New Avensis. Strength Of Character. Today. Tomorrow. Toyota. The Toyota Avensis is a large family car built by Japanese automaker Toyota since the 1998 model year. The Toyota Avensis was introduced in 1997, to create a more modern name when compared with the reliable, but dull Toyota Carina E/Toyota Corona. Like its predecessor the Avensis was reliable, and proved a sales success for Toyota Europe. Over the years, the Toyota Avensis has advanced in size, technology, power, and economy to challenge its established European rivals, the Vauxhall Vectra, Ford Mondeo and Peugeot 407.
