A test mule of the Audi A4 B9 has been seen while undergoing testing in Germany around the Nürburgring ahead of next year’s confirmed market release. Taking into consideration this was only a test mule, there’s nothing to report in terms of design as the vehicle was wearing the body of the outgoing model. Nevertheless, we are not expecting a whole new design as the styling will likely end up being evolutionary rather than revolutionary.
At the moment of writing there aren’t many details available about the Audi A4 B9 but it is believed it will spawn a rugged-looking Allroad derivative and will also gain a plug-in hybrid version. The latter is expected to make use of a four-cylinder, 2.0-liter TFSI turbocharged gasoline engine with 211 bhp (157 kW) which will be combined with an electric motor packing an extra 95 bhp (71 kW). The battery pack will provide enough juice for up to 31 miles (50 km) on electric power and it is believed the model will not be available right away.
Audi’s engineers will likely tweak the 1.4 TSI engine and implement cylinder deactivation technology which will shut down two cylinders at low and medium loads, a process that will take a mere 36 milliseconds. This technology will allegedly reduce fuel consumption by a significant 0.5 liters / 100 km.
