<\/a><\/p>\nIt will be the fourth generation of car used in the championship, following the FT-40, FT-50 and FT-60. As before, the chassis is supplied by Italian race-car manufacturer Tatuus, continuing a relationship that began in 2005.<\/p>\n
Updated chassis and aerodynamics<\/p>\n
The GRF-70 uses a carbon-fibre composite monocoque with an aluminium and Nomex honeycomb structure. It is built to FIA safety standards and incorporates a halo, reinforced structures, updated crash protection and a front anti-intrusion panel.<\/p>\n
Toyota says the car\u2019s aerodynamic package has been influenced by current Formula One design thinking. It produces more downforce than the FT-60 but is also intended to create a cleaner wake, allowing following cars to remain closer through corners.<\/p>\n That should help overtaking, something that will be further assisted by the push-to-pass system introduced to the championship in 2026. Toyota claims push-to-pass contributed to a 30 per cent increase in overtaking during its first season.<\/p>\n Double-wishbone suspension with pushrods is fitted at each end, accompanied by two-way adjustable Andreani dampers. The braking package uses PFC discs and pads, while the wheels measure 15 inches in diameter and are shod with Pirelli control tyres.<\/p>\n Weight-wise, Toyota New Zealand mentioned that the car sits below 700kg with fluids, but without a driver.<\/p>\n Toyota turbo engine produces 212kW<\/p>\n Power comes from an evolution of the 2.0-litre turbocharged and direct-injected Toyota 8AR-FTS engine used in the outgoing car.<\/p>\n The FIA-homologated engine produces approximately 285hp, or 212kW, and drives through a Sadev SL-R 82 six-speed sequential gearbox. A limited-slip differential and Magneti Marelli paddle-shift system are also standard, while MoTeC supplies the engine control and data-acquisition systems.<\/p>\n Toyota quotes a top speed of 260km\/h and a 0-100km\/h time of 3.1 seconds.<\/p>\n The GRF-70 will also run on Fu3L synthetic fuel. The championship says the fuel produces a 77.4 per cent reduction in well-to-wheel CO2 emissions compared with conventional petrol.<\/p>\n As with the previous cars, the GRF-70 fleet will be prepared centrally by Toyota Gazoo Racing New Zealand at Hampton Downs. Engines and gearboxes will also be maintained in-house, with each car shaken down before the season to check reliability and performance parity.<\/p>\n A season costs $396,000 plus GST<\/p>\n The 2027 series guide<\/a> lists an indicative arrive-and-drive cost of $396,000 plus GST per driver. That works out to $455,400 including GST.<\/p>\n The package covers the chassis and engine leases, team fee, testing, series registration and entry fees, season consumables, tyres and insurance, although an insurance excess may apply.<\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n
