Saab 9-4X 94 X Concept Car SUV

The Saab 9-4X BioPower Concept confirms Saab’s plans for the crossover segment.

The design of the Saab 9-4X BioPower Concept reflects a Scandinavian principle of simplicity of form, with clean and uncluttered lines, free of any moldings or roof bars. Frontal styling and interior design draws inspiration from Saab’s Aero X concept. Innovative load-carrying solutions include a unique ski equipment stowage system, developed with mountain sports specialists Salomon.Optimized for bioethanol (E85) fuel,  the four-cylinder, 2.0-liter BioPower turbo engine demonstrates Saab’s commitment to downsizing. Delivering 300 horsepower and strong torque of 295 lb.-ft (400 Nm), together with substantially reduced CO 2 emissions. The compact, all-aluminum, four-cylinder BioPower engine combines the benefits of turbocharging, direct injection and variable valve timing for the first time with E85 fuel. Its green formula equates to 300 hp and 295 lb.-ft. (400 Nm) of torque without the weight, size, fuel consumption and higher emissions of a larger, naturally aspirated engine offering similar performance.Mated to the industry-leading Saab XWD (“cross-wheel-drive”) system, this advanced powertrain promises to make driving to a destination as enjoyable as the adventure itself.The Aero X-inspired driver-focused cockpit of the four-seater cabin features a flush-mounted starter button and infotainment controls, that sweeps up from the central console to the main display screen. Signature green lighting is used for all instrument illumination, while other subtle references to Saab’s aviation heritage include the “altimeter” speed read-out scale and aircraft-shaped trim on the steering wheel. The panoramic glass roof is in harmony with a car designed to deliver the enjoyment of outdoor pursuits.SThe rear cargo deck features a sliding floor with a fold-out aluminum ski holder, through which up to three pairs of skis and poles can be slotted. Boots are stowed in an underfloor, heated compartment and, for maximum practicality, the entire rear cargo area is covered in a waterproof and scratch-resistant rubber skin.Saab’s all-wheel-drive system splits torque delivery between both the axles and the rear wheels, via an electronically controlled rear limited-slip differential. XWD rewards the driver by giving an enhanced, “positive force” chassis balance.Saab 9-4X Concept: Technical SpecificationsBioPower engine1998 cc; four cylinders; 86.0 / 86.0 mm bore / stroke; aluminum cylinder head and block; DOHC, chain-driven. four valves per cylinder; twin counter-rotating balancer shafts; forged steel crankshaft; steel connecting rods; aluminum pistons; oil spray cooled; direct injection; VVT; inlet and exhaust sodium-filled exhaust valves; Saab engine management system; twin-scroll turbocharger; intercooledBioPower engine data * Max. boost pressure at maximum torque: 1.2 bar * Compression ratio: 10.5: 1 * Max power (E85): 300 hp (221kW) @ 5400 rpm. * Max. torque (E85): 400Nm (295 lb.-ft) @ 2600-5100 rpm * Max power (gasoline): 245 hp (180 kW) @ 5300 rpm * Max. torque (gasoline): 353 Nm (261 lb.-ft.) @ 2500- 5250 rpm * Fuel consumption (combined): 10.5L /100km (22.4 mpg) on gasolineTransmission * Saab XWD (“cross wheel drive”) all-wheel-drive system, electronic rear limited-slip differential (eLSD) * Six-speed automatic transmission, steering wheel controlsSuspension * Front: MacPherson struts, aluminum control arm and knuckle, anti-roll bar * Rear: Multi-link, aluminum H-arm and knuckle, anti-roll barSteering * Rack and pinion, hydraulic power assistanceWheels, tires * 21inch, 245/55R21Brakes * Hydraulic, dual circuit, vacuum booster * Discs front / rear: 378 mm / 378 mm (all ventilated)Performance data (preliminary)* 0 – 60 mph: 7.9 sec * Top speed: 146 mph
