The results of the second set of tests. Cleaner petrol for the Volkswagen T-Roc
Six cars tested by Green NCAP in the second test series of 2023: Nissan Ariya, Renault Austral, Volkswagen T-Roc, Volvo XC40, Ford Fiesta and the new Hyundai STARIA.
The all-electric Nissan Ariya wins the maximum score – five stars – and stands out for its high charging efficiency. Indeed, the large battery allows it to travel more than 500km (WLTP cycle), despite the fact that the range decreases significantly (300km) in cold weather conditions (-7°C) and on the motorway.
Green NCAP strongly encourages manufacturers to increase the efficiency of the charging process so that more energy is left available for overall use.
The Renault Austral E-Tech Full Hybrid 200 – which deserves three stars – can count on a 400 V hybrid system which increases energy efficiency, especially in tests below motorway speed. It also benefits from a full hybrid engine which significantly reduces consumption in urban and extra-urban conditions.
2.5 stars to the Volkswagen T-Roc: 1.5-litre direct injection turbocharged petrol engine. This vehicle manages harmful pollutants in a very efficient way, reaching a rating of 7.7 points out of 10: the best result of the Green NCAP Clean Air Index for a car with an internal combustion engine.
The 48 V mild-hybrid Volvo XC40 equipped with a 2-litre turbo petrol engine with direct injection achieves 2.5 stars due to the significant amounts of greenhouse gases it emits.
The same score also for the petrol Ford Fiesta (which will no longer be produced from next June). The ST-Line Vignale 1.0 l version with 7-speed automatic transmission and 48 V mild hybridization was tested.
Lastly, only 1 star for the Hyundai STARIA, a large and heavy 7-seater van powered by a 2.2-litre diesel engine, which provides poor results in the energy efficiency and greenhouse gas efficiency indexes.
“The gratifying results of the Volkswagen T-Roc demonstrate that pollutant emissions can be effectively minimized even in conventional cars,” said Aleksandar Damyanov, Technical Director of Green NCAP. Collectively, the achievements of the Nissan Ariya, Renault Austral and Volkswagen T-Roc constitute an example of all-round technological progress that works in the interests of both consumers and the environment.”
