CAT new products: 319 excavator, 150 - 160 graders, D8 XE dozer

Caterpillar presented three main updates at CONEXPO 2026 in Las Vegas. The lineup includes a new excavator size, two upgraded motor graders, and a new electric drive dozer.

List of new products presented by Caterpillar at CONEXPO 2026:

• Cat 319 compact radius excavator (new 19 to 20 ton class)
• Cat 150 and Cat 160 motor graders 
• Cat D8 XE electric drive dozer 

Caterpillar 319 compact radius excavator 

Cat 319 sits between the Cat 315 and Cat 325, in a 19 to 20 ton class Caterpillar did not cover before. This matters because many contractors end up "oversizing" into a 325 just to get stability and lift, even if they do not need that much machine for transport and tight sites.

Caterpillar built the Cat 319 on the Next Generation platform and centered it on a wider 2.8 m undercarriage. The goal is simple: more stability and lift confidence, while staying inside a 3.0 m maximum transport width. Key capability notes from the launch details:

• Supports TRS17 rotation work tool attachment
• Can run a variable angle boom or blade options
• Delivers up to a 7% lift capacity boost compared to the 317
• Supports a 1 m³ general duty bucket option

Cat 319 key specs 

Caterpillar 150 and 160 motor graders 

Caterpillar is moving Cat 150 and Cat 160 into the Next Generation platform that started with the 120 and 140.

What is actually new (based on launch details):

• Nine-speed transmission, with a new finish gear for precise final passes
• Redesigned cab with larger windows (visibility focus on moldboard and tires)
• 10-inch touchscreen that integrates optional tech like Cat Grade, 360 cameras, and People Detection
• Cat 150: joystick or lever controls
• Cat 160: joystick standard

Cat 150 vs Cat 160 specs 

Next, let’s turn that into a clean choice framework, because "150 vs 160" is often decided in a messy way on site.

Caterpillar D8 XE electric drive dozer

The Cat D8 XE is described as Caterpillar’s second high drive electric drive medium dozer, following the D6 XE.

How the D8 XE electric drive works 

Instead of a conventional torque converter transmission:

• A Cat C15 engine drives a generator
• The generator powers an electric motor (through an inverter) connected to the final drives

IVT’s show report adds more detail:

• Fully sealed, liquid-cooled generator
• Two separate cooling circuits (engine coolant and power electronics)

Buying Caterpillar heavy equipment from Makana

If you are researching Caterpillar heavy equipment updates like these, do not stop at one spec line. A better workflow looks like this:

Step 1: Research specs like a buyer, not a fan

Use Makana’s specs hub and reviews first:

• Check machine class, operating weight, reach, depth
• Compare configurations and options
• Watch operational videos and look at high quality photos

Start here: Technical Specifications on Makana and expert reviews.

Step 2: Compare machines side-by-side

Once you shortlist, use the comparison tool for fast checks:

• 315 vs 319 vs 325 class logic
• 150 vs 160 grader fit
• Standard D8 vs D8 XE productivity goals

Step 3: Decide how you want to buy: direct sale or auction

Auctions are not only for bargain hunting. They are often the cleanest way to see real market demand. If you want the auction route, then review the buying and selling process.

Step 4: Filter by category, then by brand

To browse in a way that matches how people actually search:

• Excavators for sale
• Bulldozers for sale
• Cat machines

Step 5: Use inspection proof to reduce risk

Makana’s model includes:

• 3D virtual tours
• certified 75+ point inspections (including diagnostic methods such as Jaltest V9)

That combination helps you catch expensive surprises before the machine lands on site.

If you want to keep your decisions grounded in specs and inspection proof, use makana.com to research, compare, and then choose between direct purchase and auctions using real listings and verified machine reports.

FAQ

1) Is the Cat D8 XE a battery electric dozer?

No. The D8 XE uses an electric drive system where the diesel engine drives a generator that powers an electric motor. It does not require charging like a battery machine.

2) What does "compact radius excavator" mean in real jobs?

It means the upper structure swings in a tighter envelope, so you can work closer to traffic, walls, and obstacles. It is most useful on tight urban sites, utilities, and road work.

3) What is TRS17 on the Cat 319 and why do contractors care?

TRS17 is a rotation work tool attachment type referenced in launch coverage. Contractors care because rotators increase precision but add weight and leverage, so stability and lift capacity become critical.

4) What is the fastest way to compare Cat 150 vs Cat 160 for grading work?

Compare three items first: moldboard length (12 ft vs 14 ft), control setup (joystick standard on 160), and your finish-pass requirements. Then check the jobsite visibility and camera options you need.

5) Which single spec matters most when comparing excavator classes like 315, 319, and 325?

Start with operating weight (tonnage). It drives stability, lift performance, and how attachments behave in real work, especially with tilt rotators and heavy buckets.
