Filed under: Hybrid , Sedan , Toyota , New Car Reviews People, us included, make a big stink about the importance of family sedans. There’s no doubt they’re critical – they represent a huge slice of the market’s annual sales and profits. However, despite accounting for far fewer transactions than the midsize sedan segment, the fullsize sedan is getting attention from manufacturers now that our market’s entire lineup of those (slightly) smaller four-doors has turned over in the last two years or so. As most of the fullsize segment’s mainstays derive a fair bit of their platform and powertrain technologies from their midsize cousins, these larger four-doors offer the potential for fatter profit margins, too. And with the newly stylish duds found on many of the industry’s most successful midsize sedans, it’s only right that automakers no longer think about fullsizers as big, squishy, vanilla family haulers with flat seats, vague steering and a thin layer of ‘luxury’ in the form of faux wood trim. As manufacturers have again started diving into large sedans feet-first, the cars themselves have become sharper. The interiors are now of a higher quality and loaded with tech, while the exteriors have become further extensions of each manufacturer’s design language. There’s perhaps no greater example of this than the Chevrolet Impala and Ford Taurus , two models that evolved from subpar offerings into market leaders. This segment-wide transformation happened quite quickly, whether because of coincidental timing or because manufacturers are trying to get more out of their big cars, recognizing they account for a small portion of overall sales (just 3.5 percent of the new-car market in the first half of 2013). The 2013 Toyota Avalon Hybrid is one such vehicle.
