Saab 9-X BioHybrid: Boosting Efficiency in Compact Design and Performance

The Saab 9-X BioHybrid concept is a vivid vision of what a future compact car from Saab could look like. It is designed to reflect the priorities of youthful customers who seek progressive looks, responsible performance and high-tech communications, all in a sporty, fun-to-drive package.

Exploring design themes from Saab’s award-winning Aero X and earlier 9X concepts, the 9-X BioHybrid also demonstrates the potential for ultra-efficient power from a 200 hp (147 kW), 1.4-liter BioPower turbo engine backed by GM’s next-generation Hybrid system. Projected combined cycle CO2 emissions of just 105 g/km on E85 fuel are testimony to the promise of this package (see separate release for details).

The interior showcases an entirely new expression of Saab’s driver-focused cockpit design, together with innovative, seamless connectivity for personal nomadic devices and a rear cargo deck with a ‘low friction’ loading system.

“This car is all about efficiency in design and performance,” says Anthony Lo, Director of Advanced Design at General Motors Europe, who led the 9-X BioHybrid design team in co-operation with the Saab Brand Center in Sweden.

With its ‘turbine’ wheels placed at all four corners, minimal bodywork overhangs and an extended roof line, the proportions of the three-door Saab 9-X BioHybrid bring a dynamic, new dimension to conventional compact ‘hatchback’ looks.

The smooth ‘fuselage’ bodywork, now without any visible handles or door mirrors, the bold ‘wraparound’ window graphic and deep front grille are all themes inspired by the Aero X coupé concept shown at Geneva two years ago.

The car’s distinctive ‘shooting brake’ silhouette and rear functionality are developed from the 9X multi-role concept shown at Frankfurt in 2001. “You could say we designed this car from back to front, “says Lo. “The shape of the 9X is right for a car of this size, and the longer roof line helps the aerodynamics as well as providing more rear headroom and interior space.”

Echoing Saab’s roots in aircraft design, the 9-X BioHybrid also explores the potential for using active aerodynamics to reduce drag – and fuel consumption – at cruising speeds. Above 70 kph (43 mph), the upper and lower bodywork is reshaped as the roof spoiler automatically extends to further lengthen the roof line and an underbody diffuser is deployed from the bottom of the rear bumper.

The four-seater cabin introduces an entirely new execution of Saab’s driver-focused cockpit design. The central, floor-mounted console, with its angled controls and displays, is now eliminated. Instead, the driver- focused layout incorporates a main instrument panel that sweeps out from the top of the door moulding, arching across the driver. The embedded 3-D graphics appear to be ‘frozen’ in ice, continuing a Scandinavian design theme first seen in the Aero X.

Reflecting the needs of youthful customers, who expect easy access to multi-media both inside and outside the car, Saab has co-operated with Sony Ericsson in providing seamless in-car connectivity for a range of nomadic devices. The result is a wireless interface for streaming data, entertainment and satellite navigation functions for display and use. The interface also allows the simultaneous use of multiple devices when passengers are in the car.

At the rear, the cargo deck features an electrically-powered slide-out floor, which is activated when the bottom half of the split tailgate drops down The floor, and the back of the folding rear seats, is covered by ‘high friction’ rubber carpeting, which ‘grips’ items and holds them securely in place. For easy loading and unloading, aluminum bars automatically rise up and down as the tailgate is opened and closed.

The treatment of light is an important part of Scandinavian design and this is evident in the use of variable, white ambient lighting inside the cabin. The level of suffused illumination can be changed in intensity from bright, cold to warm and soft. It’s a personalized feature that could even be programmed, for example, to reflect the pattern of the changing seasons

“This car shows how our concept work can be carried forward into a compact format,” adds Anthony Lo. “It has a number of features which we will be developing further, such as the new driver-focused design theme, the importance of clean, uncluttered surfaces and the easy, seamless connectivity inside the car.”

Saab 9-X BioHybrid: Challenging Compact Convention

• Expressive design concept for compact car segment
• Energy efficiency: Saab BioPower, hybrid system, solar roof cell
• Clean ‘fuselage’ body with active aerodynamics
• New driver’s cockpit design
• Innovative seamless connectivity for nomadic devices

The Saab 9-X BioHybrid concept demonstrates how Saab design values could be expressed in a future compact car format. It is focused on youthful customers, typical of the premium compact car segment. They seek and value progressive product design and efficient performance, with easy access to high-tech communications, as well as a sporty driving experience.

The bold execution of the 9-X BioHybrid evolves visual design themes from the award-winning Aero X coupe (shown Geneva 2006) and multi-dimensional 9X (shown Frankfurt 2001) concepts. Inside, it showcases an entirely new expression of Saab’s driver-focused cockpit design, as well as innovative seamless in-car connectivity for all personal nomadic devices. Smart rear functionality features a cargo deck with an automatic sliding floor and a ‘friction’ loading system.

The small yet powerful 200 hp (147 kW), 1.4-liter BioPower turbo engine, optimized for bioethanol (E85) fuel, is backed by GM’s next-generation hybrid system (see separate release for details) for efficient, environmentally-responsible performance.

“This concept redefines conventional compact car design.” says Jan Åke Jonsson, Saab’s Managing Director. “It shows how progressive Saab design can be combined with smart features and responsible, rightsizing performance that is in tune with the expectations of younger buyers in this segment.”

Clean Scandinavian Design
With minimal bodywork overhangs, a wide stance and extended roof line, the three-door Saab 9-X BioHybrid brings a dynamic, new dimension to conventional ‘hatchback’ looks. The single window graphic, smooth ‘fuselage’ bodywork – without any visible handles or even door mirrors – and ‘ice block’ lighting themes draw on roots in Scandinavian design and Saab’s aircraft heritage.

At the front, the deep grille, that concave styling line in the hood pressing and the ‘wraparound’ windshield are inspired by the award-winning Aero X concept shown at Geneva two years ago. The car’s overall proportions and rear functionality are developed from the 9X multi-role concept shown at Frankfurt in 2001.

The 9-X BioHybrid cuts a unique silhouette in compact car design. The longer roof line and ‘sawn off’ rear styling contributes to a better aerodynamic performance and provides more interior room than a conventional compact hatchback with a sloping screen and rear trunk lid deck.

Touch-sensitive, keyless entry, eliminates the need for exterior door handles. And the use of small, retracting rear-view camera pods - instead of larger door mirrors - further contributes to the clean ‘fuselage’ effect, while also reducing aerodynamic drag at speed.

A large solar cell in the glass roof takes advantage of free energy from the sun by adding charge to the hybrid battery pack while the vehicle is parked and also when it is being driven.

At night, driving comfort is improved by automatic switching between high and dipped headlamps beams. A front -mounted camera monitors light sources on the road ahead and small shutters automatically ‘hood’ the high beam when on-coming traffic is approaching.

Active Aerodynamics
Echoing Saab’s roots in aircraft design, the 9-X BioHybrid explores the potential for using active aerodynamics to reduce drag – and fuel consumption – at cruising speeds. Above 70 kph (43 mph), the upper and lower bodywork is reshaped as the roof spoiler automatically extends to further lengthen the roof line and an underbody diffuser is deployed from the bottom of the rear bumper.
During heavy braking from over 100 kph (62 mph), the rear spoiler is raised, adding downforce over the rear axle. This action also reveals a reflector that increases the visibility of the brake light underneath, as a further warning of heavy braking.

Mould-breaking Interior
Innovative design is even more dramatic inside the four-seater cabin, upholstered in white leather at the front and black. Here, the 9-X BioHybrid introduces an entirely new execution of Saab’s driver-focused cockpit design. The central, floor-mounted console, with its angled controls and displays, is now eliminated. Instead, the driver- focused layout incorporates a main instrument panel that sweeps out from the top of the door moulding, arching across the driver. Only shared climate control and interior lighting functions remain in a small, central touch-sensitive panel.

The driver information zone is a flat, arc-shaped multi-layered acrylic surface, within which a row of five displays screens is embedded and illuminated in green 3-D graphics. This includes an ‘infotainment’ screen and control panel in the driver’s door moulding. Another ‘infotainment’ screen showing, for example, navigation with more in-depth information if selected, is located across the cabin for the front passenger. All displays and menus can be operated, adapted or minimized by the driver via controls on the fixed hub and rim of the steering wheel. The rear view camera screens are conveniently located above the main displays within the driver’s eye line.

White ambient lighting of the cabin is taken a step further by a selectable level of suffused illumination, varying in intensity from a bright, cold to warm and soft. This is a feature that could even be programmed, for example, to reflect the changing seasons

Seamless Communication
The potential for seamless wireless connectivity (Bluetooth or WiFi) with one or multiple nomadic devices (mobile phones, PDAs etc) is demonstrated by Saab’s co-operation with Sony Ericsson in developing an interface for streaming data, entertainment and satellite navigation functions for in-car display and use. The interface allows the simultaneous use of devices, such as a phone and MP3 player, when passengers are in the car.

The functions of the nomadic device are controlled by a screen in the car, for example, while it is kept in the user’s pocket. The smarter the device, the more functions in the car. Depending on the type of device, it can upload its own displays, as well as lock /unlock the car and even remotely change in-car pre-sets. It is all part of the concept’s vision in appealing to younger buyers who expect easy, on-the-move access to multi-media.

Smart Load-carrying
At the rear, the cargo deck features an electrically-powered slide-out floor, which is activated when the bottom half of the tailgate drops down over the rear bumper. The top section, hinged from the roof, can be opened separately so that smaller items may be dropped inside easily.

The entire floor area, and the back of the folding rear seats, is covered by ‘high friction’ rubber carpeting. When the tailgate opens, aluminum bars in the floor are automatically raised just above the level of the high friction surface, making it easy to slide items inside. When the tailgate is closed, the bars are lowered to allow the high friction surface to ‘grip’ items and hold them securely in place.

The ‘default’ setting for the rear seats is the folded down position, reflecting the fact that the youthful target buyers for such a car will use its load-carrying capability more often than they need to accommodate rear passengers.

Vision
The 9-X BioHybrid has been created by a team under Anthony Lo, Director of Advanced Design at General Motors Europe, working in co-operation with the Saab Brand Center in Sweden.

“This car is about efficiency in design and performance,” he says. “We have taken exterior themes from our previous concept work, such as the clean surfaces and lighting treatments, and tuned them for a compact format.

“Inside the car, the new driver-focused design theme and the easy, seamless connectivity are both features we will be developing in future.”

Rightsizing with Saab BioPower and Next-Generation GM Hybrid System

The Saab 9-X BioHybrid demonstrates the potential of partnering bioethanol fuel with the next-generation GM Hybrid system to deliver exceptional levels of efficiency and performance.

Optimized for E85 fuel, the small, 1.4-liter BioPower turbo engine generates a substantial 200 hp/147 kW on E85 and an even more impressive 280 Nm (207 lb.ft) of torque, as well as reduced CO2 emissions compared to gasoline. With a full flex-fuel capability, it is a rightsizing formula backed by hybrid technology, giving projected fuel consumption when running on gasoline over the combined cycle of just 4.9 l/100 km and 117 g CO2/km. When running on E85, CO2 emissions are projected to be even lower, at just 105 g/km, with estimated fuel consumption of 6.4 l/100 km.

Mated to a six-speed manual gearbox with an automatic clutch and steering wheel controls, it is a sophisticated powertrain tailored to meet the environmental and energy-saving priorities of modern day motoring.

BioPower Optimized
Saab already leads the automotive industry in applying its turbocharging expertise to enhance the performance and environmental benefits of E85 fuel (85% bioethano/15% gasoline). Saab BioPower models are the top-selling flex-fuel vehicles in Europe and produce more power with E85, as well as less CO2 emissions compared to gasoline.

The Saab 9-X BioHybrid now takes this proven BioPower flex-fuel technology further by using an engine that fully exploits the high octane benefits of E85 fuel. It uses a higher compression ratio (10.2: 1) and turbo boost pressure (up to 1.6 bar) than would be possible with a gasoline-only engine. This is because E85 has a higher octane rating (104 RON) than pump gasoline (95 RON), which makes it more resistant to harmful pre-detonation, or ‘knocking’, as the fuel/air mixture is compressed in the cylinder.

Whilst optimized for E85, the engine retains a flex-fuel capability and will still run on gasoline, although it will not produce as much power. The engine management system is able to adjust the ignition timing and boost pressure to ensure there is no pre-detonation due to the higher compression ratio.

Running on E85 fuel, this lightweight yet sophisticated BioPower engine delivers the power characteristics of a much larger powerplant. That impressive torque of 280 Nm (207 lb.ft), for example, is available all the way from just 1,750 to 5,000 rpm. It’s another demonstration of Saab’s rightsizing engine strategy – offering exceptional power without the greater weight, size, fuel consumption or emissions of a larger, naturally-aspirated engine.

The advanced specification of this engine also includes direct injection (DI), with centrally-located fuel injectors, and continuously variable valve timing (VVT) on both the inlet and exhaust sides.

DI delivers fuel directly into the combustion chamber of each cylinder, instead of the intake port. . VVT then manages airflow by opening and closing the intake and exhaust valves to improve combustion, and allow the use of a higher boost pressure. The result is greater low-end torque and improved fuel consumption. The central location of the fuel injector, at the top of the combustion chamber, allows further optimization of the intake ports for improved engine breathing.

Next-Generation GM Hybrid System
Fuel consumption and CO2 emissions are reduced still further by the addition of the next-generation GM Hybrid system, which features a lithium-ion battery and a significantly higher power capability to capture more energy and more electric boost than the current GM Hybrid system. An electric motor/generator, belt-driven from the engine’s crankshaft, replaces the conventional alternator. Electrical power is delivered and stored by the compact lithium ion battery pack, located under the rear cargo floor.

The electric motor reacts spontaneously and complements the torque of the boosted engine. With this combination of turbocharger technology and a hybrid propulsion system, the dynamic behaviour of the downsized powertrain is improved still further.

At take-off from rest and during overtaking manoeuvres, the electric motor adds accelerative power. It is also used to re-start the engine, supporting the automatic fuel-saving function whenever the car is stationary. To further improve efficiency, the hybrid system enables a longer fuel cut-off during deceleration and braking.

The electric motor also acts as a generator. It can be powered by the engine to charge the battery pack and support vehicle electrical loads. Or it can be used to capture the vehicle’s kinetic energy when decelerating, storing that energy in the battery pack. This second type of charging is commonly known as ‘regenerative braking’. Sophisticated electronics manage AC/DC and all voltage interfaces, including the 12-volt in-car supply.

The combination of GM Hybrid and Saab BioPower technologies has significant synergies. The hybrid system adds accelerative power and, in effect, improves throttle response. This allows further rightsizing of the engine with additional fuel consumption benefits. Engine rightsizing and hybridization complement each other, the combined benefit being greater than that of the individual technologies.

Responsible Performance
The 9-X BioHybrid also harnesses power from the sun. The large solar cell in the glass roof takes advantage of this free energy by adding charge to the hybrid battery pack while the vehicle is parked and also when it is being driven.

Apart from saving fuel and energy, responsible performance means ensuring high standards of safety. In addition to a full arsenal of electronic stability and braking systems, the front seats of the 9-X BioHybrid are fitted with 4-point seatbelts to help hold occupants firmly in place. The seat-mounted belts are extended electrically from the sides of the seatback over each shoulder and are connected together by a central buckle.

Active safety measures are taken a step further with the Lane Departure Warning (LDW) function. A front-mounted camera scans the road ahead and warning messages are flashed on the driver information display if the car veers across lane markings. The same camera is also used to monitor light sources at night. Small shutters automatically ‘hood’ the high headlamp beam when on-coming traffic is approaching.

Saab Concepts Inspire New Product Offensive

In showing two concept cars, the 9-X BioHybrid and 9-4X BioPower, Saab is preparing for an unprecedented level of product development, says Jan Åke Jonsson, Saab Automobile’s Managing Director.

The 9-X BioHybrid is a vision of what a future premium compact car from Saab could look like; while the 9-4X BioPower is a statement of Saab’s intent to enter the growing Crossover segment. Together, they are evidence of Saab’s plan to enter all major segment of the car market.

“The Saab brand is on the move,” says Jonsson. “The 9-X BioHybrid shows what we could bring to compact car design in a number of areas, such as progressive design, driver focus and efficient performance. It also shows that we are determined to grow the brand by expanding our product portfolio.

“The 9-X BioHybrid is a visionary design, looking ahead to where we could be. We are showing it alongside our Crossover concept, which is closer to going on sale. The global Crossover segment has trebled in the last seven years, but we have not been able to offer customers a Saab alternative. That will now change and the same will apply to other growing segments where we see potential for our brand.”

In the last five years alone, Saab has launched four new models and now shown six concept cars, including the award-winning Aero X coupé. It has also introduced industry-leading BioPower flex-fuel models and advanced all-wheel-drive technology (Saab XWD).

“While we have come a long way in the last five years, I can say the next five years will see the rate of product development accelerate,” adds Jonsson. “Our target is to have the Saab brand represented in all major segment of the market, and to do that we anticipate rolling out new products at a rate never seen before from Saab.”

Jonsson points out that each new Saab product, like the upcoming Crossover vehicle, will draw inspiration from the brand’s strong Scandinavian roots in the areas of progressive design, driver focus and responsible performance with concern for the environment.

The Saab Brand Center in Sweden is playing an important role. A cross-functional group of designers, engineers and marketers, they are custodians of the Saab ‘genes’, tasked with nurturing and developing all the qualities that go into making a Saab a Saab.

Their responsibilities range from developing future product proposals to ensuring consistent brand communication on a global basis. In on-going product development work, brand center teams liaise with GM colleagues around the world, leveraging the group’s huge technology and engineering resources for potential Saab applications.

The Saab Brand Center also works closely with GME’s European Design Center in Rüsselsheim, Germany. It is a unique organization within GM’s global structure, with a unique way of working.

“Our brand values have never been more relevant than they are today,” adds Jonsson. “Customers increasingly want premium vehicles that meet their particular lifestyle needs which are also sporty and environmentally responsible. It is our intention to offer them products from Saab as a fresh and distinctive alternative choice.”
