Proton S70 R3 S1k race car teased – Is that the sound of an NA engine?
Back in February this year, Proton announced that it will enter the Sepang 1000km (S1k) endurance with its new sedan, the Proton S70. Now, Proton has released a teaser video of the Proton S70 R3 S1k racecar and it has sparked curiosity on the internet – especially concerning what engine it has.
If you didn’t know it, the M Production (MTC) category which Proton usually competes in rules out any form of forced induction. That means no turbochargers and superchargers are allowed. The engines also have to be withing the displacement of 1,401 cc to 1,600 vv.Thus, if the rules for the race category does not change, the Proton S70 will have to source a naturally aspirated engine from elsewhere.
From the teaser video shared by Proton, we can see the development team testing the car on the dyno as well as on Proton’s test track. We also get to hear the sound of the engine, which suggest something without forced induction. The transmission in use also looks like a dogbox type.
As for its appearance, the Proton S70 racecar is still livery-less and looks like a clean prototype racer at this stage. It is however, equipped the rear wing, black wheels, stripped-out interior, and roll cage. The hood also seems to get a pneumatic strut to perhaps make servicing easier.
In the teaser video, Proton Deputy CEO Roslan Abdullah is shown sitting in the passenger seat as the S70 is taken around the Proton test track for a few laps. The development of the car is headed by the Proton R3 division which is now housed under the Proton Global Services (PGS) subsidiary.
Proton Cars’ latest social media post reads, “Sleepless nights, endless weeks, months of toil. Witness what happens when passion, skill and the spirit of racing come together to create a brand new racing car from a legendary team!”
