Designed to add a sporting edge to the hitherto demure hatchback and replace the understated T180 model, the new SR version features a lowered suspension set-up from Toyota Motorsport and a rear spoiler.
A set of 17-inch five-spoke alloys are also included, as is tinted rear glass.
The main difference, however, is the 2.2-litre D-4D diesel engine.
It will make 175bhp and 295 lb-ft of torque, which can propel the car to 62mph from standing in 8.1 seconds, while it can still come up with impressive returns of 45.6mpg.
Vehicle stability control (VSC) with traction control is provided as standard, as is dual-zone air conditioning, automatic headlights and wipers and cruise control.
The SR180 is available now in both three and five-door form, priced from £17,995.
