I have been researching the CV90 and Puma for a while and in my unprofessional opinion on the matter of tanks (I only know kinetic mathematics and basic tank warfare principles) I would say the CV90 fits Canada's wants and needs and will most likely be the victor unless the program is cut or the CV90 fails IED/Anti-mine testing (which, I have read in a news article is what the Canadian military is currently testing on a Risk Reduction Unit.

CV90 vs. Puma
CV90 Armament:
(Export Version)
30mm Bushmaster II Autocannon (Lack's anti-air capabilities according to experts (AHEAD rounds) only 1.24g) (200 RTF, 200 storage)
(Secondary) 7.62 Browning Machine gun (Retains the ability to shoot through some buildings/armoured cover)
(Variants)
40mm Bofors Autocannon (has anti-tank and anti-air capabilities) (24 rounds per magazine)
35/50 Bushmaster III Cannon
105mm tank gun/turret (however the odds of Canada buying this variant are about the same as Canada purchasing the MGS in my opinion)
120mm Rheinmetall (Same L55 as the Leo 2's and with the newest round available has been argued to be stronger than American Abrams DU rounds)
AAV 40mm Bofors Autocannon and can elevate gun higher
Puma Armament
30mm Bushmaster II Autocannon (Lack's anti-air capabilities according to experts (AHEAD rounds) only 1.24g) (200 RTF, 200 storage)
(Secondary) 5.56mm HK MG4 higher ROF, less penetration, crew can use ammo in personal weapons. 1000 RTF, 1000 in storage. (can be changed to MG3).
EuroSpike Spike LR missile launcher. (Needed for anti-tank/bunker kill capabilities so Canada would need to purchase these in a modern war or hope the accompanying Leo 2's kill all armour threats.)
CV90 Protection
Protects against 14.5mm armour-piercing rounds and frontally against 30mm APFSDS rounds.
Additional armour kits protects all around from 30mm APFSDS.
Unknown IED/hollow-charge defense capabilities but vehicle is battle tested and almost no casualties have been suffered with the vehicle so it can be assumed that the vehicle is good to go against RPG's since one of it's engagements encountered several RPG's. However, IED testing is on-going.
Smoke Grenade Launchers (unknown #)
Cannot make 450mm ground clearance with the stabilized 40mm Bofors gun.
Unknown Crew Survivability.
IR Suppressing Paint.
High elevation target.
Crew can be hit in the turret in the hull down position unlike Puma.
Unknown if Infantry have rear sight view.
Unknown if vehicle can equip Trophy/Quick kill systems.
Puma Protection
Protects against 14.5mm armour-piercing rounds and frontally against 30mm APFSDS rounds.
Additional armour kits protects all around from 30mm APFSDS.
Not battle tested but is "said" to defeat hollow charges.
Is said to defeat shaped charges and explosives up to 22 pounds while, retaining the 450mm clearance.
Smoke Launchers on vehicle (unknown #)
Crew compartment is one "box" so crew can "replace" each other.
Infantry can "slightly" open back door to scout/shoot from.
IR Suppressing Paint.
External Gas Tanks (good idea or bad idea? It was a bad idea on the Tiger Mk 1 in World War 2 and caused many deaths of the vehicle)
Vehicle is a low target.
Crew cannot be hurt in the hull down position as turret is unmanned.
Infantry have a rear sight view.
Designed so it can equip the Trophy/Quick kill systems.
CV90 Mobility
Speed of 70km/hr means vehicle can keep up with Leopard 2's.
Operational Range 320km.
410 kW Engine
Amazing mobility in snow and hot weather conditions. (So no matter what it can always keep up with the Leo's)
8 Troopers in back and very roomy from the looks of videos (Soldiers do not have to crawl out of the back and can simply jump out almost standing). (http://www.youtube.com/watch?v=i8PzFICkVSU)
Vehicle weighs 23 tonnes at basic weight.
Easier to transport then Puma.
Puma Mobility
Speed of 70km/hr means vehicle can keep up with Leopard 2's.
Operational Range of 600km.
800 kW engine.
6 Troopers in vehicle and soldiers practically have to crawl out of the Puma.
31.5 Tonnes at basic weight.
Unknown off road capabilities.
Designed to have Three Puma's + armour kits aboard four A400's
Capacity of the A400 is 37,000 kg while the Capacity of the C-130J Super Hercules is 19,090 kg which, can be an issue for Canada if vehicles are transported that way.
Puma "seems" to bounce while driving as if it's "hitting" waves. (http://www.youtube.com/watch?v=O3bG3x0Jwbs)
Cost of 1 CV90 = $6,524,804 CAD
Cost of 1 Puma = $11,071,500 CAD
Cost of 100 CV90's = $652,480,400 CAD
Cost of 100 Puma's = $1,107,150,000 CAD
P.S. I know this is an IFV but do you guys think this will be an Infantry soldier vehicle purchase or an Armoured soldier vehicle purchase.
It just seems like a crime against nature to buy these for Infantry soldiers while, the Armoured soldiers are using Coyotes.
Also, why do Infantry soldiers drive IFV's in the CF where all over the world IFV's are driven by Armoured soldiers everywhere else?
