This week at the Paris Motor Show Audi provides a glimpse of the future shape of design, along with automotive and drive concepts, through its Audi crosslane coupé concept car. This vehicle is a new fusion of technology, engineering and design, and provides pointers to the design language of future Audi Q models.
With a Multimaterial Space Frame, the vehicle concept breaks new ground in terms of weight, costs and energy usage over its lifecycle, and is an evolutionary stage of Audi ultra – the lightweight construction principle from Audi.
An innovative and efficient plug-in hybrid drive based on a purpose-designed 1.5-litre three-cylinder TFSI and two electric motors redefines the benchmark, with potential fuel economy returns equivalent to 1.1l/100km and CO2emissions of just 26g/km.
The three-cylinder engine is coupled to an electric motor (EM 1), which acts primarily as a starter and an alternator. It develops an output of 67kW and 210Nm of torque. Electrical traction is provided by the second electric motor (EM 2) developing 114kW and 250Nm. The transmission makes it possible to connect the combustion engine complete with alternator to the remainder of the drivetrain by means of a claw clutch.
The dual-mode hybrid concept enables different operating modes. From 0 up to 55kph, drive power is supplied solely by the EM 2, which draws the energy it needs primarily from the battery. In serial mode, the combustion engine and the alternator (EM 1) produce electrical energy to support, relieve or substitute the battery should it be discharged.
The electric mode is possible up to 130kph. From around 55kph the drive system allows the TFSI engine together with the alternator to couple to the drivetrain – in this hybrid mode, the drive sources combine to optimise both efficiency and performance. Above 130kph, the three-cylinder engine becomes the main drive source but the EM 1 can support it if required
