In a Rally Car, the is always a crew of 2. The Driver to drive the car, and the Co-Driver to help navigate.

But what does the Co-Driver do?

Navigation is the obvious answer, but there is a lot more to that job that you might expect.

In this video our Co-Driver, Max Crouch, explains all that goes into being a Rally Co-Driver.

Subaru's Nürburgring 24-hour race was epic!

They crushed it, finishing 32nd out of 160 and first in class. 🤯

Can't wait to see what's next for the STI!

Maybe an official announcement about the next STI???

Subaru's secret to all-wheel drive?

It's all about the boxer engine and that unique drivetrain setup!

But it means longer cars to meet standards.

Symmetrical All-Wheel Drive is the Key to make the STI work?

But how can they make their whole range of cars more efficient?

Here is your SubaNews for the third week of May 2026:

The STI NBR Challenge had a great run at the Nurburgring 24 Hour race last weekend, and we talk about the results.

Subaru has announced that they are changing their plans for their fully in-house developed EV's, but could this be why we saw the STI Performance-B concept at the end of last year?

Subaru has patented an active sway-bar. Every time Subaru files a new patent we have to take a look at it, and this one is actually pretty interesting.

Last but not least, we give you a quick update on the progress of our Pikes Peak car. Were we able to get the Delta ABS to work?

Subaru's DCCD: Easier done than said!

They tried to explain it, but let's just say it wasn't simple.

Think it's easier to do than explain?

Subaru's secret weapon? This new BRZ rally car might just be it! 😉

See how this drivetrain could change everything for their passenger cars.

What if this makes the BRZ and WRX/STI even better?

Would you drive it?

Think small cars are making a comeback? Think again!

The 41 sq ft rule means tiny cars struggle to meet MPG standards.

Guess this is why Subaru isn't making them? 😉 Lots of important information to talk about here!
