The 2021 Chevrolet Tahoe is the most fuel-efficient full-size SUV in its class and the 2021 Chevrolet Suburban isn't far behind. Further behind are the Ford Expedition, Lincoln Navigator, Nissan Armada, and Infiniti QX80, the two chief rivals of the models.

The best-in-class figures are courtesy of General Motors' 3.0-liter Duramax turbo-dielse engine. That engine is new for the 2021 model year in the Tahoe and Suburban. Rear-wheel drive Tahoes get 21 mpg in the city, 28 mpg on the highway, and 24 mpg combined. Four-wheel drive models get 20 mpg in the city, 26 mpg on the highway, and 22 mpg combined.

Chevy's 2021 Suburban gets 21 mpg in the city, 27 mpg on the highway, and 23 mpg combined when equipped with front-wheel drive. Four-wheel drive Suburbans get 20 mpg in the city, 26 mpg on the highway, and 22 mpg combined when equipped with front-wheel drive.

The diesel power plant is the first diesel engine offered in GM's full-size SUVs since 1999. It first appeared as part of the GM lineup in the 2020 Chevrolet Silverado. In that application it quickly earned accolades for its quiet operating noise and fuel efficiency, as well as its near-immediate delivery of power.

In every application, the Diesel engine is paired with a 10-speed automatic transmission.

The 2021 Tahoe's engine gets 277 horsepower and 460 pound-feet of torque when equipped with the engine. Diesel-powered front-wheel drive models have a maximum towing capacity of up to 8,200 pounds and a max payload of 1,717 pounds. With the same engine under the hood, the 2021 Suburban has a maximum towing capacity of up to 8,000 pounds and a max payload of 1,625 pounds.

"The 3.0L Duramax turbo-diesel brings responsive torque and a smooth driving experience, ideal for those who tow or spend many hours behind the wheel," said John Barta, assistant chief engineer for the 3.0L Duramax. "Not only is the 3.0L Duramax a refined engine, but the total experience benefits from the efforts to deliver enhanced driving dynamics in Tahoe and Suburban through the independent rear suspension and available Magnetic Ride Control and Four-Corner Air Ride Adaptive Suspension."

The 3.0L Duramax turbo-diesel is available on the LS, LT, RST and Premier trims with an MSRP of $995 over the base 5.3L V8 gas engine. It is also available in the High Country trim as a $1,500 MSRP decrease over the standard 6.2L V8 gas engine.

The first customer deliveries of the 2021 Tahoe and Suburban with the available 3.0L Duramax turbo-diesel are expected to begin before the end of the year.

Domino's and Nuro announced their partnership in 2019 — and now the robots are hitting the roads.

After announcing their partnership to work on pizza deliveries via self-driving robots in 2019, Dominos and Nuro have officially rolled out their technology to one part of town.

Beginning this week, if you place a prepaid order from Domino's in Woodland Heights (3209 Houston Ave.), you might have the option to have one of Nuro's R2 robot come to your door. This vehicle is the first do deliver completely autonomously without occupants with a regulatory approval by the U.S. Department of Transportation, according to a news release.

"We're excited to continue innovating the delivery experience for Domino's customers by testing autonomous delivery with Nuro in Houston," says Dennis Maloney, Domino's senior vice president and chief innovation officer, in the release. "There is still so much for our brand to learn about the autonomous delivery space. This program will allow us to better understand how customers respond to the deliveries, how they interact with the robot and how it affects store operations."

The Nuro deliveries will be available on select days and times, and users will be able to opt for the autonomous deliveries when they make their prepaid orders online. They will then receive a code via text message to use on the robot to open the hatch to retrieve their order.

"Nuro's mission is to better everyday life through robotics. Now, for the first time, we're launching real world, autonomous deliveries with R2 and Domino's," says Dave Ferguson, Nuro co-founder and president, in the release. "We're excited to introduce our autonomous delivery bots to a select set of Domino's customers in Houston. We can't wait to see what they think."

California-based Nuro has launched a few delivery pilots in Houston over the past few years, including the first Nuro pilot program with Kroger in March 2019, grocery delivery from Walmart that was revealed in December 2019, and pharmacy delivery that launched last summer.

From being located in a state open to rolling out new AV regulations to Houston's diversity — both in its inhabitants to its roadways, the Bayou City stood out to Nuro, says Sola Lawal, product operations manager at Nuro.

"As a company, we tried to find a city that would allow us to test a number of different things to figure out what really works and who it works for," Lawal says on an episode of the Houston Innovators Podcast. "It's hard to find cities that are better than Houston at enabling that level of testing."

The all-electric range of the 2021 Volkswagen ID.4 has been confirmed. The model is the first modern electric Volkswagen to be sold in the U.S. and a model that the German automaker is resting a lot of hopes on for the future of sales in the country.

The 2021 Volkswagen ID.4 Pro with all-wheel drive will achieve an EPA-estimated 260 miles of all-electric range on a full charge. The ID.4 Pro S and 1st Edition, which have more features and equipment and therefore weigh more, achieve an estimated 250 miles of range.

The EPA-estimated fuel economy for ID.4 Pro RWD is 107 MPGe in the city; 91 MPGe on the highway, and 99 MPGe combined. The ID.4 Pro S and 1st Edition does slightly worse achieving 104 MPGe in the city, 89 MPGe on the highway, and 97 MPGe combined.

These new numbers come as part of a second round of EPA testing. Original testing found that the model did not quite hit its target.

How does that compare to other EVs? The Nissan Leaf Plus offers 226 miles of all-electric power. The Hyundai Kona Electric delivers 258 miles. Volvo's XC40 Recharge has just 208 miles of all-electric range but the Tesla Model Y can go up to 326 miles on one full charge.

First out of the Volkswagen gate will be ID.4 models with an 82-kilowatt-hour battery and rear-mounted AC permanent-magnet synchronous motor. That system delivers 201 horsepower and 228 pound-feet of torque.

At a public DC fast-charging station with 125 kW charging, the ID.4 can go from five to 80 percent charged in about 38 minutes. With purchase, ID.4 owners receive three years of unlimited charging at Electrify America DC Fast Chargers at no additional cost.

The 2021 ID.4 is on sale now, with pricing for the rear-wheel-drive ID.4 Pro starting at $39,995 MSRP, before a potential Federal tax credit of up to $7,500. The Pro S carries an MSRP of $44,495. The limited-run ID.4 1st Edition, which sold out the day the vehicle was launched, carried an MSRP of $43,995.
