GM resumes production of its 3.0-liter turbodiesel straight-six

General Motors temporarily stopped taking orders for trucks and SUVs equipped with the 3.0-liter Duramax turbodiesel six-cylinder engine in August 2021 due to a supplier shortage. Reports claimed the pause would last through 2021, but the engine is already back in production. Enthusiast website GM Authority learned from sources inside General Motors that the straight-six is once again coming off the assembly line at the Flint Engine Plant in Flint, Michigan. There's no official word on precisely what the problem was linked to and whether it was related to the on-going chip shortage that's wreaking havoc across the automotive industry. All we know is that the pause lasted for about two weeks. Called LM2 internally, the six is available in Chevrolet's Tahoe, Suburban, and Silverado 1500 and in GMC's version of these trucks. It's also an option in the Cadillac Escalade. It develops 277 horsepower at 3,750 rpm and a V8-like 460 pound-feet of torque at 1,500 rpm in every application, and it allows these big behemoths to post surprising fuel economy numbers. Fitted to a rear-wheel-drive Tahoe, the Duramax returns 21 mpg in the city, 28 mpg on the highway, and 24 mpg in a combined cycle, figures that make it more efficient than a Blazer. Demand for the diesel-powered trucks is relatively high. While the shortage undoubtedly took a toll on sales, the Duramax represented 8% of Suburban sales and 6% of Tahoe sales in May 2021. There are no other diesel-burning full-size SUVs available new so they have the market to themselves. On the truck side, Ram still makes the EcoDiesel available on some 1500 trims but Ford abandoned the segment.

Recharge Wrap-up: meet the Luka EV project, VisibleTesla allows Model S hacking

Select Registry is partnering with Tesla to install chargers at many of its lodgings. More than 170 hotels, inns and bed & breakfasts will install Tesla High Power Wall Connectors for their guests to use. So far, 63 properties have installed the chargers. Eventually, Select Registry members in 34 states as well as Nova Scotia will offer charging on-site. Tesla's wall charger provides the Model S with 58 miles of range per hour. The hotels will rent you a room for the full night, as well. Read more in the press release below. Tesla Model S owners can hack their car with the VisibleTesla app. The free, open source app allows users to check on and control the status of the car and its subsystems, similar to Tesla's official apps. VisibleTesla can also be used to schedule certain automated commands. For example, its creator, Joe Pasqua, has his car send him a text message reminding him to bring his bags with him when he enters the grocery store parking lot. Other users have the car remind them if the car is not charging at a certain time, or schedule the car to turn on the heat before departure.

Employees, particularly the utility's energy efficiency experts, will use the cars to travel to customers' homes and businesses to conduct energy audits. "We are leading by example and demonstrating to our customers, and other Georgia businesses, that electric transportation works for all drivers," says Georgia Power Chairman, President & CEO Paul Bowers. Georgia Power also offers charger rebates and special rates for EV customers. Read more at Domestic Fuel. The Luka EV is a project to build an affordable, lightweight, retro-looking, road-legal electric car in one year. The team wants to get the car certified for use on EU roads by September 2015. They have goals of achieving a driving range of 300 kilometers (about 186 miles), keeping the cost under ˆ20,000 (about $22,280 US at current rates) and the weight under 750 kilograms (about 1,650 pounds). The builders recently completed their first range test of the working vehicle, which uses in-hub motors for propulsion. Learn more at the Luka EV project page on Hackaday.

Race Recap: Rolex 24 at Daytona was fast and feisty

Let the record show that victory at the 2015 Rolex 24 at Daytona went to the No. 02 Chip Ganassi Racing with Felix Sabates Target/Ford EcoBoost Riley DP driven by Verizon IndyCar drivers Scott Dixon and Tony Kanaan and NASCAR drivers Jamie McMurray and Kyle Larson. The winner did 740 laps to cover 2,634.3 miles in 24 hours and 57.667 seconds. That's a statement to this year's pace in spite of 18 cautions, two more than last year: the Michael Shank Racing Ligier got pole with a time of 1:39.194, slower than last year's pole time of 1:38.270; however, the winning car last year only did 695 laps. The fight for top honors was shaved to a four-car battle over the first third of the event. The No. 02 Ganassi car took the lead on the first lap, swapping it well into the night with the No. 01 Ganassi car, the No. 10 Wayne Taylor Racing Corvette DP, and the defending champion No. 5 Action Express Corvette DP, all of them staying within about 20 seconds of one another. The Action Express car had a fuel connector come loose and lost three laps getting towed back to the pits to have it reattached, but was back in the lead 18 hours in. The No. 01 Ganassi car dropped out with recurring clutch problems 22 hours in, retiring not long after. A race-within-the-race is where the concluding action happened, a seven minute, 30-second dash from the end of the last caution to the checkered flag. During the penultimate pit stops with an hour to go, Dixon was in second place followed Jordan Taylor in the Wayne Taylor Racing DP into the pits but beat him out, taking the lead. The Action Express car was in third. In the last pit stops of the race, Dixon gained even more time, getting a four-second advantage over Taylor. Then a full-course caution came out twenty minutes before the finish when a Prototype Challenge car hit the wall and caught fire, bunching up the field. That closed the pits, but the Wayne Taylor Racing car had to pit during that yellow because of a miscalculation of driver time. No driver can be behind the wheel for more than four hours in a six-hour period but Jordan Taylor was going to go over, so he came in to swap out for brother Ricky. That cost the team any chance of second place, since they took an additional drive-through penalty for entering closed pits. When the track went green again, Sebastien Bourdais in the Action Express car stayed all over Dixon for the final five laps but couldn't get around him.
