and from this page http://achatespower.com/achates-power-and-cummins-develop-leap-ahead-capability-for-the-us-army-ground-combat-fleet/ some info on this engine:

Quote

A joint development team from Achates Power and Cummins Corporate Research and Technology has been running at full throttle for over a year to develop an opposed-piston Advanced Combat Engine (ACE) for the U.S. Army.  The engine is part the US Army’s 30-year strategy to modernize tactical and combat vehicles.

After several years of technology demonstrations and an intense competition, the Army kicked off the path to production by selecting the Achates Power / Cummins team last summer.  This $47.4 million contract through the National Advanced Mobility Consortium propels the 1000 HP 4-cylinder ACE variant to Technology Readiness Level 6, which will make it suitable for in-vehicle and real-world testing.

In March, our single-cylinder test asset passed an aggressive 80-hour durability test; and, the Army displayed a scale model of the engine at the Association of the United States Army’s Global Force Symposium and Exposition in Huntsville, Alabama.

Several big milestones are coming up:

• October 2018: A full-scale show model of the engine will be on display at the 2018 AUSA Annual Meeting and Exposition.
• November 2018: The joint Achates Power and Cummins development team will present initial engine testing results to the Army.
• Mid-2019: The ACE engine will present a technology demonstrator – TRL 6 (Technology Readiness Level).
• Mid-2020: Demonstration in a US Army combat vehicle.

There is a lot of work to be done.  The funding that the Army has planned will deliver Low Rate Initial Production of the first ACE variant in 2022. To fully realize the benefits of this architecture we’ve started plans for additional variants, and we are working with the platform teams and military OEMs to make sure that spiral insertion is primed as the variants come on line.  All of this while focusing on and flawlessly executing the ACE program.

A powerpack featuring the ACE engine will deliver double the power density of any existing Military-off-the-shelf powerpack at half the cost.  This kind of capability does not currently exist, and will enable vehicle optimization for survivability, package, range, and lethality that has previously never been possible.  Until the selection of the Achates Power / Cummins team, the Army has not had a plan to feasibly execute such a game-changing engine.

The Griffin II that is GDLS's MPF contender has the modified Abrams turret and a 105mm gun.

 

The 50mm gun on the Griffin III can elevate to 85 and depress to -20 degrees. It's GVW is just under 40 tons. The hexagonal camo tiles are called called Tacticam and are made by Armorworks. The turret's size is a result of the 50mm ammo. The turret is also equipped with Iron Fist APS, Switchblades and an MX-GCS sight.

Not 120mm? The main gun should be the XM1202's XM360, not the XM35 or that 105mm Cockerill gun...unless GDLS settled for a smaller-bore gun since the last AUSA.

Same one as in Skylancer's post above.

and photo of what appears to be some other version of Stryker

[Ramlaen]

The U.S. Army has awarded General Dynamics Land Systems a $383 million contract modification to upgrade 173 more Stryker flat-bottom vehicles to the A1 configuration....The Army is in the process of pure-fleeting its Stryker brigades with A1 vehicles. The Stryker A1 vehicles produced under this contract modification will complete the Army's 4th Stryker Brigade and begin the 5th Stryker Brigade.

What are the other new features of the M88A3 ?

UPDATE But putting armor around a passenger cabin that big adds a lot of weight, making the Lynx the heaviest of the three vehicles at almost 50 tons. Talking to reporters this morning, the Army’s NGCV director didn’t comment on specific vehicles, but he raised general concerns about all-new designs and about heavier vehicles — and Lynx is both the newest and heaviest of the three contender. “We would like to field this vehicle by 2026,” Brig. Gen. Ross Coffman said. That puts a premium on proven systems. If, instead of adapting existing designs, a company tried designing something from scratch specifically for NGCV, he said, “it’d be great but i don’t know that’s doable.”  Coffman also doubted that any vehicle could carry a full nine-soldier squad and adequate armor without being too cumbersome for roads and bridges for many places he’s seen in Poland and Korea, two major potential warzones. “It gets really big and heavy,” he said, (and) the infrastructure doesn’t support a heavy vehicle.”  “We’re looking at everything as options,” Coffman continued, “(but) the idea is we have a smaller vehicle that is lighter, but survivable.” If the choice is between buying one heavier vehicle that can fit a full infantry squad or two lighter ones that can each carry half a squad, it sounds like the Army would go light. That puts a heavy burden on Rheinmetall and Raytheon to prove Lynx is not too heavy — or to start shaving tons.
