Do you think the tech in cars will shift more so to the engines? If it does I could see a lot going wrong, but it is honestly inevitable. I just do not see sport cars getting a speed boost from technology, but I know it is possible.
It already has. We have drive-by-wire systems, driving assistance technologies that can tap into the engine management systems to assist in collision prevention. The engine management systems benefit from newer developments for faster reading/monitoring (ie sports cars) or enable technologies such as cylinder deactivation or start/stop technology. All of those rely majorly on a vehicle's electronics system.
I mean look at the Nissan GT-R, its a marvelous performance machine only made possible with technology. The vehicle ECU monitors every aspect of the vehicle and alters everything accordingly. You also see vehicles have adaptive suspension technologies that can adapt to road conditions, which is tech-based.
I can go on and on about all the tech systems but I hope you get the idea of why we're trying to cover it all.
I do see tech improving fuel economy of vehicles. There's only so much you can do mechanically but with the aid of new electronics and even electric motors, we will see new improvements in the future. Mazda has their i-eLoop that captures wasted energy from braking and stores it into a capacitor to run vehicle accessories at idle, which is made possible by technological developents. It also yields about a 1-2mpg increase on a pure gasoline vehicle too.
Have you seen any of the new Infinity's tech in their vehicles? I have heard a lot of things that are good about them. I drive a 2002 M45 and it was one of the best cars I have ever owned when it comes to tech. I absolutely love how they put their cars together.
