Le Mans 24h was the perfect event to conclude WEC superseason 2018-2019.  LMP1 class has been entirely dominated, as expected, by Team Toyota with the 2 TS50 that started from front grid and challenge each other during the entire race. As is often the case also this edition has been decided during last hour, due to a puncture revealed on car #7 that in reality has been discovered to be a malfunctioning of TPMS System (Temperature and Pressure Monitoring System) that constantly control pressure and temperature inside the 4 tyres.   Result of LMP2 class has been more uncertain during the marathon with a very intense race pace. Enso CLM P1/01 run Le Mans using the same ...

6H at Spa Francorchamps will be surely remembered for the incredible weather conditions, never seen so far on the long WEC Superseason 2018-19.  Despite sunny starting after 3 minutes all turn into a rainy and snowy race, difficult for the drivers and challenging to keep strategy in phase with constantly changing track conditions. Toyota TS050 take another victory, never in discussion in term of performance but challenging for the low grip conditions.  As we outlined several times in these aero analysis the area behind front splitter and aside front keel is very crucial to guide the flow managing the effect of front tyre turbulence and vortex.  Enso CLM P1/01 shows ...

WEC 2018 season is moving forward providing clear figures about Toyota TS050 supremacy on LMP1 class. No discussion about flying lap capability, reliability and race pace consistency so far, nevertheless last race at Silverstone has offered an unpredictable results. Toyota TS050 Hybrid n. 8 , the winning car driven by Fernando Alonso, Sébastien Buemi and Kazuki Nakajima, as well as sister car .7 were found to be in non-conformity of Article 3.5.6.d of 2018 LMP1-H Technical regulation that cover permitted deflection of the skid block. Rebellion R13 n.3 take victory after Toyota exclusions following post-race scrutineering (with Steward’s decision n. 25 and 26). Nowadays ...

BR1 is certainly an interesting actor of LMP1 non-Hybrid group with a design that appears quite sophisticated since its first unveiling at Al Sakhir circuit in Bahrain. This prototype has been design and developed by Dallara for BR Engineering and takes advantage from the design experience gained on the LMP2 car. LMP1 technical rules, especially on the aero side, provide more room on splitter area that in turn means higher downforce and efficiency with surfaces design that is all but simplified. Comparing low downforce kit (SPA - Le Mans) with high downforce configuration is always an interesting exercise. On BR1 the research of lower drag , thanks to less downforce demands, turn ...

Le Mans 24h qualifying sessions clearly confirm the performances level noted since collective practice sessions at Paul Ricard and first event of WEC super Season 2018/2019 at Spa Francorchamps circuit. Reference car is undoubtedly Toyota TS50 that could be considered almost without competitors on Lmp1 class, thanks to long participation to WEC and available resources, significantly larger than all other teams. Fortunately reliability is still to be verified for all competitors, this will be key factor since winners at Le Mans were not always the fastest cars. We are only few hours ahead from getting answers to several considerations made by enthusiasts during last months. Meanwhile ...

Le Mans 24h weekend is getting very closed and beside Toyota, BR/Dallara and ByKolles there is another interesting LMP1 car to be reviewed, namely Ginetta G60-LT-P1. Presented in January during Autosport International at Birmingham, model G60 named as tribute to 60^th anniversary of UK brand located at Leeds, is an interesting interpretation of the LMP1 technical rules. It is powered with Mecachrome V6, 3.4 litres with nearly 650 HP and will be primary actor competing on LMP1 privateer title. Ginetta G60-LT-P1 is adopting a rather conventional cooling ducts system for brakes. Front ducts are designed with recessed scoop located just over the splitter on fender inside surface. ...

Spa Francorchamps race weekend was as usual a good proving ground to test low downforce aero package to be adopted at Le Mans. We take opportunity to review here Rebellion R13, primary actor competing on LMP1 privateer title. Interesting to see how they will perform at Le Mans, competing with Toyota hybrid TS050. It is known that Rebellion R13 is built around Oreca 07 chassis, and Gibson GL458 engine. At first look the car from outside has same philosophy as the Oreca 07, but there are several changes from front to back creating different airflow management on external aerodynamics as well as cooling. Rebellion R13 rear fender is more conventionally designed with very slender ...

Porsche, despite his withdrawal from WEC, has developed his 919 Hybrid focusing on maximising his performance in unique experiment to challenge laptime record at Spa. This gave motorsport community the great opportunity to compare LMP1 and F1 performance. Last occasion during 2017 Prologue in Monza has proven F1 to be faster, (1’30’’547 marked by Lapierre on Toyota TS050 vs. 1’21’’135 Hamilton pole position on Mercedes W07). But it is essential to remark that regulations changes during winter 2016 made F1 3-3,5 second faster and LMP1 nearly 4,5 second (at Le Mans) slower than previous racing season. Porsche 919 Evo driven by Neel Jani marked an impressive ...
