Toyota releases details on 4th generation Prius hybrid with 18% better mileage

Toyota's popular Prius Hybrid looks to be getting better mileage (up to 40 kilometres a litre) as well as improved engine, interior and driver features. Coming to Japan in December and expected to hit North America next year, the new Prius has imprvoed batteries which are 10 per cent smaller than the current version while better options for engine performance, and even all-wheel drive, are being considered.
"The Toyota Prius is the most successful hybrid on the planet, but its success hasn't expanded to other hybrids, and even the Prius has struggled to maintain sales in recent years," said Karl Brauer, senior analyst for Kelley Blue Book.
