air inlets behind the doors have also been redrawn, and together with the new air ducts, afford a more efficient supply of cooling air to the intercoolers.

 

I love off-road driving even more, so the Porsche cayenne comes in. The 2008 Porsche Cayenne Turbo - Aggressive Styling Supported by 500 Horsepower.

With a striking new face that features a dramatic new headlight design and with a wide and muscular body accented by broad wheel arches, the 2008 Porsche Cayenne’s newly sculpted shape
provides vivid visual testimony to the vehicle’s enhanced technical features.

The 2008 model year marks the launch of the second generation of the Porsche SUV, and the new Cayennes back up their aggressive new design with larger and more powerful – but also more fuel-efficient engines.

As you would expect from Porsche, the new Cayenne Turbo not only looks more powerful, it is, with the engine offering 500 horsepower and new dynamic technologies that allow the Porsche of SUVs to perform more like a more nimble vehicle, yet still be capable of towing a trailer or challenging unpaved terrain and inclement weather.

The 2008 Porsche Cayenne Turbo features a twin-turbocharged 4.8-liter V8 that pumps out an astounding 500 horsepower and 516 pound-feet of torque. Flowing through a six-speed Tiptronic S transmission, that power feeds all four wheels and propels the five-passenger sports machine from a standing start to 60 miles per hour in just 4.9 seconds. Top speed on the test track has been recorded at 171 mph. And yet, the Cayenne Turbo qualifies as an LEVII (low-emission vehicle) and in preliminary fuel economy testing the Cayenne Turbo showed the benefits of the direct fuel injection technology with an improvement up to 11 percent in highway driving.

Direct fuel injection is only one of the new technologies featured on the 2008 Porsche Cayenne Turbo. For example, for the first time the Cayenne V8 engines also are equipped with Porsche VarioCam Plus variable valve control.

The second generation SUVs can be equipped with Porsche Dynamic Chassis Control (PDCC) that includes active anti-roll bars that almost completely offset body roll in turns, improving handling, comfort and safety on road while also providing enhanced traction off pavement.

New as well are Dynamic Curve Lights (standard on the Cayenne Turbo and optional on the other models) to enhance the driver’s view at night on a curving roads.

Standard equipment on all versions of the 2008 Cayenne includes Porsche Stability Management (PSM), now with new functions such as pre-loading of the braking system when needed, new Trailer Stability Control and off-road ABS.

For the first time, the Cayennes come with a rollover sensor able in an emergency to trigger both the belt latch tensioners and curtain airbags, thus helping to reduce the risk of injury for all occupants in a rollover. In conjunction with the Cayenne’s six standard airbags, this system gives Porsche's sport utility a benchmark occupant safety and protection system.

Other new features include a standard and push-button Sports mode for all Cayenne engines, a standard power rear lift gate, the availability of 21-inch wheels, a rail-mounted cargo management system and XM satellite radio.

As in China, buying such cars could cost you a lot. whatever you do bisides business you can affort that cost. I got pretty jealousy about the citizen of the U.S. because of the states was low density populated, everybody would have to hop-in to a car a do what's have to be done. It's a tool of everyday life, not a luxury goods as in China.
