GLOSSARY
MGU-K: motor generator unit – kinetic
MGU-H: motor generator unit – heat
ERS: Energy Recovery System (referring to the unit as a whole)
MJ: Mega Joules, so 1 million joules.
Joule: unit of measurement of energy, knowing that 1000 joules = 1 kW
(so 1.34 hp over a second), 8 MJ = 10.738 horsepower over a second.

I’m still lost in the insanity that there will be 4 factory backed P1 teams at Le Mans this year. And they’re all so wildly different implementations of the rule book. If only Peugeot had stuck around to give us a 5th.

arent there some differences between which power sources drive which wheels?
would be interesting to include.

Knew most of it, but that was a great all encompassing post. Thanks.

I thought the porsche had more top speed this year? then again spa & silverstone are a different animal

Audi R18 e-tron quattro:
Engine: 4.0l turbocharged diesel V6
Layout: Mid-engine, rear-wheel drive
Hybrid Energy Class: 4 megajoules (per La Sarthe lap)
Hybrid Storage: GKN Hybrid Power flywheel motor-generator unit
Hybrid Harvesting: Front axle kinetic motor-generator unit
Power Output: Claimed >558 horsepower from engine, plus >272 horsepower from ERS, resulting in claimed peak total of >830 horsepower (actually: probably 1000)
Porsche 919 Hybrid:
Engine: 2.0l turbocharged petrol V4
Layout: Mid-engine, rear-wheel drive
Hybrid Energy Class: 8 megajoules
Hybrid Storage: Liquid-cooled A123 lithium polymer battery pack
Hybrid Harvesting: Front axle kinetic motor-generator unit, turbocharger-mounted thermal motor-generator unit
Power Output: Claimed >500 horsepower from engine, plus >400 horsepower from ERS, resulting in claimed peak total of >900 horsepower (reality: probably 1100)
Toyota TS040 Hybrid:
Engine: 3.7l normally aspirated petrol V8
Layout: Mid-engine, rear-wheel drive
Hybrid Energy Class: 6 megajoules
Hybrid Storage: Nisshinbo supercapacitor bank
Hybrid Harvesting: Asymmetric front and rear axle kinetic motor-generator units (Aisin motor in front, Denso motor in rear)
Power Output: Claimed peak total of >986 horsepower (reality: again, probably 1100)
Nissan GTR LM NISMO:
Engine: 3.0l twin-turbocharged petrol V6, built by Cosworth
Layout: Front-engine, front-wheel drive
Hybrid Energy Class: 2 megajoules expected
Hybrid Storage: Torotrak contra-rotating flywheel assemblage
Hybrid Harvesting: Front axle flybrid clutched transmission
Power Output: Claimed 550 horsepower from engine, plus 700 horsepower expected from ERS, resulting in claimed peak total hopes of 1250 horsepower
Differential Strengths & Weaknesses:
Audi:
Strength: Downforce / aerodynamic grip, cornering speeds,
Strength: Repairability, modularity,
Weakness: Straight-line speed
Porsche:
Strength: Sustained hybrid power, straight-line speed,
Strength: Fuel efficiency,
Weakness: Reliability, complexity
Toyota:
Strength: Mechanical grip, tire efficiency, reliability,
Strength: Burst hybrid power,
Weakness: Numerical disadvantage at Le Mans, slight overall pace disadvantage so far
Nissan:
Expected Strength: Low drag, high straight-line speed,
Expected Weakness: Lack of experience, possibly reliability, ? Wild card !
I like the Claimed peak total & probably figures.

In theory, they do.
But Audi heavily improved the aerodynamics this year, compensating for a less powerful propulsion system.

You know, if they routed the exhaust to the front wing instead of making you eat it, they’re gonna get a bit more downforce, sorta like exhaust-blown diffusers.
EDIT: Wait that won’t work at all.
