Mazda's next-gen SkyActiv engines will drop spark plugs in favor of high compression

Homogeneous charge compression ignition, or HCCI, is the black art of of internal combustion engines that aims to produce diesel-like fuel efficiency for the cost of gasoline. Although some of its competitors have developed and subsequently given up on the tech, Mazda confirmed that the next-generation of SkyActiv engines will employ HCCI technology, improving fuel economy by 30 percent and at the same time reducing exhaust emissions.

My last rear wheel drive car was an Infiniti J30.
I dreaded even a 1/4 inch of snow.
man was that car scary to drive, made my old Supra Turbo and Z-28 Camaro’s feel like Jeep 4x4’s in comparison..

Still, i wish i still owned any one of them cars, They were all beautiful vehicles....especially the 78 Z and the awesome Supra.

I drive a 2015 CX-5 it is a good vehicle

Apparently there was more FReepers around in 1862 that I ever would have guessed!

Oh the wasted potential in that 78 Z-28... 145 or 65 horse with a 4 barrel carb. My 70 1/2 RS was running close to 300 with a 2 barrel, headers and a bit of cam. My wife’s 2008 SKY redline is at that with a freakin 4 banger in it! :-)

The Army's old M-35 Deuce & a half and M-54 5-tons came with both multi-fuel and diesel-only engines.
In my experience the multi-fuels were not reliable and got replaced with diesel-only engines:

"One large use of a military multi-fuel engine was the LD series used in the US M35  2 1⁄2-ton and M54 5-ton trucks built between 1963 and 1970.
A military standard design using M.A.N. technology, it was able to use different fuels without preparation.[4][5]
Its primary fuel was Diesel #1, #2, or AP, but 70% to 90% of other fuels could be mixed with diesel, depending on how smooth the engine woud run.
Low octane commercial and aviation gasoline could be used if motor oil was added, jet fuel Jet A, B, JP-4, 5, 7, and 8 could be used, in an emergency fuel oil #1 and #2 could be used.[6]
In practice, they only used diesel fuel, their tactical advantage was never needed, and in time they were replaced with commercial diesel engines."

Dodge Charger

I want a practical sedan like a Camry with rear wheel drive as an option. I hear the automakers save $100 per car because it is easier to install the engine/drive train in a front wheel drive car. I would pay $100 bucks to have a RWD Camry.

The Dodge Charger SE is a V6 and a little more practical than the muscle versions, but I agree. It’s not like Toyota and Nissan don’t put RWD in their Lexus and Infiniti lines.

The untermensch never get a choice.

I wonder if an AWD car like a Ford Fusion would give a better feel than the understeer and torque steering of a front wheel drive.

I hate under steer too but apparently a lot of people like it or don’t know any better.
