| Saab Turbo X touches down in Australia |
|
Turbo X was unveiled for the first time last month at the Frankfurt International Motor Show exactly 30 years after Saab revealed its first turbocharged vehicle at the Frankfurt show. Today Turbo X is more than a celebration of Saab's leadership in turbocharging - it sets new performance standards for the Swedish brand. The styling of the black limited edition model takes Saab 'back to the future' by evoking the iconic appeal of its first black 900 Turbo and introduces innovative Saab XWD (cross-wheel drive) technology to Saab Sport Sedan and SportCombi models. Thirty Turbo X vehicles have been secured for Saab customers in Australia, with 25 Sport Sedans and five SportCombi vehicles due to arrive around June next year. Pricing and full specification details of the Australian models will be made available in the coming months, and its recommended prospective customers register their interest with Saab Australia to secure a vehicle. Turbo X generates 400Nm of torque from its 206kW 2.8V6 turbo engine and introduces the latest generation AWD technology, Saab's XWD system. Saab XWD features active management that not only splits torque delivery between both axles, but also between the rear wheels. This responsive system delivers a level of driver involvement and dynamic chassis control never seen before from Saab. In addition to tuning the suspension, electronic chassis, throttle and powertrain settings, Turbo X features distinctive styling additions that enhance aerodynamic performance. Saab XWD System The Saab Turbo X adds a new dimension in chassis control to Saab's unrivalled experience in turbocharging. It is the result of a development program that leverages the full potential of Saab's innovative XWD system, with the car's sports tuned suspension, brakes and electronic control systems all aligned to meet a single need: driving satisfaction. Saab XWD is an active all-wheel-drive system designed to optimize vehicle handling and stability. (Refer to New Saab 9-3 release for full technical description). Its sophisticated electronic control allows fine balancing of drive torque, not only between the two axles but also between the rear wheels. In effect, this stretches the performance envelope of the chassis, for example, raising the threshold at which ESP throttle and braking interventions are triggered. The result is closer driver involvement through 'positive force' chassis control. The driving benefits of the XWD system are best appreciated out on the open road. Data from the ABS/ESP sensors - measuring wheel speed, yaw rate and steering angle - is utilised by the Saab XWD control module. Rear drive is instantly applied to balance oversteer and understeer characteristics, improving stability and roadholding. Driver control is taken a step further on the Turbo X by the eLSD, the first application of an electronically-controlled, rear limited slip differential in this segment of the market. It uses inputs from the rear wheel speed sensors and can transfer up to 40 per cent of torque between the drive shafts, to whichever wheel has more grip. When cornering hard, this yaw damping effect helps the rear of the car more closely follow the direction of the front wheels. To exploit the full benefits of Saab XWD, the chassis of the Turbo X has been lowered by 10 mm and the springs and dampers stiffened to minimize body movement. To maintain a constant ride height irrespective of load, self-levelling dampers are fitted at the rear. Stopping power is also increased with larger brake discs fitted: internally ventilated (345 mm diameter x 30 mm) at the front and externally ventilated (292 mm diameter x 20 mm) at the rear. Standard 235/45 R-18 tyres ensure excellent mechanical grip for the 18-inch alloy wheels. The powerhouse at the heart of the Turbo X is a 24-valve, 2.8-liter V6 turbo engine generating 400Nm of torque between 2,150 and 4,500rpm and maximum power of 206kW at 5,500rpm. The advanced specification includes a lightweight, all-aluminium construction with a 60-degree angle between the cylinder banks for perfect balance, variable inlet valve timing and twin-scroll turbocharging. It is offered with a choice of six-speed manual or six-speed automatic transmission. This responsive, high torque powerplant is the perfect partner for Saab XWD. Together, they give the Saab Turbo X sporty, all-wheel-drive performance and handling characteristics that will appeal to all enthusiastic drivers who seek a rewarding experience behind the wheel. Saab Black Turbo Reborn The Saab Turbo X visually communicates its focus on driving performance by extending the bold, progressive design themes of the new 9-3 range. Offered only in metallic jet black, with the front grille and all exterior detailing accented in a matte grey titanium-like finish, it represents a contemporary expression of its illustrious black 900 Turbo ancestor. Distinctive styling additions are designed to improve aerodynamic efficiency, as well as emphasize the Turbo X's performance focus. At the front, a deeper lip spoiler and integrated air intake contribute to reduced drag while also increasing air flow to the engine and intercooler. At the rear, the re-profiled bumper and insert panel lowers the point of air flow separation, further reducing drag and assisting high speed stability. The Sport Sedan features a rear spoiler that extends the line of the trunk deck, reducing high speed lift forces at the rear axle. The standard SportCombi already has a similar spoiler that extends the rear roof line. The Turbo X is further distinguished by unique, 18-inch alloy wheels (19-inch available as an option) with a grey titanium-like finish that evokes the look of Saab's classic three-spoke design. Twin, rhomboid-shaped tailpipes complete the exterior additions. Inside, the 'black turbo' theme is continued throughout the cabin. The sports seating, with additional bolstering, is upholstered entirely in black leather. The sporty ambience is further emphasized by a carbon-fibre finish to the main fascia, door inserts, glove box and gear shift console which is unique to the Turbo X. The driver benefits from improved 'feel' through the addition of a thick-rimmed, soft grip leather steering wheel. Seating comfort can be taken a step further with an optional premium, natural leather interior, which includes perforated bolsters for the front seat squabs and backs. In recognition of Saab's turbo heritage, the Turbo X boost gauge is a replica of the original 900 Turbo display. Owners will also enjoy a personalised greeting when they get behind the wheel and switch on the ignition. A unique 'Ready For Take-off' message flashes in the main instrument display. The owner's name, with the edition number of the car, can also be programmed for display by the supplying dealer.

Fuel consumption (combined cycle, L/100km): (data not yet available) 30 Years of Saab TurbochargingHow Saab Led the Turbo ChargeThe idea that 'less is more' is intrinsic to the minimalist tradition of good Scandinavian design. Decoration and ornate detail can sometimes distract from an appreciation of form, line or shape. While this Scandinavian perspective is very much part of Saab car design, the 'less is more' philosophy can be even more closely identified with Saab's mastery of the art of turbocharging.It was Saab who put turbocharging on the automotive map. It all began exactly 30 years ago when the first Saab turbo model was revealed at the Frankfurt Show. At that time Saab was alone in pursuing turbocharging as a reliable and realistic means of extracting more power and efficiency from a production engine. Saab's success over the next three decades shows that imitation is, indeed, the sincerest form of flattery, because there are few manufacturers who do not now offer turbocharged models.That's because the attractions of turbocharging are even more seductive today than they were three decades ago. It is the key to what Saab calls 'rightsizing'. Less is more. A turbocharged engine is lighter, smaller and more fuel efficient than a non-turbo, 'naturally-aspirated' engine capable of producing similar power. Not only that. A turbocharger develops more power by harnessing the energy from an engine's exhaust gas flow. The idea of, in effect, recycling energy that's otherwise wasted is even more compelling.Something for NothingWhile engineers will tell you that 'getting something for nothing' is not a realistic expectation in engine design, most will agree that about 30 per cent of the energy released when an engine burns fuel goes down the tube, or, in this case, the exhaust pipe. A turbocharger uses that energy to force more air into the engine. Of course, some more fuel has to be added when extra air is pumped in, but a turbo gives the driver a choice in the matter.As Saab's leading expert, Dr Per Gillbrand, often known as the 'father of the production turbo', used to say: a turbocharged powerplant is really 'two engines in one.' There is a 'small' engine for driving in everyday traffic conditions and then a 'large' one, giving more power and performance, when the turbocharger joins the party at higher throttle openings.Today, Saab remains at the forefront of turbocharging technology. In a world seeking to reduce CO2 emissions from fossil fuels, Saab BioPower engines bring together turbocharging and bioethanol (E85) fuel to drastically reduce those emissions - while also producing more power than is possible with gasoline. A smart, win/win solution.Back at Frankfurt in 1977, the sceptics were more concerned about turbocharging being a winning solution in terms of just power. Early attempts at controlling boost pressure had produced severe reliability issues that discouraged other manufacturers from further development for road-going production cars.But Saab, driven forward by the independent mind-set of its engineers and executives, remained convinced that it could be done. The company was able to draw on experience from aircraft design, where turbochargers were commonly used in aero engines to compensate for the effects of thin air at altitude. It also shared knowledge with colleagues in what was then the company's truck division, who were using turbochargers with large, heavy-duty diesel engines.Challenging Conventional WisdomSaab developed technology to 'tame the turbo' by using a by-pass valve to control the build-up of boost pressure. It did not take long for the world to appreciate what had been achieved. Fitting a turbocharger to the 2-litre engine of a Saab 99 gave 23 per cent more maximum horse power and a massive 45 per cent increase in torque, the engine's pulling power under acceleration. To produce similar power ratings, a naturally-aspirated engine of the time would have been up to 50 per cent larger in capacity and about 50 kilos heavier, with overall fuel consumption 30 per cent worse. Saab has changed conventional wisdom that equated engine power with engine size.An early Saab 99 Turbo road test in the UK's influential Autocar magazine concluded: "It is not just its performance, but the way it delivers it. Its acceleration pattern is unique. Like a roller coaster running downhill, the Saab just gets faster as the turbocharger boost increases. It's uncanny." The age of the turbo had arrived and, during the next decade, black Saab 99 and 900 Turbo models were to become defining images for the Saab brand.Over the years, Saab has continued to refine the art of turbocharging. The roller coaster is still there, but the ride is a bit more comfortable. Advances in engine management systems and turbocharger design have given today's Saab turbo engines a much smoother and more progressive power delivery. The new Turbo X, for example, delivers exceptionally strong pulling power of 400 Nm from very low engine revs, the characteristics of a far larger engine.RightsizingTurbocharging has led Saab 2,650 metres up in the American Rockies to demonstrate how its turbo cars can still perform in the thin air of altitude. And down at sea level, it has given the 9000 Aero model faster in-gear acceleration than a Ferrari Testarossa. There is even a satisfied Saab 900 Turbo owner who has clocked up more than one million miles.As long ago as 1992, Saab was able to demonstrate the abilities of its Trionic engine management system (Generation 8 is used today) by arranging an independent car test in City of London traffic. It showed that levels of regulated pollutants in the Saab's exhaust were actually lower than found in the surrounding atmosphere. The car was 'cleaning' the urban air!Today, in an era when the desire to save energy and achieve greater efficiency has never been greater, the future of Saab turbocharging has never been brighter.'Rightsizing' is how Saab describes the process of making engines more efficient, of reducing their size, weight and environmental impact without losing performance, showing that less is more. Turbocharging is a key component, combined with sophisticated engine management, 'lean burn' technologies and the potential use of bio-fuel, such as Saab BioPower and E85 bioethanol.Back to Saab turbo pioneer Dr Per Gillbrand. He shared a similar philosophy when it came to efficient engine design. "All engines have an oil pump, a fuel pump and a water pump", he used to say. "So why not an air pump, which is all a turbo really is. I think it's odd that all engines don't have one!" Nowadays, thanks to the power of such independent thinking, an increasing number do. |
