THE change to Elantra should be an easy one for Hyundai given the new generation is markedly different in appearance. Gone are the soapy shapes to a sharper, sleeker look that works well with the wider proportions. While it has not taken long to be mistaken for the Euro-look Holden Vectra and BMW 3 Series, the car improves on more than just the aesthetic - a more aerodynamic body reduces drag 12 per cent and helps improve fuel efficiency by up to 5 per cent.
