Looks like the 911 will be the last man standing. Options

In the future Porsche line-up, the 911 will stand alone.

Very wise decision by Porsche to keep the 911 an ICE vehicle. It is the icon of the brand and will only get better and better. As long as the other sports car brands like Ferrari, Lamborghini, McClaren, etc make ICE vehicles so will Porsche need to stay in the game.

EVs are the future of automobiles. The electric motor drivetrain is so simple and efficient compared to an ICE drivetrain. Railroads have been using EVs for almost 100 years. Battery technology has gotten to a point where it is feasible for cars to carry enough batteries to make the battery EV practical.

It's interesting to think about the similarities between the diesel electric locomotive and EVs. The topology of both are nearly identical. Both get their electrical power from a driven alternator. The diesel drives its alternator with a diesel engine carrying both the alternator and diesel engine along with a tank of diesel fuel. The EV gets its power from alternators driven by coal/gas/oil/hydro/solar/wind/geo. Like the diesel, the EV carries its fuel with it stored for this generation of EVs in batteries.

Battery EVs are ok but have limitations on refueling. Charging overnight is great if you have a garage or off steet parking or charging stations at work. If not like many who live in apartments or even condos like I have with a large parking lot and no electricity close by, doing a refuel during the day for the better part of an hour isn't a step forward in progress. Hopefully the next generation of EVs will solve the long refuel issue with battery EVs.

Sadly, EVs are a regression to the early 1900s. Nothing new here.

There used to be electric railroads - they no longer exist for long haul freight use due to the lack of efficiency at which they operated vs a modern conventional rail system. Obviously I’m excluding Mag-Lev, local commuters, Subway, etc.

So - they aren’t the same topology at all. The diesel locomotive is more like a hybrid automobile. Power generation is on-board, uses fossil fuel to generate power which is then supplied to the electric motor for propulsion. Why is it that hybrid automobiles such as the Prius aren’t viewed as a legitimate step forward as an automotive option? Even a Prius can’t meet the new NHTSA mandates proposed for CAFE . . .

Hopefully the next generation of EVs will solve the long refuel issue with battery EVs.

Yup - I’ve personally been hearing that since 90’s and GM’s EV1 program. I’ll bet they were saying this in 1910 too.

Maybe we're talking about 2 different topologies. When I refer to an EV it is a vehicle which gets all its traction energy through wires to an electric motor like this picture. This diesel electric locomotive has the same topology as a battery EV with the addition of the battery being between the alternator and the motor thus being able to disconnect from the alternator providing the energy.

The diesel electric does have a disadvantage of not being able to store and reuse braking energy and needs those large ballast resistors and fans seen on the tops of locomotives.

Years ago, there was a brilliant ad campaign ahead of each episode of Top Gear UK, which had audio of someone breathing in and out while the video considered the amount of freight that could be moved on a single gallon of diesel via diesel-electric locomotives. It was extremely compelling.

Not sure if hybrid tech could be applied to trains, or if it would be meaningful given how efficient they already are (?), but I remember thinking it was a crime how much freight is moved by air or truck in North America (and, presumably, elsewhere).

Not to mention the fact that trucks don't mix well with cars at freeway speeds, and destroy roadways. But years later, legislation is still concentrating on light cars because cars bad. (IMG:style_emoticons/default/unsure.gif)
