LMH has been launched as a alternative for the LMP1 class, in a bid to scale back prices on the high finish of endurance racing and enhance its enchantment to automotive producers, after the likes of Audi and Porsche withdrew to depart Toyota as the one OEM remaining.
Toyota launched its GR010 HYBRID for the beginning of the 2021 WEC season, whereas the US-based boutique producer Glickenhaus added its non-hybrid 007 LMH to the sector in time for the second spherical in Portimao.
There’s nonetheless an LMP1 automotive within the sequence, with Alpine fielding its ORECA-designed A480 (previously the Insurrection R-13) by way of a “grandfather” clause within the guidelines that permits non-hybrid LMP1 equipment to race on.
However what are the similarities and variations between LMH automobiles and their counterparts in Method 1? Let’s have a look.

Which is quicker: an F1 automotive or an LMH automotive?
F1 automobiles recurrently surpass 200mph, however to date in 2021 the best pace throughout a race clocked within the championship has been 216.9mph, courtesy of Lando Norris at Paul Ricard. Nonetheless, larger velocities are anticipated from races at Monza and Mexico Metropolis, the place the automobiles have considerably much less downforce owing to Monza’s high-speed structure and Mexico’s excessive altitude.
WEC has already visited Monza this yr, with the best pace throughout the Monza 6 Hours belonging to the Glickenhaus automotive of Romain Dumas, who hit 197.3mph. This was matched by Pipo Derani within the different Glickenhaus automotive and Brendon Hartley within the #8 Toyota throughout the third free apply session.
Speeds will probably be larger on the lengthy straights of the Circuit de la Sarthe at Le Mans: Louis Deletraz hit 217mph in Hyperpole final yr behind the wheel of a Insurrection-Gibson R-13. However the brand new LMH formulation has considerably elevated the load of the top-line class of automobiles — the Toyota GR010 hits the scales at 1040kg in contrast with 878kg base weight for LMP1 hybrids — and peak energy is down for the automobiles operating vitality retrieval, so high speeds ought to come down compared with final yr.

How a lot horsepower do LMH and F1 automobiles have?
With twin energy-retrieval techniques augmenting the 1.6-litre V6 inside combustion engine in an F1 automotive, a 2021 F1 automotive produces an output of round 1000bhp, though this quantity is never confirmed by any of the powertrain suppliers inside the class.
The LMH guidelines units a cap on the entire horsepower, 520kW or 670bhp, from all parts of the powertrain within the curiosity of guaranteeing open competitors. Nonetheless, engine design is open, permitting producers to decide on their configuration and displacement. Power restoration techniques are optionally available, though the deployment of hybrid energy is regulated to get rid of any unfair benefit over non-hybrid automobiles.
The hybrid system will be applied inside the entrance axle for an all-wheel drive configuration, and can regenerate vitality expended from front-wheel braking. This hybrid system might not have an output of greater than 200kW (268bhp).

What assists can be found for F1 and LMH automobiles?
F1 automobiles at present incorporate a drag discount system (DRS), permits the driving force to open the rear wing to negate the consequences of drag when following one other automotive and have a higher probability to overhaul. That is restricted, in a race state of affairs, to a automotive inside one second of the automotive in entrance. Drivers have been previously allowed to vary engine modes throughout a race, however this was restricted partway by way of final season to permit drivers use of only one engine map throughout each qualifying and the race.
The LMH guidelines now not enable hybrid energy for use as a push-to-pass overtaking instrument: the ability curve is outlined for every automotive within the Stability of Efficiency desk for every race. Energy from the entrance axle also can solely deployed above 120km/h (roughly 75mph) to make sure there is no such thing as a traction benefit for four-wheel-drive automobiles out of lower-speed corners.

What is the distinction between the WEC and F1 qualifying codecs?
F1 qualifying takes place over three elements; Q1, Q2 and Q3. Q1 lasts 18 minutes and options all 20 automobiles making an attempt to set the quickest laptimes. The slowest 5 automobiles are eradicated and set of their grid slots, whereas Q2 then options the remaining 15 automobiles. Q2 lasts quarter-hour, and as soon as extra the slowest 5 automobiles are eradicated and the highest 10 progress to the ultimate half – wherein pole place is determined together with the grid slots all the way down to tenth place.
The highest 10 can even begin the race on the tyres on which they logged their quickest Q2 lap, however have free tyre selection for Q3 to try to set a time ok for pole inside the 12 allotted minutes.
WEC has a extra conventional system system comprising two 10-minute periods, one for the Hypercar and LMP2 lessons, and one other for the GTE divisions: the quickest lap from every qualifying driver units the grid. Some extent is awarded to every of the drivers of the automotive that takes pole within the 4 lessons.
The double-points Le Mans 24 Hours WEC spherical runs to a unique format referred to as Hyperpole, which was launched final yr. The highest six automobiles in every of the 4 lessons throughout a 45-minute interval on Wednesday, the primary day of qualifying, go ahead to the half-hour Hyperpole session on Thursday.

What are the variations between WEC and F1’s race codecs?
Method 1 races last as long as a most of two hours excluding any pink flag stoppages, and are run to the shortest race distance exceeding 305km, barring the Monaco Grand Prix which runs to round 260km. Throughout the race, every automotive should use a minimum of two of the three nominated tyre compounds supplied by Pirelli, and pitstops might solely be used for tyre modifications and attainable repairs following the ban on refuelling from 2010 onwards.
WEC races are for much longer, therefore the time period “endurance racing”, and nearly all of races final six hours. There are two eight-hour races on the 2021 calendar, on the Algarve circuit in Portimao and the second Bahrain race on the finish of the season, whereas Le Mans lasts a full 24 hours.
The minimal length is 4 hours, a format tried within the 2019/20 season.
Because of this a number of drivers share every automotive, and there are rules throughout every class that mandate minimal occasions behind the wheel for every driver. Endurance racing additionally assigns every driver a class – bronze, silver, gold and platinum – based mostly on prior expertise and outcomes, and the LMP2 and GTE Am classes have set combos of driver categorisations allowed. This doesn’t apply to the Hypercar class, aside from allowing no bronze drivers to take part within the class.

What is the distinction between F1 and WEC’s factors techniques?
For a six-hour race, WEC runs to the identical 25-18-15-12-10-8-6-4-2-1 factors format as F1, albeit with a half-point accessible for automobiles ending beneath that in every class. It additionally awards a degree for every class pole.
WEC treats every class as a separate championship, and awards factors to a crew relative to their place inside the class.
The eight-hour races and the Le Mans 24 Hours provide completely different factors distributions. In an eight-hour race, the factors are handed out in a 38-27-23-18-15-12-9-6-3-2 format for the highest 10 with one level on provide to finishers beneath that. Le Mans runs to a 50-36-30-24-20-16-12-8-4-2 format, double the factors on provide for a six-hour race.
In contrast to the WEC, Method 1 awards a degree for the quickest lap of the race, supplied it has been set by a driver inside the high 10 on the chequered flag. There is no such thing as a level for pole place, nor for drivers ending beneath tenth.
