It seems like a lifetime ago now, but I actually got a patent back in my engineering days for an algorithm to detect aquaplaning as part of ABS systems.

2015 Chrysler 200C V6, Finally a Real Midsize Competitor

2015 Chrysler 200C 01

When Chrysler unveiled the new 2015 200 midsize sedan at the Detroit Auto Show last January, the team from Auburn Hills was clearly trying to expunge the final remnants of the company’s lost decade under first Daimler and then private equity ownership. Chrysler’s new mainstream family sedan was certainly a huge leap forward from its disappointing predecessor in the aesthetic department, but could it compete with the class leaders from Toyota, Honda, Nissan, Hyundai and Ford? The only way to find out was to drive one.

A surge in big truck sales triggered a drop in average fuel economy in September, but even these behemoths are getting a lot more efficient

A surge in big truck sales triggered a drop in average fuel economy in September, but even these behemoths are getting a lot more efficient?

The U.S. Environmental Protection Agency (EPA) has just published its 2014 fuel economy trends report, and though the news is generally positive, some potential storm clouds remain on the horizon f…


Audi Puts on Impressive Show With Autonomous RS7

However, it didn’t really prove anything other than that the basic technology for self-driving cars is now fairly well understood.  That doesn’t bring the full-function self-driving car any closer to regular use on open roads. That probably won’t happen until the end of the 2020s.

This demonstration was done on a closed course that is well mapped with no other vehicles around. The real issue that Audi and every other manufacturer has to deal with is working out all the kinks of dealing with weather, less than ideal road conditions, system robustness and of course programming ethics into the system.

That’s not something this particular group of engineers had to deal with. Not to take anything away from their achievement, but there is still a huge amount of work to do before we let self-driving cars loose.

There is no question that hybrid electric powertrains are more efficient than traditional internal combustion

There is no question that hybrid electric powertrains are more efficient than traditional internal combustion

However, if you still end up paying nearly $200,000 more over the life of the vehicle even after factoring in fuel savings, it becomes really hard to make a case for hybrid buses. Ann Arbor has been aggressive about acquiring hybrid buses over the past seven years with 52 of the 80 buses in the current fleet sporting motors and batteries. 

Unfortunately, most transit agencies struggle to cover costs from fares and as the AAATA prepares to expand services next year, it is rethinking whether to go hybrid or conventional diesel due to the expense. ?

The Ann Arbor Area Transportation Authority is known in part for its large fleet of hybrid buses, which burn through less fuel, generate fewer emissions and make slightly less noise than conventional diesel buses. But despite promises of a cleaner…


Well reasoned takedown of Elio Motors and their three-wheeled "wonder car"

Well reasoned takedown of Elio Motors and their three-wheeled "wonder car"

Back in the day, I was very skeptical of three-wheelers from Aptera and and Zap, neither of which ever made it to production.

From what I've seen, while Elio has managed to garner a lot of media attention, they are even less likely to ever get into customer hands.?

Elio Motors’ first car is gearing up to be the most drastic change in the industry since the invention of the cupholder. Here are the figures: 84 MPG, 5-star crash test rating, 3 wheels, 2 seats, and a reported price of $6,800. Sound too good to be true? Here are a few reasons why it might be.
