Peugeot Activity has exposed additional information and facts about the powertrain it will use in its challenger for the forthcoming Le Mans Hypercar course from the 2022 Entire world Stamina Championship season.
The petrol/electric hybrid drivetrain is dubbed Peugeot HYBRID4 500KW. As the title implies, 500Kw – that’s 671bhp – is on offer, from a two.6-litre twin turbocharged ninety-diploma V6 petrol engine. The mid-mounted unit weighs 165kg – for reference, the 1.6-litre V6 electric power units in System 1 have a least bodyweight of 150kg, even though this also incorporates the vitality recovery systems. The Peugeot’s V6 sends travel to the rear wheels via a 7-speed sequential transmission.
The petrol engine is backed up by an electric motor driving the front axle. This generates 268bhp and is run by vitality saved in a 900-volt battery sitting appropriate in the centre of the auto, between driver and V6, and beneath the gasoline tank.
Right before the race, this battery can be billed by using a plug. When it is on monitor, vitality is recovered via regenerative braking, made possible by a brake-by-wire program which will allow the motorists to regulate the bias between electric engine braking and a conventional hydraulic set up of discs and pads on the fly.
When the mixed output of these units is 938bhp, the new rules in the Entire world Stamina Championship Hypercar course point out that only a greatest of 671bhp is at any time utilized. In most circumstances, the petrol unit will therefore operate at 402bhp, with the relaxation of the electric power equipped by the electric motor.
Electric motor utilization is forbidden less than 75mph – this is to protect against a 4-wheel travel traction gain more than autos constructed to the competing LMDh polices, whose hybrid powertrains are rear-wheel travel only – so the petrol engine can run at a increased output at decreased speeds. The V6 can also provide the entire 671bhp when the hybrid battery is depleted.
The tech specs follow on from a collection of sketches which expose the wild aerodynamic offer that the a few-time 24 Several hours of Le Mans-profitable outfit could operate. However, it also shows that Peugeot road auto cues, like the claw-like a few slash lights units front and rear, will also aspect.
The new hypercar polices imply the autos will develop relative to the LMP1 rules at the moment in position in the top rated tier of WEC types. The five-metre over-all size is 35cm extended than LMP1 polices allow, though the width is up 10cm to two metres.
Talking of the announcement, Peugeot CEO Jean Philippe Imparato claimed: “Le Mans is the holy grail of the car globe. We are coming back again to endurance racing because we have the option to work the activity in a diverse way, with the hybridization of fuel and electricity.”
Peugeot Activity will start out entire tests towards the end of 2021, with powertrain bench tests and simulator work underway previously in the yr.
