Racing Questions

Rémi Taffin has been involved with Renault since 1999, he is currently Renault’s Formula 1 engine technical director, with overall responsibility for the power unit development at the Viry-Châtillon site. Rémi main task is to ensure his engineers produce the perfect Engine that works with the chassis, which is an incredibly hard task, you can have a engine that produces loads of torque,but must be able to be drivable and be also balanced with the chassis.

Drivability is key as all the new power units have so much torque, with the added involvement of KERS its not just about raw power, delivering the power is a balancing act along with reliability.

Rémi is no stranger to winning in Formula 1, having  worked directly with two world champions, Jenson Button and Fernando Alonso.

With two operation facilities Enstone and Viry-Châtillon, Renault is in a strong position to use the key skill sets of both  UK and France technicians.
