Someone is in the car for these tests, a shift schedule is typically provided for manual transmissions.

The tier 2 standards are for light and medium duty passenger vehicles, as well as light duty trucks. The EPA classes light duty trucks by payload capacity, less than 4,000 lbs. to be exact. The max payload of the 2500 is 3,160 lbs with the Cummins engine. I think that standard would have applied to the 2500 for…

Today’s Lincoln tech tip, brought to you by Lincoln tech, is all about limited slip differentials...

I think you misunderstood my comment, the warranty does not figure into it. From the factory, real world emissions do not matter. I can get infinite emissions per mile in the real world on every diesel vehicle by idling in park. Emissions standards are applied to a defined test cycle, not real world driving. The…

There are 50,000 mile standards and 120,000 mile standards. The Tier 2, Bin 8 standard at 120,000 miles is 200 mg/mile. I think that is the standard the lawsuit refers to.

The relevant rule would be Section 203 (a)(3)(b) of the Clean Air Act, which states: “The following acts and the causing thereof are prohibited...

I think that the shift schedule is altered for the rest of the drive cycle after the 15% steering wheel angle condition. It is illegal because any feature that changes how emissions control systems function during conditions not present in the test cycle must be approved by the regulatory agency. It is possible that…

Anything that functions differently during the test cycle than in other conditions must be disclosed to CARB. It is up to the agency to allow it or consider it a defeat device. The justification for the skip shift is that it will reduce emissions during low load operation, the conditions for doing so were reviewed and…

“...certain Honda and Acura ILX models with lane keeping assist systems and built-in front radars.”

“even while the vehicle is parked and ignition is off.“

I promise, if you try to pick a fight with people in traffic in Florida, you do not get a dented fender...

Believe it or not, but I have (once upon a time) used my car as regular transportation.

So the moral of the story is, the guy driving that truck merging onto the highway probably does not have any hands on the steering wheel. Leave some room for him maybe.

Autopilot and auto-braking are distinct software features because they do different things, they use different logic. If auto-braking uses the same logic as autopilot it will maintain speed and change lanes, not something you want from a feature with “braking” in the name. What questions do you have?

I am an emissions engineer for an automotive consulting firm. I work in Detroit, but the company is global and does work for almost all the major automakers. I want to clear up a few common misconceptions that come up whenever articles get published on emissions regulation.

It also depends on what you need your car to do. The 275 HP from my last commuter/cruiser, a 1997 Cadillac Deville, was far more than I could ever reasonably/legally use. However, on a closed track I have hit the top end of the aforementioned Hellcat and found myself wanting more.

Is that the new F1 qualifying scheme?

It’s a valve. The difference is an electromagnet pushes it open instead of a cam. It will behave just like the valves already used in diesel and gas engines, it just gives us (engine designers) more control... lots more control... we like control.

You guys keep saying the water is corrosive, which is true of water in general, but completely unrelated to the problem in Flint.

I bought a 1997 Cadillac Deville two years ago. Yep, bad choice from the get-go. I have replaced brake calipers and lines, half shafts, and most of the cooling system (the rest is scheduled for replacement over the weekend.) It has had a dead cylinder for the entire time I have owned it because the dealer I bought it…
