You see, powering the Yaris is a 1.6-litre three-cylinder turbocharged engine, whereas the BMW uses a 3.2-litre naturally-aspirated straight-six. Or, if you’d prefer, twice the engine capacity — albeit with time and turbocharging working against it.
So, we’ll take a look at the M3 first then. Its engine produces 343hp and 356Nm of torque, dumped entirely to the rear wheels through a six-speed manual gearbox.
It definitely has a power advantage over the Yaris, as you may expect. But, the difference isn’t all that huge – the hatchback produces 261hp and 360Nm of torque. The Yaris also uses a six-speed manual, albeit delivering power to an all-wheel-drive system.
Crucially though, the GR Yaris weighs a fair bit less than the BMW M3 — tipping the scales at 1,280kg and 1,570kg.
Of course, numbers can tell a different story from reality sometimes, so you’ll have to watch to find out if half a new horse can keep up with an old stallion…
