2018 Volkswagen Polo revealed

"Based around the German car maker's MQB AO platform architecture, the new Volkswagen has grown quite significantly to match the dimensional gains made by many of its more contemporary compact class rivals; it boasts a 94mm longer wheelbase than the fifth-generation Polo at 2564mm, while the track widths are up by 62mm at the front at 1525mm and by 49mm at the rear at 1505mm to provide it with a considerably larger footprint than ever before.

The previous Polo was based around Volkswagen's PQ25 platform, whose engineering dates back to the fourth-generation model launched back in 2001."

The main thing for me is the update to the chassis. My 9N3 has a wide track mod to the lower control arms and on ET40 rims with 12mm spacers front and 20mm spacers rear (that's for on the track) even then only has front:rear track of 1470:1451. So the new car will have a significantly bigger footprint than mine. Only thing is the weight. It might end up a porker next to the new Fiesta ST. But that motor/gearbox combo is pretty attractive.
