I seem to remember that in one of the MMC communiques they commented that when designing the new chassis there was scope to fit various powertrains in the future built in. I read that as
1. Ease of changing powertrain in future, based on not needing major chassis changes.
2. Allowing use of the chassis for Plus4/ 4/4 range thus enabling economies of scale for chassis supply.
Who knows.........?
Speaking to Steve Morris at TOTH he described the HUGE crash test costs they incurred. So using the now tested chassis for more volume makes sense for that outlay alone.
I look forward to the test drive impressions posted here.
