Project: Van+Large Trailer cd 0.36 to 0.23, CFD test Asias explains: "We are trying to substitute large 7 meter van (with 1200 kg payload) by a medium van + aerodynamic trailer. Before we were getting aprox 22 mpg at 65 mph, but we want go somewhere near 33 mpg." Using a CFD model (computational fluid dynamics), he documents a test beginning at 0.36 cd (only the van) resulting in a 0.233 cd with the trailer attached and gap filled. By ausias - 4 replies

Got 2.25 L/100 km 104.36 mpg (US) at 80 km/h avg speed Vekke's modified Volkswagen Lupo 3L is getting closer to his 2L / 100 km goal (118 mpg US) at 100 km/h (62 mph) average speed. The car currently has a number of major aerodynamic modifications - one of which is just 80 mm of ground clearance - and more are planned. By Vekke - 18 replies
