Toyota Prius C vs Audi A5

What's the difference?

See if you can guess the name of the world's first ride-sharing app. You're thinking Uber, right? Nope. It was a company called Sidecar. It's broke now, shuttered for good in 2015. What about the first video-on-demand service? Netflix? Nope. Amazon beat them to it, for starters, but so did many other, now-defunct companies who tried it even earlier.

The point is, being first on the scene is no guarantee you'll be the best, or the most successful. I mean, just look at electric cars; plenty of manufacturers were doing all-battery models before (and arguably better than) Tesla, and every one of them is now parked in Elon Musk's gargantuan shadow.

Before full-electric there were hybrids, and first to arrive on that particular scene in any meaningful way was Toyota and its awkwardly shaped Prius, back in 2001. And they had that field to themselves for a while, but soon enough the other manufacturers trotted out hybrid and plug-in hybrid models of their own.

And so Toyota shook up the Prius offering, launching the seven-seat Prius V, and the bite-sized (and Yaris-based) Prius c we've tested here, in 2012, hoping to broaden the appeal of its hybrid offerings. Problem is, 2012 was an awfully long time ago, and so Toyota has waved its wand over the ageing Prius c for 2018, changing its design, tech offering and interior in an effort to keep it fresh.

So, is the Japanese giant still head of the hybrid class? Or has it been beaten at its own game?

The Audi A5 has done something naughty. It’s replaced the Audi A4.

Or at least that’s the case for now after the Ingolstadt brand made a bit of a mess of its naming strategy.

Essentially, the Audi A5 is now available as a sedan or a wagon, and the next A4 coming soon will be electric. The previous A5 was a swoopier two-door coupe or four-door gran coupe style model. So the A5 is now effectively Audi’s main BMW 3 Series or Mercedes C-Class and CLA rival.

Plus, the Audi S5 is also here to cater to performance car fans.

Can a new platform, a sleek, fresh look and a techy interior do the job?

We’ve been pedalling around the Victorian countryside in the hopes of finding out.

Stick with me, and I reckon we’ll get to the bottom of it. The question about the car, that is, not the bottom of Victoria.
