Aerodynamic simulation technology was developed in 2010 to enable air flow around tyres to be simulated under the conditions envisaged to be encountered in actual use (i.e., with tyres mounted in the wheel wells and revolving), and the scope of simulation is presently being expanded to include the entire vehicle.

Like design, there are several trends blowing through wind tunnels today. “We’re constantly trying to integrate progressive aero with customer satisfaction,” Tortosa said. One feature that’s gaining momentum is the active shutter.

Saab 92 : 1947 | Cartype


'V2 Sagitta' and is built by Kurt Volkhart 1947

After its rebirth it has been namely transported in the Wolfsburg wind tunnel and determined with 0.217 at 2.10 m³ cross-sectional area a drag coefficient that is unmatched by any vehicle currently built in mass production. Only the Mercedes CLA comes very close to it with 0.23 and the VW XL1 produced in small series surpasses it with 0.189 at 1.5 m³ cross-sectional area.

The car therefore represents a particular achievement for the time in which a Volkswagen Beetle had a drag coefficient of 0.46 to 1.8 m³ cross section. By the way the wheel guards contribute very much to the lower air resistance, while a rear spoiler, surprisingly, only very little effect. After all, the car delivers with the low engine power 140 km/h. However, appears somewhat exaggerated the then obviously from the manufacturer specified value of 0.16. 03/13

Jaguar - Obsessionistas - collectors & their collections

Malcolm Sayer was steeped in the principles of aerodynamics by the time he joined Jaguar in 1952. Sayer helped to shape Jaguar’s first Le Mans winner, the C-Type, and went on to design the iconic D-Type, XJ13 and E-type, with their beautiful and streamlined profiles. Sayer’s working methods involved plotting the co-ordinates of complex curves with slide rules and logarithmic tables and he also pioneered the use of wind tunnels to test a car’s aerodynamic properties. Sayer’s last car was the XJ-S though, sadly, he died in 1970, before it went into production.
