Renault Arkana, Captur hybrids impress in eco challenge - but why are they not for sale?
Formula 1 is no doubt one of the most expensive sports in the world and if you’ve seen any of the “Drive to Survive” shows you’ll know exactly why, despite the FIA capping the amount of money in an attempt to level the playing field.
There are, however, advantages for us lesser mortals whose driving is restricted to public roads in ordinary cars.
A lot of the technology developed around F1 eventually finds its way into our cars and that can only be a good thing as technology develops almost faster than we can keep up.
Taking a leaf from their involvement in F1, Renault has developed the E-TECH powertrains - hybrid and rechargeable hybrid - directly from their 2014 race car.
The same architecture has been transferred to E-TECH that combines an internal combustion engine with two electric motors: one for traction and the other as an alternator-starter, for a 100 percent electric start-up.
A “dog clutch” gearbox has also replaced mechanical synchronisers.
According to Renault the system has 150 patents, making the technology unique to the market.
We got to experience the technology for ourselves in a unique consumption challenge for eight hours around the Zwartkops racetrack that according to Renault “results in around 40 percent less consumption on an urban cycle for Hybrid E-TECH models.”
The cars in question were the Arkana Hybrid SUV Coupe and the Captur Hybrid.
