Toyota has unveiled the all-new Prius for the first time globally. Coming with the tagline "Just in time for the 21st century," the Prius was first launched in 1997 as the world's first mass-produced hybrid car. The popularity of the Prius led the expansion of Hybrid Electric Vehicles in the 25 years since it was first launched as a new-generation eco-car with outstanding fuel efficiency. Total cumulative sales of the Prius worldwide have reached about 5.05 million units, helping reduce CO2 emissions. The new drivetrain is an upgraded version of that used by the previous Toyota Prius Plug-in with a 147bhp 2.0-litre four-cylinder petrol engine and a 158bhp Electric motor for a combined 221bhp. Its electric range has been boosted by 50 per cent - with the new Prius able to travel around 58 miles with the engine off. Following Japan, the new Prius will be launched in North America, Europe, and other countries around the world.
