Driving a 600bhp tuned Toyota GR Yaris (and how it was modified)

Driving a 600bhp tuned Toyota GR Yaris (and how it was modified). And it's still 1.6 litre! This is thought to be Europe's most powerful Toyota GR Yaris, with over 500 wheel horse power and over 600 at the flywheel. It was built by established Supra mk4 2JZ speed shop Garage WhifBitz in Monmouthshire, who were a known tuner back in the Max Power days.

Jonny Smith finds out all the mods that make this GR Yaris double its factory power without exploding, then drives the sequential gearboxed fiesty 4WD on the road (in rain).

I had to skip the video right to the dyno because I thought this was absolute bollocks but lo and behold it's the real deal... Absolute madness!

[darrenprior]

600hp in this. I've got one but only mildly tuned to 300hp and 400nm and it's an absolute weapon. Just came back from a drive with a bunch of Porsches and Lambos and happily carved them up through the mountains. I cannot imagine what this monster would be like

[Sinnistral]

312bhp/litre is pretty fierce, but 166bhp per cylinder is utterly mental 😍. But the rain Jonny, the rain! You need to offer up a sacrifice to the horsepower gods or something 😜

[richardsmiths]

I remember the days when 200hp in a "small" car was groundbreaking. 😂

[martycrush]

My mate has just traded an M2 in for his GR. he absolutely loves it. He’s had some beautiful motors in his time and this has brought a smile to his face more than any other👏🏻

[markthibault]

With that kind of power, I think I might prefer a full cage. What a beast! Thanks for sharing, Jonny!

[jackboulter]

An awesome hot hatch, definitely my favourite of them, but this one is simply epic. Plus, it's done very subtly, and I love the addition of the sequential gearbox, and I can't believe that it's still only a 1.6 litre. Credit to Toyota for making such an amazing engine.

[zohircherifi]

I would have a GR Yaris over a Golf R everyday

[mickmcc]

Fair play to you, Jonny. You’ve big brass balls to be driving a pocket rocket so hard in those conditions. The thing is a missile

[arsalaanosman]

"Incredible thrust from such a small displacement" Thats what she said.

[chadderton]

When I see a GR on the road it gives me the same feeling as when I used to see Integrales. Such a muscular, compact little beast. Can't imagine what this would be like to drive. And that shifter!

[ericvermeulen]

I think a modest 350-380hp should surely be an absolute hoon to drive

[ptbfrch]

I think Koenigsegg Gemera has a 2 litre 3-cylinder with the same output, using their free-valve tech. To do that with a 1.6 is absolutely crazy. Very impressive!!!

[christianbliss]

I shall never tire of GRY content. Once again Jonny, this is automotive nerd heaven. And 100k well spent!

[Milenu]

It's worth a revisit in better conditions and closed road/track.

[ewanstewart]

I’m glad you like the 3 cylinder engines, I had a go in a Corsa 3 pot once sounded great, I followed a Fiesta ST 3pot the other day and it was epic but that thing is otherworldly wow 👍🏻

[CalumRaasay]

I think the GR Yaris is my new attainable dream car, such amazing little things.

[mugenmark]

GR Yaris owner here. Got a few bolt ons but think I need to pay a visit to Whiffbitz. What an incredible overengineered motor that 3 pot is!

[sebastiend.]

Forget electric cars, it's amazing how far we've come with petrol engines.
3 cylinders for Chris' sake!

Greetings from the Netherlands

Toyota could add icing to their kudos ratings by offering tuning packs on these. 260mhp standard, 300, 350, 400bhp packs. We would flock to Toyota for the upgrades.
