My 14' GTI manual has the "touch" ignition, I don't have to hold down the key. Maybe it was something they changed during the MK6 era?
push to start. it is called push to start. The 2013 and some 2012 GTI's have it. 2013 and beyond all have push to start. Both R's and GTI's.
I am a physical key type of guy. Physical keys have magical properties... My 2017 BMW has push to start, and I don't really like it, it's kinda cool and convenient (contact-less access) but it's a key fog hack waiting to happen.
Push to start cars are easier to steal BUT! if you drive a VW or any other EURO car, it's A LOT harder for thieves... it's the JDM cars that are easily stolen. This is a fact.
Even with push to start, you still get a physical key... it's usaully inside the remote/key fob device... so I personally think it's a marketing thing and to make the car seem more modern... IMO.
