The overhaul in rules for 2026 will affect both powertrain and chassis design, with a near-50/50 split in power delivery from the internal combustion engine and the hybrid unit - which no longer includes the turbo-mounted MGU-H.
With the increased reliance on hybridisation, the powertrains will be heavier in 2026, although the chassis is expected to lose weight through being shorter and 10cm narrower than the current specification of cars. Aerodynamicists will also get to experiment with active aero to improve the on-track racing product.
