Undoubtedly eager to improve the take rate of electric vehicles, automakers have a myriad of solutions at their disposal. But the majority have something to do with getting the government involved to futz around with taxes.

Normally, this has to do with making special exceptions for EVs or subsidizing them via rebate programs. But governments seem happy to do this, as increasingly more legislation is advanced that would place restrictions on when and where people will be able to drive internal combustion vehicles, and automakers appear to be getting with the program. We’ve already seen manufacturers choosing sides in America’s gas war and now the Europeans are getting in on the action by demanding higher taxes be imposed on vehicles reliant on gasoline or diesel.

Hi Sajeev,

You are my go-to guy for in-depth automotive knowledge. (Wow! Honored. – SM)

My brother has been having a heck of a time with his 2012 Mazda3 Skyactiv. It’s got about 70k miles on it, and in the past 2 years it’s been in and out of the shop. It started with high engine oil consumption (more than a quart per 3k miles, and going up to this day). Then the ignition coils needed to be replaced. Then the MAF and oxygen sensors needed to be replaced. Right after those were fixed, he had to take it back to the shop because there is now a misfire in one of the cylinders.

What’s going on here? My only guesses are worn piston rings causing engine oil to run into the combustion chamber (then down the exhaust and ruining the O2 sensor), or malfunctioning PCV, a broken EGR system, intake valves with a lot of carbon deposits, or simply “bad luck” with this car.

Hope you are able to shed some light on this mystery. Thanks! (Read More…)

Sajeev,

I have a 2003 Jetta TDI with 178k miles. Runs 100%. My mechanic recommends a carbon cleaning. What are the positives and negatives? To be more succinct, what can go wrong?

After months of intense lobbying, Germany has convinced European Union environmental ministers to keep 2020 new car carbon dioxide emissions standards at 130 grams per kilometer instead of the proposed, stricter 95g/km standard. The German government argued that the tighter regulations would cost jobs and hurt German automakers. BMW and Mercedes-Benz produce larger and heavier cars than other European car companies like Fiat and Renault and they would have a more difficult experience trying to meet the new CO2 standards.
