Hi Martin - I know you have the Touareg and I'm sure it's a great car but even the Tiguan has grown wider by 16 cm in the new version which might not seem a lot on the open road but will be a squeeze to get into the garage. VW are now setting themselves alongside Audi in terms of price but the cars are virtually identical under the body shell. I'll be surprised if the VW wins this contest even if its media technology is superb - it will run the apps on your smartphone on the internal screen so if you want to use Google Maps instead of the in-car satnav then you can.
I'm hoping to get adaptive cruise control so if the car in front slows down the system recognises this and keeps you at a safe distance - great for motorway travel and a step towards self drive cars. I'll write reviews after the test drives.
