It would be intresting to have a V12 or V10 TDI engine mod for the ETK 800 Series. This would fit nice as a smooth cruising engine because of its 1000 Nm of torque and the meh but enough 500 HP thanks to the twin turbo system. ///V12 TDI EXAMPLE\\\ ============================================================================= https://www.ultimatespecs.com/car-specs/Audi/9625/Audi-Q7-60-V12-TDI-Quattro-Tiptronic-DPF.html ============================================================================= As for the engine model i think you can just merge two 6 cylinder engine models from the normal etk 856. ///V10 TDI EXAMPLE\\\ ============================================================================= https://www.ultimatespecs.com/car-specs/Volkswagen/1336/Volkswagen-Touareg-1-50-V10-TDI.html ============================================================================= I think it would work fine with two 5 cylinder vivace engine merged together as an engine model. This is just a cool idea i have thinked of and i think it is possible but i dont have the modding knowledge to make it real.
