In theory more gears will provide both performance and fuel economy benefits if the transmission is tuned properly. This is due to it allowing the engine operate in a narrower RPM band for either power or fuel efficiency. For fuel efficiency it can also allow a taller final gear for cruising while still keeping…

It's a combination of texting while walking and texting while driving. My wife saw a person texting while walking up to a crosswalk and then proceed to step out in front of traffic without looking up. Needless to say he made it out ok, but he pissed off a lot of drivers who had to slam their brakes.

I think the high beltlines and smaller windows are more of a result of rollover and pedestrian protection laws.

Seeing a Mercedes with that body molding and wing just make me think of this.

Hydrogen is easily produced from electricity. I have always been in the school of thought that a hydrogen distribution system would NOT be the same as the current gasoline model. Hydrogen could be produced at home. And while there wouldn’t be as many as there are today, fueling stations could also produced their own.…

The same can be said of Nintendo today.

I used it a lot on my Ford Explorer. It liked to stall while coasting, and I shift it to neutral to restart it while still coasting. My brother's Explorer (with a different engine than mine) would do the same thing.

I haven't heard of any reports of the new Z06 motors blowing up or anything. What sources do you have that say they are unreliable? I am just curious more than anything?

Emissions, durability, and driveability.

This has the potential to go well beyond, "parts that obviously circumvent emissions controls and are meant for street cars (think “coal rolling” tunes for bro-trucks)." At the end of the day, ALL engine modifications have the potential to change the emissions profile of a car. Intake, exhaust, headers, cams, turbos,…

If you are going to talk about watering down the brand then you shouldn't leave out MB and BMW. It's amazing how many S500's and 5-series I see driving around in the not so good parts of town.

GM is slowing down fleet sales. It will affect them in multiple ways. Yes, fleet sales are good at maintaining volume and keeping plants running at capacity. However, fleet sales are generally sold at lower margins, strike 1. Secondly, as has already been mentioned, fleet sales flood the lightly used car market after…

I am amazed at how many Cavaliers I still see on the road on a regular basis.

Bonus points for the pinkish stripe.

They looked very similar to my ZL1 wheels as well, including the nameplate engraved on the inner lip. I really like this 10 spoke design and how GM has kept it fresh on several different models.

I looked down in the comments to see if anyone had already posted this. The 2013 427 Anniversary edition was essentially a C6 Z06 in convertible form.

Up to a point. If you get too much bore then you start losing out to how fast the flame front travels. Too much stroke and your piston speed gets too high.

Good point, and I am unsure about a manual in a CTS. I know the V is 8-speed Auto only.

The SS was basically built to fill production capacity in Australia. It was never intended to be a high volume seller.

It's called a CTS.
