There's not enough room in the engine bay for a four-cylinder unit.
It seems the recently introduced Twingo GT will remain the cream of the crop for the model’s current generation because Renault says it’s “almost impossible” to come out with a full-blown RS version. According to Patrice Ratti, the man in charge at Renault Sport, slapping the RS badge on the Twingo would imply at least 150 hp.
While it’s technically possible to squeeze so much power from the turbocharged 0.9-liter engine, it would require a major redesign and that would prove too costly for an A-segment hot-hatch. Taking out the three-cylinder engine to replace it with a larger four-cylinder is not a possibility because there’s simply not enough room in the engine bay for it. That would have been the cheapest way to create a Twingo RS, but it’s not going to happen due to space limitations.
If we were to read between the lines, Patrice Ratti’s use of the word “almost” could mean Renault is leaving the door open for an RS. After all, let’s not forget Renault Sport did develop a Twin’Run concept equipped with a mid-mounted 3.5-liter V6 engine serving as a nice tribute to the R5 Turbo.
But let’s not disregard the GT version, since at least on paper it’s shaping up to be a very fun little machine with 110 hp delivered to the rear wheels through a manual gearbox. It’s going to complete the 62 mph (100 kph) sprint in less than 10 seconds and will wear a slightly more aggressive body compared to the regular version.
Renault will have the Twingo GT on sale this winter, with pricing to be announced closer to launch.
