Renault: Good clean fun
Good and evil, ying and yang. It all balances out in the end, or that's what Renault must be hoping for.
Just as the French firm announces its new clean, green eco² range of cars, it's also come up with a track day calendar for its hot hatch models.
So, Renault makes amends for its carbon-frenzied, tyre-squealing track fun with cars that have low emissions, excellent economy and are very recyclable.
You can currently pick from a Megane 1.5 dCi that runs on biodiesel or a 1.6-litre petrol-powered car that uses bioethanol, or the turbocharged Clio 1.4 TCE 100.
As for the Renaultsport track days, there are four UK events across the summer and a fifth day at Spa Francorchamps in Belgium.
You can turn up at any of these track days in your own car - even if it's not a Renault - and then you can sample the current range of Renault hot hatches.
Also on duty at the track days are a Clio V6 and Renaultsport Spider, which certainly gets our ying yanging.
