Testing how much POWER performance cars really have! PT 2

It’s time for an almighty hot hatch dyno test!

We’ve got our hands on four of the most popular hot hatches you can buy in 2023, and we’re about to find out just how accurate the manufacturers’ performance figures are in reality!

So let’s look at the line-up. First up it’s the Volkswagen Golf R, which is powered by a 2-litre 4-cylinder turbo engine that can apparently put down 320hp and 420Nm of torque. Next up it’s the BMW, with a 3-litre straight-six turbo under the bonnet that’s good for 374hp and 500Nm.

Third in the line-up is the Audi RS3 saloon. It comes with a glorious 2.5-litre 5-cylinder turbo, which is good for 400hp and 500Nm. And finally, we have the most powerful car in the line-up, the AMG A45 S. It’s equipped with a 2-litre 4-cylinder turbo which should be producing 421hp and 500Nm.

Will any cars outperform their claimed figures? Or even worse, will any underperform?! Stick with Mat for this dyno drag race to see for yourself!

I'm the owner of the AMG A45S. It turns out that after investigation by Mercedes that the car had a faulty cooling pump, which has just been changed and car is being tested by the AMG experts. fingers crossed full power will be restored!
But despite the disappointing results, it was a great day and was a pleasure to meet Mat, the team and the other car owners!
Fingers crossed i can bring the car back to another CARWOW video in the future, running the full power!

It would also be interesting to see a video of old cars to see how much horse power they still have after many years.

Would love to see a drag race between all these cars after they have been on the dyno. To see how the differences on the dyno carries over...

08:06 It was at this moment Zain realised that Matt did not want to shake his hand.

[Presto_]

You have to do this with that Merc A35 sometime. That was just bonkers quick in that drag race despite the owner saying it was stock.

Torque delivery at rpm vs weight is pretty important in how quick a car feels.

8:05 mugged him off with the handshake 🤣🤣🤣

[zyneeee]

def need to get another A45S on the dyno

[anidudee]

im ngl this is prolly one of the best inclusions on carwow other than the drag races fr!

[TotallydubbedHD]

We now need to do this now with older-gen cars. I've got an E46 M3, would love to see it on the dyno + compared to other vehicles :)
Great video, and props to all the owners!

Please talk about wheel HP! This is what really matters! The "adjustment factors" used are unlikely to be very accurate. Either way, keep it up! I love watching dyno runs and the weight of cars!

[T-Bag]

This is a great little series. Keep these coming.

[NZsarge]

I’d be keen to see another A45S on the dyno for confirmation be that’s way off, the other three though were impressive 👍🏼

[DENZELADIBOSS]

I don't feel that bad about the M240i, once I remember it's meant to compete against the S3 and A35

[DaBawski]

It's funny because I am planning to put stage 1 ECU tune on my Astra GTC at Onyx Performance because they are literally around the corner from my house, seeing Mat at their garage gives me even more confidence in these guys!

[armschoolc]

LOVE this dyno drag series!! Please keep more coming

[JJ-sxde]

One thing I like with this video Matt went straight to the point 👍

[milind]

Keep doing these dyno races, lot of fun to watch and for sure has very useful real info

This is a fantastic addition to the videos already on the channel

Need some supercars and electric cars on there! Also older cars and how much do they lose over time

[bigsmoke]

This is literally the best series you made keep it up👍🏻
