The car Artega should build - Artega GT 2.0 TFSI

We haven't heard much from Artega lately, at least they were at the Geneva Car Show a couple of weeks ago.
Given the current trends and sensitivities I wonder whether Artega shouldn't consider adding another model or even replacing the one they have. As you know the Artega GT has the Volkswagen V6 engine on board, basically the unit from the Passat R36 coupled with the DSG box. While this certainly guarantees acceptable performance the engine isn't known for fuel efficiency and low CO2 emissions. So why not replacing that unit with a tweeked 2.0 TFSI engine? Performance would still be more than okay, but weight could come down to 1'235 kg, CO2 emissions to 174 g (from 220 g), average ECE fuel consumption from 8.9 to 6.7 l/100 km. Even the price could be reduced and maybe some of the components (breaks, wheels, etc.) could be made lighter optimizing performance and fuel efficiency even more. Important though would be an investment on the sound engineering side though and please alter the seating position so that even tall men can sit comfortably!
