Supercars teams will be equipped with engines per category from a single supplier per manufacturer under Gen3.
KRE Race Engines and Mostech Race Engines were commissioned to develop the new generation Chevrolet Camaro and Ford Mustang engines, respectively.
Once homologated by the Supercars, the engines will be produced in bulk by the respective manufacturers and will then be pooled before being distributed to the respective teams.
Under Gen2 regulations, crews have several options for powering the engine.
Walkinshaw Andretti United builds its own engines through its Walkinshaw Racing division, which also supplies Erebus Motorsport.
KRE Race Engines supplies Brad Jones Racing as well as Triple Eight Race Engineering and its client teams Team 18, Team Sydney and Matt Stone Racing.
Tickford Racing and Kelly Grove Racing build their own engines while Dick Johnson Racing is supplied by Mostech Race Engines.
However, under Gen3, each brand will have a designated engine supplier.
Speaking to Speedcafe.com, Adrian Burgess, Motorsport Manager at Supercars, explained the new process.
“First of all, we’re obviously going to go through the process of these guys [KRE and Mostech] submitting engines to us, ”said Burgess.
“We’re going to run the two side by side and split up against each other. We have a few outputs that we want to equate to as peak horsepower, but then we have things like torque, torque maps, we have fuel mileage, we have CoG (center of gravity), we have a. cost – all of these things that we are going to paritate and make sure they are very similar to each other.
“But the rationale at this point for using both manufacturers is that it’s about saving money for the class and at the moment we have five engine builders who all make similar products. You just don’t get economies of scale. It is more difficult to stay on top of reliability when several people are doing the same thing.
“The process will be that they will build their engines. We’ll have an engine homologated, then they’ll build the engines, give them to Supercars, we’ll do one last dyno check and just reduce the last percent of the horsepower, then lock it out. This engine will be locked and we Supercars will allocate. This engine will go there, this engine will go here, this engine will go there.
“All GM engines and all Ford engines, there’s only one engine pool and Supercars are just going to allocate where they go in which car so nobody thinks they have anything better or worse than someone else.
“This is what was agreed on paper during the meetings. Obviously, we need to sit down and put more details on it. It’s just a level playing field for everyone in terms of the engine they get.
Burgess thinks there is little need to have more than one engine maker per brand, let alone three on the Ford front.
Switching to a single supplier per brand will reduce costs, increase reliability and be easier to control. There are also parity considerations since there will be fewer engines to balance.
While several teams have dedicated engine build shops, Supercars CEO Sean Seamer said he was “not sure they’ll want” to build engines under Gen3.
“The cost of engines has been going down so far,” Seamer said.
“Mostech and KRE are the ones doing all the work and development on these engines with Ford and GM respectively.
“Never say never, but it’s an essential part of launching a new car. All you’re going to do is introduce the risk of failure by putting off this stuff.
“Certainly, as we move forward in development, launch and production, Gen3, putting these cars on the grid, it will be Mostech and KRE.
“If in the long run KRE and Mostech decide they’re ready to supply components to other racing teams, that’s great.
