The lack of urea injection doesn’t seem to be the problem here. Lots of the cars with this defeat system have an SCR system (w/ urea injection) for handling NOx emissions (Passat, which pre-2015 is considered their “Gen2” system in the letter to VW from CARB, and all the 2015 models). A friend of mine had the idea…

Dunno... this drug for malaria is no joke (though it’s not really a vaccine, but I’d say there’s a reasonable chance this dude is confused): https://en.wikipedia.org/wiki/Mefloquin…

The issue is development time and cost. The German companies you listed have enormous powertrain R&D budgets compared with Jaguar Land Rover. I believe most, if not all, of their diesel vehicles in other parts of the world have been powered by Ford/PSA engines prior to the Ingenium engine development, and actually I…

Yes, although I think JP-8 is the preferred fuel source. Aside from some cold start issues, in lab conditions making the rated power with JP-8 isn’t usually too hard (probably requires some injection timing advance), but in practice JP-8 (and some other jet fuel variants) have no specification for cetane number, so…

In this case it’s true. While adding a turbo allows you to recover energy from the exhaust gas that would otherwise have been wasted, this usually doesn’t result in efficiency gains in spark-ignition engines where knock is a major consideration. To achieve the super-high specific output (hp/L) levels for these engines…
