Fuses and relays Toyota Avensis (T270), 2008–2019

Table of Contents

Toyota officially unveiled the third generation of the Avensis at the 2008 Paris Motor Show. Designed by Toyota’s European design center in France, the vehicle was manufactured at the company’s plant in the UK. The model was offered in two body styles: sedan and estate (station wagon). The exterior styling shifted from smooth contours to sharper, dynamic lines—including large, swept-back headlights—achieving an aerodynamic drag coefficient (Cd) of 0.28 for the sedan. While retaining a 2,700 mm wheelbase, the new Avensis was 50 mm longer than its predecessor. The powertrain lineup featured three petrol and three diesel engines with improved emissions performance, with a continuously variable transmission (CVT) available as an alternative to a manual transmission.
