Saab 9 3 ePower Concept 2010





- Saab 9-3 ePower Concept, 2010
The Saab Automobile is taking its first step towards developing an all-electric vehicle with the Saab 9-3 ePower. Making its public debut at the 2010 Paris Motor Show, the Saab 9-3 ePower is the prototype for a test fleet of 70 vehicles which will participate in extensive field trials in Sweden in early 2010.
The performance of the cars will be evaluated under a variety of real world driving conditions as part of the development process for a purpose-built, electric Saab vehicle. Targets to be verified include a projected driving range of approximately 200 kilometers through the use of high density energy storage in lithium-ion battery cells.
The Saab ePower is the first electric vehicle from Saab and is a result of a co-operation between Saab Automobile, Boston Power (batteries), Electroengine in Sweden AB (electric power trains), Innovatum (project management) and Power Circle (Swedens electric power industry trade organization).
Mid-sized sports combi with zero emissions
The Saab 9-3 ePower is the first all-electric car to offer its occupants the comfort and size of a wagon bodystyle. Saab engineers have integrated an electrical architecture within the shape and dimensions of a conventional Saab 9-3 SportCombi.
Under the hood is a 135 kW/184 hp electric motor driving the front wheels through a single-speed transmission. Instant torque enables zero to 100 km/h acceleration is just 8.5 seconds, together with a top speed of 150 km/h.
The compact yet powerful 35.5 kWh lithium-ion battery pack is accommodated in a modified floor-pan, mainly in space within the cars wheelbase previously occupied by the exhaust system and fuel tank. This enables an optimum weight distribution and excellent driving dynamics similar to those of a standard SportCombi.
Inside the cabin, a conventional, automatic-style gearshift lever provides selection of drive, neutral, park and reverse. The rev-counter, fuel and turbo boost displays in the main instrument cluster are replaced by read-outs for battery status, power consumption and driving range, all illuminated in green. To optimize space, an electric park brake is fitted.
Electro-hydraulic power steering is used and the cabin is equipped with full air conditioning, via a compressor powered by the battery pack. A separate 12-volt battery, for the lights and cabin ancillaries, is also charged from the battery pack via a current transformer
The operation of the vehicles powertrain is controlled by a version of Saabs own in-house Trionic 8 engine management system, with new software written for an electric vehicle application.
Long driving range with excellent durability
The Saab 9-3 ePowers projected driving range of approximately 200 kilometers pushes out the boundaries for current EV performance. Key to its long range are battery cells which have an energy storage density substantially greater than the best currently used in EV applications. High energy density also contributes to a lower battery weight.
The battery pack has a capacity of 35.5 kW/h and is designed to operate with full power in ambient temperatures as low as -30ºC, at least 10ºC below the operating level of other battery packs on the market today. Another key benefit is the use of air, instead of liquid, cooling which contributes to lower cost and further weight-saving in the packs design.
The pack is intended to support re-charge cycles equivalent to about ten years average use. It can be fully recharged from a domestic mains supply in about three to six hours, depending on depletion status. Charging times can be greatly reduced if the voltage of the electrical feed is raised, as there is no limitation on the batterys input capacity.
Test driving experience is expected to validate the performance of this advanced battery pack, which is designed to operate reliably within a full depletion buffer set at only 12 percent of total capacity, a much lower operating margin than used in the management of other packs.
Its lithium-ion battery cells are also the first to receive a Nordic Ecolabel accreditation for their environmental safety and sustainability, which includes manufacturing processes.
The Saab 9-3 ePower meets the high crash worthiness standards that Saab applies to all its vehicles. The cars power pack is located outside the occupant compartment in non-deformable structural zones, well protected and encapsulated. The battery management and monitoring system supports safe performance during normal driving and in crash conditions.
Extensive user trials
Hundreds of drivers and their families be enlisted by Saab and its development partners during a extensive test driving and evaluation program involving a 70-strong fleet of Saab 9-3 ePowers in central, west and eastern Sweden during 2011-12.
The Saab ePower project team in Trollhättan monitor the performance of the cars across a wide variety of usage patterns and driving conditions. To log essential component data, all vehicles will be equipped with aircraft-style, black box recorders.

Saab PhoeniX Concept 2011









Saab PhoeniX Concept, 2011
Sleek, innovative and exceptionally efficient: the Saab PhoeniX Concept car showcases design features and technologies which will shape the next generation of cars from Saab.
Based on an new architecture which will empower the next Saab 9-3 model, the Saab PhoeniX Concept introduces aeromotional design: a visual evocation of the aerodynamic design principles and passion for innovation that inspired the creators of Saabs first car, the iconic Ursaab.
The Saab PhoeniX Concept embraces teardrop, liquid metal forms and a dramatic jet canopy-inspired glasshouse that gives fresh expression to Saabs signature wraparound and translucent ice-block design themes.
The clean, muscular shape enables an exceptionally low drag co-efficient of just 0.25 and also explores the potential for airflow management through the use of distinctive, side-mounted winglets.
Butterfly opening doors give easy access to a 2+2 cabin that blends simplicity with technology. It has a minimalist, stripped out feel, including a new expression of Saabs driver-focused layout and a world debut for Saabs innovative IQon infotainment and communications system. In true Saab tradition, there is also a surprisingly versatile cargo deck.
Under its rippling bodywork, the Saab PhoeniX deploys an innovative driveline, with an electrically-driven rear axle mated to a sophisticated 200 hp, 1.6-liter gasoline turbo engine. The result is an intelligent, hybrid all-wheel-drive capability that enhances driving pleasure while reducing fuel consumption. Combined cycle fuel economy and CO2 emissions are projected to be just 5.0 l/100 km and 119 g/km.
Aeromotional design
The Saab PhoeniX Concepts aeromotional design theme is inspired by Saabs aviation roots and draws expression from Ursaab, the prototype designed by aircraft engineers that spawned Saabs first generation of cars.
The entire form of the Saab PhoeniX Concept is seemingly molded by the wind. Tightly-wrapped by a liquid-like skin, the teardrop cabin resembles a dark ice block and appears to erupt from the center of the muscular bodywork. Two prominent ripples flow along the hood into the disguised windshield pillars, as if barely able to contain a powerful structure underneath.
At the rear, the dark screen also bursts through the outer skin of the rear deck, The tapering form hints at the teardrop rear styling of Ursaab, while the sawn off, kamm tail echoes a form from Saabs first coupé, the Sonett.
The low, frontal styling features a stretched interpretation of Saabs signature three-port grille. A body-colored central wing is now dominant and, in keeping with the cars minimalist design, LED headlamps are almost invisibly located at its tips. The new grille and hood forms are among the styling themes likely to be seen in future Saab production cars.
Butterfly-opening doors provide enhanced access to the low-slung cabin. There are no visible door handles or mirrors to disrupt airflow, and small cameras on slim stalks provide rearward vision.
Roof-mounted winglets enable Saab PhoeniX Concept to cleave the air as efficiently as possible. They channel airflow from the side of the car and direct it across the rear deck, reducing lift forces for greater stability without increasing drag.
Minimalist interior
In true Scandinavian tradition, the 2+2 cabin adopts a clean, minimalist look. It has the stripped out feel of a competition car, with shell-like seats and metalized interior sections that mimic the exposed network of a rollover cage.
Fresh expression is given to Saabs traditional, driver-focused instrument layout. A circular pod in front of the driver, shaped like the afterburner of a jet engine, presents data in tandem with the head-up display.
Angled at 45º to the driver, a separate module accommodates Saabs advanced IQon infotainment and communications system. For good ergonomics, the 8-inch touch-screen is as close to the drivers finger tips as the steering wheel.
Saab IQon (see separate release for full details) is a ground-breaking car communications platform using Googles AndroidTM operating system. Based on pioneering open innovation with third-party service providers and applications developers, it comprises an embedded computer platform which seamlessly connects to the internet when the cars ignition is switched on. The touch-screen provides access to audio and entertainment streaming, online navigation, on-board music storage and smartphone-like downloading of applications.
Red illumination for all instrument and ambient cabin lighting brings warmth and emotion to the cabin. This includes the floor, where LED light tubes are exposed by perforations in the black carpeting. It is all part of the new aeromotional design strategy, incorporating fire and ice effects.
The Saab PhoeniX Concepts curvaceous rear deck disguises a deep-opening tailgate. It gives access to a flat cargo deck, including fold-flat rear seatbacks and a cargo track for adaptable load carrying.
Efficient propulsion
Under its sculpted hood and beneath its cargo deck, the Saab PhoeniX Concept advances Saabs rightsizing powertrain strategy. Its propulsion system combines a highly efficient, 1.6-liter turbo engine with innovative, electric rear wheel drive technology.
The compact, all-aluminum gasoline engine packs 200 hp (147 kW) and includes variable valve timing and lift control, as well as start/stop functionality, minimal parasitic losses and a fuel cut-off function. A stainless steel tank is fitted, which is lighter and less expensive than a conventional plastic design,
The engine is supported by Saabs innovative eXWD system. It comprises a rear drive unit housing a 25 kW (34 hp) electric motor/generator powered by a small battery pack. Regenerative braking is used to sustain the batterys charge.
Now under development for the next generation of Saab cars, this hybrid propulsion system enables the benefits of all-wheel-drive while also reducing fuel consumption. Using a six-speed manual transmission, projected combined cycle fuel economy and CO2 emissions are just 5.0 l/100 km and 119 g/km.
The driver can select one of three eXWD operating modes. The default Eco mode delivers optimal fuel and CO2 efficiency with power assistance to reduce load on the gasoline engine at low speeds; Sport mode includes maximum power assistance with torque vectoring across the rear axle for greater chassis control; and Traction mode enables optimal grip at take-off and in slippery conditions.
Inside and out, the Saab PhoeniX Concept showcases new design directions and technologies that will be part of forthcoming Saab products.
