Jaguar is planning production feasibility studies of up to 2000 cars a year for its new 780bhp C-X75 supercar, according to sources.
Jag is remaining coy about firm production plans for the elegant mid-engined C-X75, but Autocar sources say that two levels of production are under consideration. The higher one is up to 2000 cars a year, the lower one up to 1000 cars a year.
Each needs to be explored independently because they demand different production methods — the lower number with more hand assembly and lower tooling costs, the higher one with more automation, but higher tooling costs.
A production version faithful to the gas turbine-powered C-X75 will also have to wait between five-and-seven years while Jaguar proves and productionises the Bladon Jets micro gas-turbines at the heart of the hybrid-electric powertrain.
“We’re talking two-to-three years for implementation of the gas turbine technology, then another three-to-four years to integrate into a vehicle,” says Jag’s head of advanced powertrain Tony Harper.
The cost of developing the gas turbines for production could be in the C-X75’s favour, being significantly less than an equivalent IC engine, running into the “tens of millions”.
Harper is also confident the gas turbines can be engineered and proven to rigorous car industry reliability and endurance standards: “There’s much less to go wrong; there’s about 100 times fewer parts in a gas turbine than an IC engine.”
The load duty-cycle of the gas turbine will also be less harsh over its lifetime, being characterised by steady running at 80,000 rpm, rather than the ever-changing rev pattern of an IC engine.
Replicating a production supercar faithful to the C-X75 design is largely dependent on these gas turbines, because they take up such little space in the engine bay that Jaguar has been able to position the cabin 300mm further back than typical in a conventionally-powered supercar.
