Rémi Taffin : "Suzuka is one of the toughest circuits of the year for the power units. It has just about every type of corner imaginable, from flowing radial turns to hairpins and chicanes, and fast swoops. The average speed is also very high and top speed peaks at over 340kph, so every part of the units is put under pressure.
The result in Singapore shows that the performance is there and having introduced new parts earlier in the season we are confident in the reliability, but also the flexibility we have in our engine plans. While we are expecting Mercedes to be back on form in Japan we are hopeful we will be close enough to use the improved performance to get some good results."
Renault 2015 fast facts
The strong braking, frequent acceleration and high speed sections of Suzuka take fuel consumption to the upper limit, but there are plenty of opportunities for the K and H to recover energy under braking and therefore recharge the battery, bringing the fuel consumption within the allowed limits. Similar to Silverstone, engineers may use the practice of ‘overloading’ where slightly more fuel than necessary is put into the ICE. Running the ICE at a higher average fuel flow produces more overall power, which in turn allows the MGU-K to recover more energy to recharge the battery in order to match the driver demand, which leads to a better lap time.
Renault has won 10 Japanese Grands Prix. The first came in 1992 at the hands of Riccardo Patrese, with Damon Hill winning in 1994. Michael Schumacher took victory in 1995, and Hill again in 1996. Fernando Alonso won in 2006 and 2008 while Red Bull Racing have stood on the top step four times.
Renault has also powered 10 pole positions at the track, including five consecutive poles for Red Bull Racing between 2009 and 2013.
Suzuka is known for being a championship decider and Sebastian Vettel became the youngest back-to-back champion, and youngest double champion in F1 history in 2011.
