Magazine Article

Whilst travelling recently I got a copy of October Classic & Sports Car Magazine to read in the lounge.

It had an article on the 75yrs of Jaguar

For 1961 it had the MK10

The couple of sentences on it read something like this:-

The substantially designed Mk10 was the 1st Jaguar to have IRS,
a wider version than seen on the E-Type.

My question here is how much wider is it

The Mk10 was a wide car too, it held the record untill the arrival
of the XJ220 Supercar.

I thought the Mk10 \ 420G was the largest Jaguar

If the XJ220 was bigger does anyone know its spec

Luxuriously appointed with swathes of wood on the dash, picnic tables &
door tops. It was a popular in the states as built mainly for the US market.
