In the October edition of 911 & Porsche World there's a comparison test between the A110 and 718T. Overall a very good comparison but no surprise that in a Porsche magazine the Cayman wins. There is no real criticism of the Alpine in any area, the summary being;
The Alpine gives the Cayman a serious run for its money and for some it will be the better car. The Cayman has key advantages, a more charismatic engine, an optional manual gearbox and 911 grade hardware at a knockdown price.
In the comparison chart the Alpine is quicker to 60mph than the Cayman by 0.8 seconds, is 327kg lighter, costs £4,351.00 less and is more economical.
In my view an article well worth a read.
