When Audi launched its A3 saloon, I remember thinking it was a bit niche and pointless. How wrong I was.

Instead, Audi has proved ahead of the curve by launching a baby saloon which, by all accounts, has been very successful.

Then, last year, BMW revealed its 1 Series saloon exclusively for China, though the model is expected to reach other markets eventually.

And now, Mercedes has finally caught up, having revealed its A-Class concept at the Shanghai motor show. It'll certainly make production, according to sales and marketing boss Britta Seeger but not until next year or maybe even the year after.
