RÉMI TAFFIN, DIRECTOR OF OPERATIONS
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.

POWER UNIT DETAILS
ICE
Suzuka is one of the toughest circuits of the year for the ICE. The sustained bursts of throttle test the internals’ strength, while the heavy braking events challenge reactivity and reliability.

Over 60% of the lap is taken at full throttle, but the majority of this comes in the second half of the track from the exit of the Spoon corner (Turn 14) to the chicane on the entry of the pit straight. This includes a pass through the 130R, which is taken at over 300kph despite being a flowing left hand bend!

The distance from Turn 14 to the chicane is 1,250m, equivalent to over 20% of the track. The driver will cover this distance in around 17secs, or 75m each second, roughly equivalent to the record speed reached by the Japanese bullet train, the Shinkansen.

With a top speed peaking at almost 340kph, Suzuka gives rise to one of the highest speed seen in the second part of the year. Inside the ICE the pistons will turn at an incredible 200 times per second, generating enormous internal forces.

TURBOCHARGER
Suzuka features several changes of altitude. The most obvious uphill section is through the Esses/Dunlop where the circuit rises by 25m. This impacts the turbo most of all, as it will rotate at a higher speed at the crest of the hill than at the bottom to produce the same amount of power. Engineers will factor this in when looking at turbo speeds throughout the lap.
MGU-K
Good performance at Suzuka is as much about traction in the slow corners as it is about top speed. The two slowest corners, Turn 11 (the hairpin) and the chicane, require accurate torque delivery to avoid wheelspin when the grip is low. They also provide opportunity for the MGU-K to recover energy under braking.

The second slowest corner is the chicane, which is taken at approximately 80kph. This is the best chance to recover energy as the cars approach at well over 330kph. Braking down to under 100kph generates huge amounts of heat and energy in the brakes. At this point there is even excess energy that engineers are not allowed to recover as a result of the regulations.
MGU-H
The flowing section of the Esses gives the MGU-H plenty of time to recover energy through the constant exhaust stream. Similar to Silverstone’s Maggotts and Becketts, the driver enters the complex at approximately 240kph and carries the speed through until the exit of the complex. He will spend approximately 15secs in fifth or sixth gear through this section.

Other than the two main straights, the Spoon Curve is another chance for the MGU-H. The driver enters Turn 13 at around 290kph and shifts down, but then quickly blips the throttle while turning in for Turn 14. The radial turn sees the driver at partial throttle for just over 5secs.

Pretty sure it was a one of that one. Normal service will resume.

Nice if didn't but we can hope Ferrari keep them honest

The Japanese Grand Prix yielded a double points finish for the Renault-powered Scuderia Toro Rosso team. Max Verstappen finished in ninth, with team-mate Carlos Sainz tenth.
Infiniti Red Bull Racing endured a difficult race. Daniil Kvyat started from the pitlane but made the most of his early pit stops to finish in 13th. Daniel Ricciardo suffered a puncture at the race start and finished in 15th.
Key race points:
• Carlos Sainz raced in the top ten for the first half of the race but lost positions when he clipped his front wing and required a wing change. He fought back to ninth, but was overtaken by Verstappen on lap 45 to finish in tenth.
• Max Verstappen started from 17th and made a good start to fight with the Saubers and McLaren by his first stop. A move on Alonso put him in the top 10, which he was able to maintain until the end of the race. He took Sainz for position later on.
• Daniil Kvyat finished in 13th despite starting from the pitlane following his qualifying accident. He was able to use a creative pit strategy to gain position.
• Ricciardo and Felipe Massa made contact at the start of the race, with both suffering punctures. Ricciardo’s stop cost him one lap, which he was not able to regain. He caught the two Manor cars and then Button to finish in 15th.
Rémi Taffin, Director of Operations:
A reasonable race with some points for Toro Rosso. Both drivers drove well and had clean battles with several other cars and then ultimately each other. Red Bull unfortunately had a painful race, but we had no reliability issues so were at least able to save engines for the future. Let’s hope Russia brings more fortune.
Cyril Abiteboul, Managing Director:
An unspectacular result for us today. The starting positions were always going to make things hard, but we made the most of the opportunities. The power units have behaved well on the whole and if we can start higher up the order at the next race in Russia we should have a much better reflection of the true performance of the power unit at this point in the season.
