Volkswagen Group’s utilisation of a ‘defeat device’ to produce inaccurate results for vehicle emissions tests in multiple consumer states, leads it to face potentially crippling fines, possible criminal liability, civil suits, and detriment to its own company caused by the loss of trust. However, this article considers a further issue, namely implications of the violations on taxation legislation and pursuant claims for losses as a result of lost tax revenue or recalculated taxes. With vehicles falling outside of the tax band they were purchased within, there is confusion around the world about how this will affect the tax status of the vehicles and those that own them. Vehicles could be re-banded or reassessed for a variety of different tax purposes, increasing the tax liability of the vehicle historically and prospectively to reflect the actual emissions or fuel consumption based on how the charge is designed. Through a comparative study, this article considers varying tax issues in several different countries across the globe for which the manufacturer may be liable for the life of the vehicle. This will seek to establish the scale of the potential liability for Volkswagen (vw) Group that has not yet been explored. Finally it examines how international cooperation could produce more satisfactory settlements for nations and customers.

The perfect wing is a dream that many airplanes has manufactured have been striving to achieve since the beginning of the airplane design. There are some aspect that most influence in aircraft design lift, drag, thrust, and weight. The combination of these aspects leads to a decrease in fuel consumption, which reduces pollution in our atmosphere and increase in economic revenue. One way to improve aircraft performance is to modify the tip of the wing geometry, which has become a common sight on today’s airplanes. With computational programs, the effects on drag due to wingtip devices can be previewed. This research was done numerically by using turbulence model k-ω SST. Reynolds number in this research was 2,34 x 10 4 with angle of attacks are 0o, 2o, 4o, 6o, 8o, 10o, 12o, 15o, 17o and 19o. The model specimen is wing airfoil Eppler 562 with winglets. Two types of wingtips are used: forward and rearward wingtip fence. From this study, it was found that wingtip fence reduced the strength of vorticity magnitude on the x axis compared to plain wings. The leakage of fluid flow effect at the leading edge corner of the wingtip, giving pressure gradient and slightly shifting towards the trailing edge. this occurs in the plain wing and rearward wingtip fence but does not occur in the forward wingtip fence..
