Toyota’s 1.2L turbo engine to power Auris facelift
Every carmaker wants to introduce smaller yet more efficient engines to power their forthcoming models. Auto manufacturers around the world are embracing the turbo-charged route to smaller and efficient engines, which are low on emissions. Gradually, the demand has been shifting from the naturally aspirated powertrains to the turbocharged and supercharged ones. While the automakers like Suzuki, Honda, Ford etc. has already joined the race in offering the turbo engines, Toyota is the latest carmaker to join the bandwagon. Toyota’s 1.2-litre capacity petrol engine, codenamed the 8NR-FTS is going to make its way under the hood of the Toyota Auris Facelift.
The all-new turbo engine comes with technologies generally seen on other carmaker’s products in the past. With a displacement figure of 1,196 cc and a compression ratio of 10.0, the in-line 4-cylinder turbocharged mill bangs out 116 PS of power @ 5,200-5,600 RPM and 185 Nm of torque @ 1,500-4,000 RPM. Thanks to the variable valve timing (VVT-iW), a superior technology which mainly helps the engine to use its Atkinson cycle forcing the turbo to work according to the load, to deliver the highest fuel efficiency. This also works by keeping the exhaust water cooled, whose role is to keep the temperature under control for acceleration and maximum torque output. The D-4T direct injection turbo technology is also the part of this whole system, which adds additional torque for better fuel efficiency delivery and emissions output.
Credit also goes to the vertical swirl (As Toyota calls it) which is present inside the cylinder head, which helps the turbo engine to be fuel-efficient, promising a healthy mileage of 19km/l. As per sources, the newly developed turbo engine will be first launched in Japan, thereafter in Europe followed by the US. The upcoming Toyota cars are expected to get power from this freshly developed turbo mill.
With the country’s emission norms getting stricter, we can expect the same engine to make its way to the Indian shores as well. If not, we can expect something similar from Toyota India especially for the Indian market. This will gradually shrink the use of naturally aspirated engines in upcoming cars with turbocharged ones. Some of the cars which are powered by turbo-charged engines in the Indian market are—
> Tata Zest and Tata Bolt powered by the 1.2-litre Revotron turbo petrol engine.
> VW Polo GT TSI features a 1.2 litre turbo petrol motor.
> Ford EcoSport comes powered by a 1.0-litre EcoBoost engine.
> Mahindra may soon launch its upcoming mini SUV with a turbocharged engine.
