It was just a few weeks ago that General Motors was getting razzed online for admitting that they didn't have a fully functional prototype of a vehicle that they already were accepting reservations for.

Now, an operable version of the long-awaited 2022 GMC Hummer EV has been spotted at GM's Milford Proving Grounds to continue the validation process before it heads to northern Michigan to endure the winter testing process.

GM says that the Hummer EV's development speed was "enabled by extensive virtual testing" which will "be a hallmark of GM programs moving forward". Automakers and tire companies have extensively been using digital simulation technology. Pirelli recently explained that they used digital simulations to test the Scorpion ATR tires that were specially designed for the 2021 Ford F-150.

Production of the Hummer EV is expected to begin in the fall of 2021. The first models off the line will be part of the Hummer EV Edition 1 series. It's set to deliver 1,000 horsepower, has a 350-mile all-electric range, and goes for $112,959.

That version of the truck will come with a 200-kilowatt-hour battery back. That battery is attached to two motors at the front and one at the rear producing 1,000 horsepower and 11,500 pound-feet of torque. Other forthcoming Hummer variants are set to have unique powertrain setups.

GMC has given each Hummer EV four-wheel drive allowing it to have CrabWalk mode, which utilizes torque vectoring technology. When activating that mode, the Hummer EV to move diagonally.

It also allows the truck to have a launch mode called "Watts to Freedom". It allows the Hummer EV Edition 1 to travel from zero to 60 mph in three seconds.

Inside, the Hummer EV is minimalistic but effectively designed. In front of the driver is a 12.3-inch digital gauge cluster while a 13.4-inch infotainment screen sits in the center of the dashboard. The two screens are powered by Epic Games' Unreal Engine, the same architecture that Fortnite runs on.

The automaker is putting its Super Cruise hands-free driver assist technology on every Hummer.

New driver assist technology is coming to the Lexus lineup later this year.

New Lexus Teammate driver assistance technology will debut on the 2022 Lexus LS 500h later this year. Its availability is constrained to all-wheel drive models.

The technology was developed based on the Mobility Teammate Concept. This automated driving concept is unique to Toyota sough to enhance communication between drivers and cars, "enabling them to reach out to each other for mutual assistance". The concept sees cars and humans interacting and partnering rather than having automation take over for drivers. This approach allows drivers to enjoy the experience of driving but allowing the vehicle to take over some functions of driver's duties at times. In this way, the tech works as both guardian and chauffeur.

2022 Lexus LS 500h

On the 2022 Lexus 500h, Lexus Teammate will offer two functions: Advanced Drive and Advanced Park.

Advanced Drive is design to "accurately detect driving conditions to plan and execute acceleration, braking, and steering commands to maintain the vehicle within the lane, follow other vehicles, change lanes, navigate certain interchanges and traffic jams and overtake slower vehicles." It's a Level 2 functionality that "allows for driving on limited-access highways with partial hands-free, eyes-on-the-road operation".

This description makes it sound a lot like the suite of lane keeping, lane centering, and adaptive cruise control technology that Hyundai offers rather than true Level 3 technology that General Motors's Super Cruise delivers.

Advanced Park operates similar to how the Genesis GV80's hands-free parking assist technology works. The Lexus tech automatically controls steering, acceleration, braking, and gear changes with parallel parking or backing into a parking space. It uses a combination of 360-degree sensing technologies and a bird's eye view display to perform the task while allowing the driver to monitor progress.

"We are very proud of Lexus Teammate, which is the culmination of five years of close collaboration between our technical centers in Japan and the US. We conducted simultaneous development and rigorous testing in both markets with the goal of achieving industry-leading advanced driver assistance functionality," says Derek Caveney, executive engineer at Toyota Motor North America's Integrated Vehicle Systems team.

The 2024 GMC Hummer EV SUV is set to arrive on U.S. lots in the spring of 2023.

When it debuted over the weekend, GMC promised that the 2024 GMC Hummer EV SUV would be packed with "tactical technology". Today, the company is giving a more in-depth look at what technologies you can expect to see in the SUV when it finally makes its way to U.S. dealerships in early 2023.

"GMC's Hummer EV SUV offers an exceptional balance of on-road performance and off-road capability, enhanced by a unique structure that allows for our signature open-air experience," said Al Oppenheiser, Hummer EV chief engineer. "New features debuting on the SUV reinforce its role as a tactical tool in almost any situation."

Among the new technologies are trail mapping, an available Power Station generator, Extract Mode, and CrabWalk. They combine with the Hummer EV SUV's dimensions, which make off-roading hospitable, to create a compelling vehicle, at least on paper.

Think of this tech as trail navigation plus energy monitoring all in one. The redesigned myGMC app allows users to plan and navigate off-roading adventures while keeping an eye on charging locations and their distances fro off-road locations. This all results in a community-based energy forecast. Routes and plans can be downloaded from the app on the driver's phone and projected on the vehicle's infotainment screen to be used while driving.

"It's technology that adds to the Hummer EV's immersive driving experience," said Mike Colville, senior manager for EV complex feature integration and execution. "More than simply locating a destination, we help you find an epic one, create an EV-unique navigation experience when you get there and allow you to share your trip with others."

Once pushed to the in-vehicle system, the Hummer EV SUV's 13.4-inch infotainment screen and 12.3-inch driver information display share the appropriate information in the correct places for easy use.

Cameras everywhere 

From the same company that brought you 15 different camera views in the 2020 Chevrolet Silverado comes the available technology known as UltraVision. UltraVision offers 360-degree high-definition views with 14 camera views standard and up to 17 camera views the available underbody cameras that come on the Extreme Off-Road Package.

Selective power allocation

The Hummer EV SUV is nine inches shorter than the Hummer EV pickup. That allows it to be more maneuverable, with a turning circle of just 35.4 feet and four-wheel steer. That turning circle is tighter than what the Ford Mustang Mach-E and Toyota RAV4 offer.

The SUV's platform allows for 13 inches of suspension travel while climbing up to 60 percent grades, scaling 18-inch verticals, and fording water more than two feet deep. To do this, the Ultium drive system is able to allocate all the SUV's power to one wheel or split it between several.

This power allocation ability also enables the SUV's CrabWalk mode. Standard on 2X, 3X, and Edition 1 models. CrabWalk enables diagonal drive functionality.

Extract Mode

GMC is touting the Hummer EV SUV's adaptive air suspension with Extract Mode. Though details are scant on what Extract Mode may entail, the general thought around the industry is that it will be something similar to Mercedes-Benz's Free Driving Assist. That Merc tech is an off-road mode that helps drivers get free when they've managed to get their SUV stuck in sand or mud via a bouncing effect.

An onboard power generator

GMC will offer the Hummer EV SUV with generator technology that is similar to what Ford already offers in the F-150. The available Power Station generator enables 19.2 kilowatts of AC charging, generator functionality (120v/25A/3kW), and ability to charge other EVs (240v/25A/6kW). The Ford model's Pro Power Onboard system offers 7.2 kilowatts of charging capability. Earlier this year, theHyundai Ioniq 5 was teased with similar technology.
