Rollover sensor: even greater passive safety
|
Cayenne TurboThe new Porsche Cayenne Turbo remains the top performer in the sports utility market: biturbo technology, direct fuel injection and VarioCam Plus valve management give the new 4.8-litre power unit maximum torque of 700 Newtonmetres or 516 lb-ft maintained con-sistently all the way from 2250 to 4500 rpm.
Dynamic headlights featured as standard Behind the newly designed clear glass covers, the Cayenne Turbo boasts bi-xenon headlights as standard featuring both static and, for the first time, dynamic headlight beam control. The bi-xenon headlight unit is split up into three sections, with the swivelling xenon unit at the outside, the static bend lights in the middle, and the additional high-beam headlights at the inside. The dynamic headlight beam function is activated as of a speed of 3 km/h, swivelling "into" the bend at an angle of 15°. The static bend light also featured on the Cayenne Turbo ensures even better illumination of the road directly in front of the vehicle, offering a significant advantage, for example, when bending into a side road. Reinforced automatic transmission featured as standard The Cayenne Turbo comes as standard with six-speed Tiptronic S automatic transmission. Taking the increase in power into account, Porsche's engineers have increased both gearshift pressure and the number of clutch plates, improving the transmission of drive forces and providing an even faster and smoother gearshift. The bearings on the planetary gearsets have also been reinforced. The automatic transmission also comes with a Hill Holder function automatically preventing the vehicle from rolling back when setting off uphill on a gradient. Fuel economy is enhanced not only by the longer final drive ratio, but also by disconnection of the transmission whenever the vehicle comes to a stop, Tiptronic S automatically shifting to neutral as soon as the driver presses down the footbrake with the vehicle at a standstill on an even surface. A new Sports Button enables the driver to additionally "pep up" the driving characteristics of the Cayenne Turbo: With the Sports Button activated, the engine is even more responsive, responding even more directly and firmly to load change commands. In the Sports mode the Cayenne Turbo always sets off in first gear and maintains even more sporting gearshift points, shifting up later and down earlier. Pressing the Sports Button, the driver automatically also operates PASM Porsche Active Suspension Management with air suspension featured as standard in the Cayenne Turbo as well as the optionally available PDCC Porsche Dynamic Chassis Control, setting both of these systems to a more sporting mode. Air suspension and self-levelling also in combination with PDCC The new Cayenne Turbo comes as standard with air suspension including PASM Porsche Active Suspension Management. Air suspension gives the driver the option to raise or lower the entire body of the Cayenne Turbo, depending on current requirements. Integrated self-levelling, in turn, serves to keep the vehicle at the same, consistent ride height at all times, regardless of load conditions. A further function is the automatic reduction of ride height at increasing speed, enhancing active safety and reducing fuel consumption in the process. Variable PASM Porsche Active Suspension Management also gives the driver the option to adjust the dampers to his or her personal requirements while driving, benefiting from the choice of three programs: Comfort, Normal, and Sports. Introducing PDCC Porsche Dynamic Chassis Control, Porsche's engineers now offer a new, active suspension system ideally supplementing both air suspension and PASM. PDCC comes as an option in the Cayenne Turbo, serving to control body roll in bends and, indeed, almost entirely preventing body roll in nearly all situations. The result is an improvement of driving agility, dynamics, motoring comfort, and driving stability at high speeds. PDCC offers additional customer benefits in rough terrain: Through active control of the anti-rollbars in conjunction with integrated road surface detection, excitation of the body is significantly reduced and motoring comfort enhanced accordingly. In the offroad mode the system furthermore allows maximum axle articulation at speeds of up to 35 km/h or 22 mph. High-traction PTM and enhanced PSM PTM Porsche Traction Management permanent all-wheel drive gives the Cayenne Turbo outstanding on-road and off-road driving characteristics at all times. In its basic mode, the system shares out engine power front-to-rear at a ratio of 38:62, with potentially up to 100 per cent of engine power being fed to either the front or the rear wheels, if required. In addition, PTM enables the driver to keep the vehicle under control in a smoother, superior style when driving to the limit, for example on snow and ice. PTM Porsche Traction Management permanent all-wheel drive constantly communicates with PSM Porsche Stability Management, the latter masterminding essential systems such as ABS, ASR Anti Slip-Control and ABD Automatic Brake Differential, but only intervening under extreme physical conditions in the interest of a sporting style of motoring at all times. As a function of driving conditions and requirements, the new pre-loading brake function and the Brake Assistant serve to minimise stopping distances by building up full brake pressure as quickly as possible. New offroad-ABS, in turn, recognises loose ground beneath the vehicle and applies the brakes with an optimised strategy, building up an additional brake "wedge" in front of the wheels. And whenever the vehicle is towing a trailer, PSM detects any possible pendulum or sway action and stabilises the vehicle and trailer by inter-vening as required in the brakes on both sides. Superior safety thanks to high-performance brakes The brake system on the new Cayenne Turbo stands out clearly not only through its red callipers. For to cope with the significant increase in engine output, the entire brake system has been upgraded with enhanced power assistance. Diameter of the brake discs is up on the front axle from 350 to 368 millimetres (14.49") and at the rear from 330 to 358 milli-metres (14.09"). The correspondingly larger brake callipers at the front incorporate an additional reinforcement frame bolted at four points to the calliper housing and serving to reinforce the entire brake structure. To reliably dissipate the high temperatures generated while applying the brakes also under high loads, additional brake air spoilers on the front spring struts guide cooling air to the discs. Given all these improvements, the new brake system once again enhances fading stability and, as a result, lasting brake qualities over the former model by some 10 per cent. Special 18-, 19- and 20-inch wheels have been developed for the Cayenne Turbo, taking all lightweight construction principles into account. The wheels are manufactured through the flow-forming method with the rim hump being rolled out extra-thin, reducing the weight of each wheel by 1.0 - 1.5 kg. The new Cayenne Turbo comes as standard on 8J x 18 wheels in Turbo design combined with 255/55 R18 tyres. Porsche has indeed commissioned the development of a brand-new family of tyres for the Turbo wheels naturally tested in full for their highspeed qualities. As a result, the Cayenne Turbo runs on Y-rated summer tyres approved for a top speed of 300 km/h (186 mph). New rollover sensor and intelligent tailgate Like the other models in the Cayenne range, the Cayenne Turbo naturally offers its occu-pants a comprehensive restraint system. Apart from three-point safety belts, belt latch tensioners and belt force limiters, this also means a full-size airbag for the driver and front passenger as well as a side protection system with thorax airbags and curtain airbags integrated in the roof frame. A new yaw rate sensor activates the curtain airbags and belt latch tensioners also in the event of a rollover.

Looking at the competition, this is
more than even significantly larger gasoline engines have to offer. The result
is acceleration to 100 km/h in the top-level Cayenne within just 5.1 seconds,
maximum output of 500 bhp or 368 kW interacting with exemplary aerodynamics
(Cd = 0.35) to give Porsche's most powerful Sports Utility a top speed of
275 km/h or 171 mph - an unparalleled figure in this segment. Benefiting
from this extra power and enhanced streamlining, the top-end Cayenne is half
a second faster to 100 km/h and offers a maximum speed up yet again by 9
km/h or 5 mph. Despite this significant improvement of performance, fuel
consumption under reallife driving conditions is down by up to 15 per cent.
