2015 Borgward BX7 TS Concept Ultramodern and Innovative AWD Suv Review
The new conventionally powered Borgward SUV boasts the most advanced all-wheel drive system available today. Together with specialists from the renowned supplier company BorgWarner, which has already designed all-wheel drive systems for industry competitors such as BMW and Audi, engineers from Borgward adapted the BorgWarner GenV fully variable all-wheel drive system with an electronically controlled multiple plate clutch. “Our ultramodern and innovative AWD drive train offers a high level of traction reserve, which means outstanding agility and the highest degree of safety are guaranteed on all surfaces”, is how Bernd Kircher, Chief Engineer of the development team in Stuttgart, describes the benefits of the fully automated “torque-on-demand” drive system. In line with the driving situation and road surface conditions, the Borgward all-wheel drive system optimally distributes torque to the front and rear axles in order to ensure the best possible traction in the given situation.
Permanent all-wheel drive with variable propulsion
The Borgward operates with 90% propulsion to the front-wheels in normal situations. Only after the vehicle’s dynamic handling systems detect an unstable situation will torque be transferred to the rear axle in order to maintain stability. In other words, the all-wheel drive system reacts preventively within milliseconds. That’s because unlike conventional systems, the innovative Borgward 4×4 drive system uses an electronically controlled all-wheel multiple plate clutch with an electric actuator on the rear axle. This actuator continually receives sensor signals from the dynamic handling systems and uses the data to regulate the transfer of torque to the rear axle. The most ingenious thing about this system is that the actuator can pre-engage the multiple plate clutch and transfer torque to the rear axle before wheelspin occurs. Other systems that do not have an electric actuator always require drive slip in order to control the all-wheel clutch, which makes them less agile and efficient.
Fuel economy concept ensures the best possible energy efficiency
The drive system’s fuel economy concept is a completely new development. Here, low system weight and a new multiple-disc limited-slip differential on the rear axle lend the system a high degree of energy efficiency. It was previously not possible to completely disengage the rear axle in a torque-on-demand drive system due to its design principle. Approximately five percent of total torque always ended up at the rear axle, even if the given driving situation did not require this. The energy and dynamic potential of this torque was thus lost.
The sophisticated suspension, with MacPherson struts on the front axle and a multi-link suspension on the rear axle, combines extraordinary stability with balanced ride comfort and a high degree of active safety. The highly stable and sensitively regulated braking system with ventilated brake discs and fixed brake callipers is electronically controlled, which also makes it a key safety feature. The safety package here includes ABS, an electronic braking force distribution system, a braking assistant and an electric parking brake with an “auto hold” function.
Powerful: direct injection four-cylinder turbo-engine with 2.0 litres displacement
An impressive alternative to the Borgward BX7 PHEV cutting-edge plug-in hybrid is offered by the exceptionally sporty Borgward BX7 AWD T-GDI prototype with variable all-wheel drive and a direct injection four-cylinder engine. The ultramodern 2.0-litre direct-injection engine has an output of 165 kW (224 hp) and delivers maximum torque of 300 Nm starting at 1,750 rpm. This performance, that is perfectly aligned with it, ensures a superior driving experience. The Borgward BX7 AWD T-GDI sprints to 100 km/h in less than ten seconds and has a top speed of more than 200 km/h.
