Need another reason to swing by the Alami Proton carnival this weekend? Well, we’ve got three very good ones – aside from the fact that you’ll be getting a glimpse of the Proton Pick-up Concept, that is. Anyway, back to the topic at hand. For the 2015 round of its open day exhibition, local car manufacturer Proton has decided to parade three of its Malaysian Touring Car race machines.

We begin with the Proton R3 Suprima S and its Preve sibling. The race-ready Suprima S is equipped with a naturally-aspirated 1.6 litre Campro IAFM four-cylinder engine that puts out a total of 155 hp at 7,500 rpm and 185 Nm of torque at 4,000 rpm. Said mill gets paired to a close-ratio five-speed dog box transmission.

Other changes include the adoption of a unique lightweight body shell and a six-point roll cage. Also, the fuel tank has been repositioned to the boot for purposes of improved weight distribution while the driver’s seat has been moved closer to the centre of the car for better visibility.

The Proton Iriz R3 Malaysian Touring Car, on the other hand, employs a reworked 1.6 litre Campro CFE engine sans the turbocharger. Total power output is rated at around 190 hp while the mill itself is mated to a five-speed dog box transmission.

Additional modifications to the cabin include a competition-ready, spartan interior, a six-point roll cage, Sparco steering wheel, Tonnka pedal box and Recaro Pole Position race bucket seats. Also, the Iriz R3 is equipped with Alcon racing brake callipers and Ohlins adjustable coilovers. All those modifications were certainly worth the cost and time as the racer won on its debut at Round 4 of the Malaysia Championship Series (MCS).
