  1. Saw this on Facebook. And yes, I’ll take it in black please.

  2. I don't think it really matters as to the reason. Just about all automakers are dialing up caution; quarter after quarter after quarter have only show incremental growth, so it's logical from a business case. - - - - - Meanwhile, here's a spy shot of an S-class with mid-cycle autonomous 'upgrades' : Looks great- very classy!

  3. Do you know what Corolla and Camry sell Because those names have been around for 50 year, people know what they are like Pepsi and Coca-Cola. No one will know what a K5 is or what brand even sells it.

  4. Let me put it in a simple way for everyone to understand. The problem with electric cars is that the energy density of batteries is horrible. A battery that gets you 300 miles is over 1000 lbs -- closer to 2000 if you count the structure you need around it not just the cells. 10 gallons of gasoline takes you 300 miles in a 30 mpg car and it weighs 60 pounds (the tank weighs less than the fuel) The way to solve the problem is to make the battery as small as possible and use it as a buffer rather than an energy source. You then replenish it with the smallest and lightest device that can convert hydrocarbon fuel to electric charge. Now picture a turbocharger a small car like the CLA45 AMG. That'll flow enough air to make about 400hp and raise the pressure about 3:1. If you take two of those you can raise the pressure about 9:1 and make 400hp without the pistons. If you only need 40 hp, imagine the turbos being 1/10th the size of the CLA45 turbo. Think two little pill bottles!

  5. The solution is simple. A SMALL BATTERY of about 10-20 kWh (30-60 mile range) capable of high current draws. A micro gas turbine generator making about 30 kW (40 hp) capabe of recharging the battery in 20-40 mins with the car stationary or about twice that when it is cruising along gently on the freeway. Who cares if the turbine is fuel efficient? It is only used when you are on a long trip or to "recover" from a stint of very aggressive driving. The important thing is that the turbine is very small, does not need coolant and is essentially maintenance free between time to overhaul. It'll fit in the spare tire well! The simplest practical design is a 2-stage centrifugal unit that looks like two sequential turbos with a combustor can between the compressor and the turbine, as well as a high speed AC generator on the shaft of the low pressure compressor. It should cost about as much as two turbos and an electric motor. Two centrifugal stages is good for about compressor pressure ratio 10:1~12:1 compression ratio (3.3 x 3.3 to 4 x 4) -- about the same as a modern piston engine. It is no GEnx, but it's good enough. This also ensures that emissions will be about the same as a typical gasoline piston engine. Unlike a Hybrid's ICE, the turbine either operates at optimal speed or not at all. When starting the generator-motor spins the low pressure compressor to about 150,000 rpm and generates a combustor inlet pressure ratio of about 3~4:1 which should be enough for the unit to be self sustaining. Fuel combustion and will spin up the high pressure turbine to speed and bring it to the operating pressure ratio. Start up should take about a minute. The Driver as a three position switch for the turbine generator -- OFF, ON or AUTO. OFF is pure electric. ON runs the turbine as long as the battery is not full. Auto runs the turbine when the battery drops below 20% (6~12 mile range). Very simple.

  6. so has Chevy Blazer!!!!! now admittedly, what a Blazer is, is slightly different now.

  7. I forgot the K900 was sold in the US...Kia has a lot of sedans in the US...

  8. And? It’s production (which had literally just started) was delayed as a result of the strike, same as building a one off concept for CES was delayed. What is your EV hating mind not getting here? Again, offer proof of your claim and maybe it doesn’t come off as the normal EV trolling nonsense you normally spew.

  9. You just chose EV over your wife and children. Interesting insight. Stunned.

  10. I could see the next gen versions of the 3 current smaller Jeeps on such a platform. Maybe a Dodge Journey replacement also. It will be interesting to see if any sedans come to the US and under what brands, given the current US sedan market contraction...I do like the looks of the 508.

  11. I asked my North Korean friend how it was there, he said he couldn't complain On a scale of North Korea to America, how free are you tonight? Talking to a liberal is like trying to explain social media to a 70 years old. A liberal is just a conservative that hasn't been mugged yet. I don't approve of political jokes...I've seen too many of them get elected.

  12. Actually, it does. Not a heck of a lot, but noticeably more than very low boost Germans like he Audi 4.0T. The reason is simple. It takes longer to get to 640 lb-ft than it does to 444 lb-ft. That boost rise simply takes longer. The Germans have very tiny turbos reaching only 122 lb-ft per liter vs 152. Boost only reaches 9.5 psi and plateaus from 1,500 to 5,100 rpm. Anyway, the whole hand built and exclusive to Cadillac thing is bullcrap. You can handbuilt and make exclusive a version of the small block V8 too.

  14. Just not a fan of the Escape any more. If I wanted a Mazda, I would buy one. Now the Bronco Scout, on the other hand......

  15. No doubt the sound of a connecting rod blowing thru the oil pain is distinctive, too.

  16. Yes, I am very much an Evolutionist, if wife, kids, parents, etc. did not pay attention to their job of walking and watching out, they get what they get. SAD YES!, Government is NOT supposed to protect you from Stupidity!
