    [​IMG] A quick look at what’s changed and what to expect at the opening round of the 2016 FIA-WEC racing series.

    [​IMG]Wayne Gerdes – CleanMPG – April 11, 2016

    2016 Porsche 919 Hybrid is ready to defend its 2015 FIA WEC Manufacturer Championship title throughout the 2016 racing season. The season opener at Silverstone is where it will all begin.

    The Silverstone 6 Hours is now a classic on the World Endurance Championship (WEC) sports car calendar. Since 2012, the race has been part of the FIA WEC. With its mix of high-speed corners, Silverstone represents a unique challenge for drivers and engineers while the British weather is traditionally unpredictable, as witnessed in 2014 when a heavy downpour ended the race early.

    For 2016, new regulations for the LMP1 category require manufacturers to use hybrid drivetrain and establish a direct link between performance and energy efficiency. This means that a large amount of energy from recovery systems may be used, but entails a proportional reduction in the permitted amount of fuel per lap. The quantity of fuel consumed in each lap is accounted for down to a hundredth of a gallon.

    The WEC allows engineers a great degree of freedom in terms of the hybrid drive concepts. The teams can choose between diesel and gasoline engines, naturally aspirated or turbocharged engines, various displacements, and one or two energy recovery systems.

    In this way, the regulations prevent the LMP1 cars from becoming faster, yet at the same time fuel the engineers’ efforts to generate more power from less fuel.


    Audi will start to its fifth season in the FIA World Endurance Championship (WEC) on April 17. On the 3.65 mile track at Silverstone near the UK town of Northampton, the brand will be contesting the season opener with two new LMP1 race cars.

    At last year’s event, endurance racing fans witnessed a thrilling competition, as the Audi drivers and their rivals overtook each other several times per lap. In the end, the brand with the four rings won. Marcel Fässler/André Lotterer/Benoît Tréluyer (CH/D/F) were the fastest drivers last April, crossing the finish line with a 4.6-second advantage following a nail-biting race.


    TOYOTA-GAZOO Racing also heads to Great Britain this week for the eagerly-anticipated opening round of the 2016 FIA World Endurance Championship, the 6 Hours of Silverstone.

    TOYOTA, starting its fifth season in WEC, will compete with its new TS050 HYBRID race car for the first time, taking on LMP1-Hybrid rivals Porsche and Audi as a nine-round battle for World Championship honors begins.

    In bright sunshine last year at Silverstone, the lead TS040 HYBRID completed 201 laps, or 735.3 miles, at an average of 122.1 mph including time lost for seven scheduled pit stops, during the six hours on its way to third place.

    TOYOTA has had a car on the podium at every Silverstone WEC race it has entered and expects to continue that run this weekend, demonstrating significantly improved competitiveness compared to the 2015 season.

    2016 FIA WEC Audi R18 TDI-Hybrid

    For the 2016 FIA World Endurance Championship (WEC) and the Le Mans 24 Hours, Audi has redesigned their R18 from scratch with almost nothing in common with its predecessor.

    A new Li-Ion regenerative braking storage and new aerodynamics should improve efficiency with little to no loss of performance.​

    It features even more advanced aerodynamics, the monocoque and the suspension are new, as well as many systems in the race car such as central hydraulics.

    For the 2016 racing season, the Audi LMP1 sports car is a vehicle that is more powerful and clearly more efficient than its predecessor. While the new R18 is Audi’s strongest race car to date, it consumes less fuel than any of the generations before it. About ten percent less from early testing.

    With the new hybrid system and around 1,000 hp of system output, the new R18 puts more power on track than any of its predecessors with a focus on maximum efficiency combined with high performance. The R18 now processes 50 percent more hybrid energy than its predecessor, storing it in a battery for the first time.

    2016 FIA-WEC Toyota TS050 Hybrid

    The TS050 HYBRID features a new 2.4L direct-injected and turbo charged engine combined with 8MJ hybrid system to meet the 2016 WEC regulations, which limit fuel flow and total fuel energy consumed.

    The team will use the high-downforce specification TS050 HYBRID to meet the particular demands of Silverstone high-speed, sweeping corners.

    2016 FIA WEC Porsche 919 Hybrid

    The Porsche 919 Hybrid powertrain concept consists of a 900+ hp, direct injected and turbocharged downsized 2.0L V4 gasoline engine and two different energy recovery systems that are more efficient than ever before. Although the 2016 regulations stipulate an eight percent reduction in fuel consumption, the 919 in early testing has almost equaled its lap times from the previous year at the official WEC Prologue in Le Castellet. For the six-hour race on the demanding Silverstone Formula One circuit, the prototype received aerodynamically optimized body work for high downforce in the fast corners.

    For the first time Porsche is fully exploiting the WEC regulations by deploying three different aerodynamic packages to make the car best suit to the respective race tracks.

    For 2016, the electric drive has become even more powerful and efficient. A powerful electric motor sits between the wheels up front powered by a new generation of in-house developed Li-Ion battery cells.

    The 2016 Porsche 919 chassis structure remains unchanged, as does the hybrid drive concept with its two different energy recovery systems (regenerative braking from the front axle and exhaust energy recovery).

    The 2.0L 90 degree V4 loses a bit of weight while driving the rear axle. Last season, the output of the combustion engine was well above 500 hp. But the 2016 regulations stipulate a lower amount of energy from fuel per lap and reduce the maximum fuel flow for prototypes.

    For the 2016 919, this means around eight percent less fuel and power which costs about four seconds for every lap of Le Mans. Through the new restrictions, the combustion engine has dropped to below 500 hp.

    The kinetic energy produced at the front axle when braking is converted into mechanical energy in a Kinetic Energy Recovery System (KERS) system and then converted to electricity and stored in a Li-Ion battery. The second regeneration system is installed in the exhaust tract, where the exhaust-gas stream drives a second turbine in parallel with the turbocharger. It uses excess energy from the exhaust pressure that would otherwise escape into the environment. The VTG technology used here – that is, the variable adaptation of the turbine geometry to the level of exhaust pressure – drives the turbines, even at low engine revs and low pressure.

    The additional turbine is connected to an electric generator. The electricity produced is also stored in Li-Ion battery. When the driver calls up the full-boost, additional power output of more than 400 hp will acelrate the car simailr to a 900+ hp race car. This power is applied to the front axle by the electric motor, and it temporarily transforms the 919 into an all-wheel drive car with system power of around 900 hp. For each circuit, the team works on developing the strategies for when and to what extent energy is recuperated and called up.

    Porsche 919 Hybrid

    Two energy recovery systems worth upwards of 400 hp plus a powerful 500 hp 2.0L drive last year’s Manufacturer champion.​

    Li-Ion Battery

    Initially, Porsche was using KERS flywheels and supercapacitors for storage. For 2016, they are using an 800V Li-Ion storage battery.

    The FIA WEC regulations allow four levels of power recovery and use ranging from two to eight megajoules (MJ) of deployable energy. The calculation is based on the 8.45 mile lap of the Le Mans course, and is adjusted for the other eight racing circuits. The high level of efficiency of the combustion engine, the recovery systems and the energy storage enabled Porsche in 2015 to become the first and only manufacturer to choose the 8 MJ class.

    In this highest regeneration category, an FIA flowmeter device will limit the permitted amount of fuel per lap to 1.14 gallons of high octane gasoline. Engineers also have to take into account the fact that the more powerful the energy recovery and storage systems are, the bigger and heavier they tend to be.

    Next Sunday, the hybrid sports cars from Audi, Toyota and Porsche will be meeting again in a field of 33 participants. The Silverstone season opener will be the first assessment of where everyone stands.

    Round 2 - SPA 2016 LMP1 – Audi wins, Porsche extends its points lead and Toyota has a disappointing outing

    Audi celebrated its first WEC victory of the 2016 season at the second round of the FIA World Endurance Championship (WEC) at Spa-Francorchamps. In the end only two of the six hybrid sports cars from all manufacturers that had started finished at the front of the field in Belgium. To give an idea of the challenges, Track temperatures of up to 122 degrees F were much warmer than expected for the race in the Ardennes Mountains.

    Audi R18 Turbo Diesel Hybrid


    Victory with a two-lap advantage was celebrated by Lucas di Grassi/Loïc Duval/Oliver Jarvis (BR/F/GB) in their Audi R18.

    The spectators in Belgium witnessed the most thrilling race of the season with Audi, Porsche and Toyota each leading with a clear advantage at least once during the race.

    Audi Sport Team Joest ended up the most successful.

    Lucas di Grassi started the race in car number ‘8’ before his teammate Loïc Duval, followed by Oliver Jarvis, took over. After six hours of racing with several yellow periods, numerous penalties, accidents and technical defects in the field, the trio celebrated its first joint victory.

    It was Audi’s 106th LMP success in total since the 2000 season.

    The number ‘7’ sister car driven by Marcel Fässler/André Lotterer/Benoît Tréluyer (CH/D/F) suffered several setbacks. During one of his stints, Tréluyer drove over a curb so hard that the damaged the underfloor which then had to be replaced. After the car spent over 14 minutes in the pits for this repair the air ducts had to be cleaned at a later stage, which cost further time. When Marcel Fässler touched a car in front of him, the team had to change the hood of his race car. In addition, number ‘7’ received a drive-through penalty for this incident. In the end, the driver trio battled its way forward to position five overall. As a result, Audi scored 40 additional points in the manufacturers’ classification tally.

    The next commitment for Audi Sport in the WEC will be the test day at Le Mans on June 5. There, the squad is going to prepare for Audi’s 18th participation in the 24- hour race that will be held on June 18 and 19 this year.

    Porsche at Spa

    Despite a problem with the hybrid system, the trio of Romain Dumas, Neel Jani and Marc Lieb finished second with their Porsche 919 Hybrid in Spa-Francorchamps and extended their lead in the WEC championship points tally.

    Porsche 919 Hybrid(s)


    After two punctures, the sister car of Timo Bernhard (DE), Brendon Hartley (NZ) and Mark Webber (AU) spent more than one-and-a-half hours of the six-hour race in the garage for repairs.

    The fastest lap of the race, achieved by Brendon Hartley (1:58.431 minutes). Following the season’s opening race at Silverstone this is the second fastest race lap for Porsche’s Le Mans prototype in 2016.

    Starting driver in the #1 car, Brendon Hartley built up a solid lead until his first pit stop after 23 laps. Timo Bernhard took over with fresh tires and continued in second. The number 5 Toyota took the lead after refraining from a driver and tire change. Bernhard is faster, a breath-taking battle develops between him and Sébastien Buemi. Bernhard overtakes in La Source, Buemi strikes back in Eau Rouge. Entering lap 37 Bernhard reports a puncture, having 4.3 miles to drive before reaching the pits. While bringing the car home, the tire falls apart and damages the body work. In the pits the front nose is changed, Mark Webber takes over. On lap 45 the front left tire is damaged again – a result of the first puncture. After a longer stop for repairs Brendon Hartley rejoins the race.

    When the race is 56 laps old, the number 1 car is four laps down in 14th position when the next pit stop is due. The front gearbox was damaged due to very different wheel speeds of the two front wheels when bringing the car home with the damaged tires. At 16:38 hrs local time the repair begins. At 18:17 hrs the 919 with Webber at the wheel leaves the pits again, having a 51 lap’s deficit to the leaders. He does a 24-lap stint before he hands over to Bernhard. The gap to the leaders is now 49 laps. After 137 laps into the race, Hartley jumps in for the final stint, using a safety car period. He brings the car home in 27th place overall and fifth in the hybrid class.

    Marc Lieb in the #2 car has a good start and followed his teammate in second position. After almost six laps Lieb reports a problem with the hybrid system. Car number 2 cannot use the full electric power for the remaining race distance. After 22 laps Neel Jani jumps into the handicapped car. On lap 47 he hands it over to Romain Dumas before Lieb gets behind the wheel again after 71 laps. At the end of 95 laps Lieb hands over to Jani. Despite the reduced power Dumas/Jani/Lieb are driving in third position because Audi and Toyota have problems with one car each. On lap 113 the leading Toyota number 5 has technical issues as well, Jani is promoted to second. After 118 laps Jani pits and hands over to Dumas who comes for a final refuelling during a safety car period and finishes in P2.

    Toyota at Spa

    Toyota Gazoo Racing saw potential victory slip from their grasp last Saturday with mechanical issues affecting both their cars in the 6 Hours of Spa-Francorchamps in Belgium.

    Toyota TS050 #5 in the pits


    Toyota went into the race leading the manufacturers’ world championship standings and qualified strongly, #6 Toyota TS050 Hybrid of Stéphane Sarrazin, Mike Conway and Kamui Kobayashi and the #5 car, piloted by Anthony Davidson, Sébastien Buemi and Kazuki Nakajima, claiming third and fifth spots on the starting grid respectively.

    Both cars demonstrated significantly improved performance since their last race appearance at Silverstone. The #5 had been leading by more than a minute at the four-hour mark, with the No6 in third after an earlier accident with a lapped car required it to pit for repairs.

    Engine problems for both TS050 HYBRIDs put them out of contention. The #5 of Anthony Davidson, Sébastien Buemi and Kazuki Nakajima was classified 26th, but earned 12 points in terms of manufacturers’ World Championship points. The #6 of Stéphane Sarrazin, Mike Conway and Kamui Kobayashi retired.

    Prior to the mechanical issues, the two TS050 HYBRIDs demonstrated significantly improved performance. The #5 had been leading by over a minute, with the #6 in third after an earlier accident with a lapped car required it to pit for repairs.

    The Audi, Porsche and Toyota teams next race is the Le Mans 24 Hours on 18 June, when 250,000 spectators will witness the 84th edition of the world’s most famous endurance race.
