McLaren has a number of smaller aero developments for Spa

One of Formula 1’s most revered racetracks, the Spa Francorchamps road course has been a mainstay of the world championship calendar since it began in 1950. Renowned for its thrilling, high-speed corners and the capricious local micro-climate which can throw up blazing sunshine and heavy showers in equal measure, the mighty seven-kilometre circuit is still considered one of modern Formula 1’s greatest challenges.

"The reality is that we have tremendous faith in our colleagues at Mercedes-Benz and feel comfortable with both our engine’s performance and reliability. The recent engine failures suffered by Ferrari in Hungary and Valencia clearly demonstrate that even a homologated engine can break, so we take nothing for granted. There’s always an element of risk whenever you come to two fast and demanding circuits but we have the additional security of knowing both our drivers can each still suffer an engine failure without receiving a 10-place grid penalty."

"We’ve got a number of smaller aero developments in the pipeline - there’s nothing on the car that will be visually very startling, but there’s plenty of detail-work. We’re also focusing on further mistake-proofing our systems: the championship is going to be a hard-fought slog until the end of the year and we need to leave no stone unturned in our quest for additional performance and improved reliability. From a human and physical perspective, these two races are also pivotal to our title challenge - it’s vital that every member of the team pulls together to make sure these races pass without undue incident and set us up nicely for the final flyaway races."

"Yes indeed, we wanted to win. Nevertheless, our result in Valencia is no reason for us to feel disappointed. We scored 13 points which continues the trend of the previous three races. Since Silverstone, we have scored 55 out of 72 possible points in those four races and reduced the gap to the top of the constructors’ ranking from 33 to eight points."

"The top-four in the Drivers’ World Championship are covered by 15 points which is an exciting basis for the season’s finale. Five different drivers from three teams won the 12 races so far. Apart from the speed necessary for winning, obviously the reliability of the technical package will play the most important role. We have to be top-class when it comes to scoring points and everybody in the team is working hard to achieve this."

"The track of Spa-Francorchamps is the longest on the Formula 1 calendar at over seven kilometres, and, after Monza, where we will race one week later, the one with the second highest average speed of all Grand Prix circuits: in qualifying last year, this was 238 km/h. At both of those circuits, the engines are put under the highest strain of the season. The longest full-throttle part starts at Eau Rouge and leads all the way up to Les Combes; it is 1,900 metres long and takes almost 24 seconds. In addition, there is another, 1,600-metre-long full-throttle section between corners 14 and 18 which lasts 21 seconds.

"Apart from long straights where the cars reach speeds of up to about 320 km/h, Spa has every element to make a circuit interesting and challenging, from long and demanding corners like Pouhon and Stavelot to the tight hairpin La Source which can be taken at a speed of 70km/h. Drivers and engineers have to consider these completely different sections when they work on the set-up. The weather often plays tricks here on the teams and when it rains then not necessarily everywhere around the track. If there were to be a poll among the drivers as to which is the most demanding track, Spa would certainly be the circuit with the most votes."
