New entrant Aston Martin and WEC stalwart Toyota have🎃 both b💧een allowed to run their Le Mans Hypercars at 520kW below 250km/h — the maximum permitted under the regulations.

For Toyota, this marks a 12kW increase compared to last year, when its GR010 Hybrid finished second and fifth in the French endurance c🍒lassic.

Defending Le Mans winner Ferrari has been handed a 4kW power increase, raising the 499P’s ꩵoutput from 508kW to 512kW.

BMW’s M Hybrid 💦V8 has received a 2kW bump to 510kW, while both the Alpine A424 and C﷽adillac V-Series.R have been brought up to 517kW.

There is no change for t🐠he Porsche 963, which retains its 511kW output. Peugeot, meanwhile, has been hit with a minor 1kW reduction, dropping ᩚᩚᩚᩚᩚᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ𒀱ᩚᩚᩚits base power to 517kW.

Above 250km/h, stage-two power adjustments have also been applied. BMW will benefit from a 2% power increase beyond this threshold, with Porsche r🦩eceiving a 1.4% gain.
