Textron's Tactical Armored Patrol Vehicle (TAPV) get improved mobility...

Defense News reported in April that Textron's TAPV failed a series of tests last year, forcing the company to go back and make design changes to the wheeled vehicle it is offering Canada.
"We did a true bottom-up systems engineering look and evaluated every single aspect," Gelpi said. "We're confident we have all of the issues licked."
The testing at the Nevada Automotive Test Center ended in late May, although additional tests are expected in coming months.
Canadian Department of National Defence spokeswoman Ashley Lemire said deliveries of the first TAPVs are expected to start in early 2016. Gelpi said that should occur in March but could begin sooner.

Interesting.

I thought that this would be a relatively simple procurement project.  They selected what was essentially an off the shelf design and one that has been in service with the US Army for years.

Having said all that this was a rather strange requirement to me.  The Canadians already operate the LAVIII and are moving to the LAV 6.0.

What does the TAPV bring that those two vehicles don't?
