A version of this post originally appeared in Refactoring , a Substack offering advice for software engineers. I think their existence is what explains the curious durability of the notion of a 10x engineer, someone who is 10 times as productive or skilled as their peers. At one point, I was a pretty good database reliability engineer.
The US Environmental Protection Agency (EPA) is granting two waivers of preemption regarding four California Air Resource Board (CARB) regulations related to California’s heavy-duty vehicle and engine emission standards. In this instance, CARB requested two waivers for regulations relating to heavy duty vehicles and engines.

When I reviewed the new Forester last year , I had a few gripes. It should be up on torque too, but Subaru doesnt provide a figure as it asserts there isnt a standardized method for calculating total system torque output in hybrids yet. Maybe it should, because a hybrid drivetrain is exactly what the non-Wilderness Forester needed.
The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology. First, it contains very little sulfur.
ZeroAvia secured the permit to fly following an extensive ground testing campaign and a rigorous review of the full development program. Part 21 is an industry-standard term used to describe the regulatory approval of aircraft design and production organizations, and the certification of products, parts, and appliances for aircraft.
The mid-sized five-seat SUV can cover up to 180km on electricity before reverting to its petrol engine. Its a lot of combined electrical power and theres still an engine to come into play, too. litre turbocharged petrol engine musters a modest 110kW and 230Nm. The front motor makes 130kW and the rear motor 135kW.
As part of the application process, manufacturers must demonstrate through testing that a vehicle meets applicable emissions standards and disclose to EPA all auxiliary emission control devices (AECDs) and any defeat devices installed in the vehicle.
NuScale Power announced that through further value engineering efforts, using advanced testing and modeling tools, NuScale analyzed and concluded that the NuScale Power Module (NPM) can generate an additional 25% more power per module for a total of 77 MWe per module (gross), resulting in about 924 MWe for the flagship 12-module power plant.
This fuel-cell-propelled LNG carrier eliminates the need for internal combustion engines by replacing the ship’s propulsion and auxiliary engines with fuel cells running on non-combusted natural gas. We will lead the international standardization of fuel cell propulsion systems.
In researching this review an entirely routine request for clarification on current ZS pricing was put to MGs media people. Standard Excite gear includes LED headlights and daytime running lights, 17-inch alloy wheels, fabric seat trim, single-zone climate control, dual 12.3-inch MG ZS Hybrid+ Excite.

and the Turkish contractor Rönesans Turkmen to engineer and construct the facility. Unlike DME, methanol and ethanol, synthetic gasoline meets existing gasoline standards so it can be used as a drop-in fuel. Synthetic gasoline is a competitive alternative to refinery gasoline and new energy carriers.
Once the battery is flat, the three plug-in hybrids can only drive 11-23km in engine mode before they overshoot their official CO 2 emissions per km, T&E estimates. While carmakers blame customers for using the engine too much, the PHEV models on sale today often lack the necessary EV power, range or charging speed, T&E argued.
