Cooling to pose biggest challenge in 2014
16 August 2013 – Mark Smith and James Key, technical chiefs at the respective Caterham and Toro Rosso teams, have backed up Red Bull counterpart Adrian Newey by claiming that cooling will pose the biggest challenge under the sport's new regulations.
Next season, the current V8 powerplants will be replaced by turbocharged V6 units, with the size of the required air coolers playing a major role in the packaging of cars.
He added: "The charged air cooler, for cooling the air from the turbo before it goes into the engine, will, on all of the installations, be quite significant. Physically, the size of the thing will dictate the packaging of everybody’s cooling systems. That’s the biggest single thing, I think, that’s presented itself as a challenge in terms of the overall car architecture."
Key shared Smith's sentiments, adding that very few cooling techniques will be carried over from 2013 machinery due to the significance of the rule changes.
"The cooling requirements are completely different," he explained. "You’ve got a turbocharger with a charge cooler on it, you’ve got a much larger energy recovery system (ERS) which naturally pumps out more heat, and you’ve still got your gearbox, hydraulics, oil and water to cool. You want to package that in the tidiest way you can. There are new technologies involved in all of this - it’s not stuff you can carry over."
