Last week I had my five year old range rover in the shop and was given a new mid-range Jaguar as a loaner, which is considered a nice car. This post is not about the huge difference between the driving my P85D and the Jaguar, which somehow felt ponderous despite being over 1200 pounds lighter than the Tesla. This post is about two "features" the new Jaguar had (and I had not tested before) which also appear in new Range Rovers and other new ICE cars thanks to government fuel economy regulations. The first is engine stop-start when stopping at a light or stop sign. I suppose I could get used to it, but I find it really annoying. Stop-start can be defeated by pressing a button, but it has to be done each trip after taking it out of park. The second "feature" is the eight speed transmission, also tuned to meet fuel economy regulations. Accelerate to 60 and it shifts into such a high gear that the engine rumbles along just over idle. Lift your foot and there is no engine braking at all: the car continues to rumble along at pretty-much undiminished speed. I love the feel of engine braking, which is one of many reasons I love the Tesla, and which is one reason I've always chosen the largest engine when buying cars. When you floor the 8-speed Jaguar, it feels like it takes about five minutes to shift down the six gears needed to get going. Putting the transmission in sport mode doesn't seem to help very much. The point is that continuously tightening government fuel economy regulations are likely to continue to make the driving experience of pure ICE cars worse over time, relative to what Tesla already delivers. Soon, stepping on it will probably yield a turbo lag on a tiny engine. I suppose hybrid technology would help, if it is tuned for performance as in a P1 or new NSX, but the Tesla advantage will increase over time thanks to ICE Regulations, and I feel more bullish about the company's long-run prospects than before. As for my Rover, I now plan to keep it as long as I can rather than buy the new generation with stop-start, etc.
