Compacts will have as much interior space as small cars; small cars as much as mid-size; mid-size as much as large. They don't have to all get fatter every year! Yay!

And our biggest problem, the large SUV, could be shrunk as well. It looks like they made a 7-seater out of a Murano. Thats good for fuel economy and handling when you don't have to buy an Urban Assault Vehicle just to get to soccer practice. ]]>Apr 30th 2008 11:15AMhttp://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/http://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/Apr 30th 2008 11:19AMhttp://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/http://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/

Its actually a fly-by-wire system borrowed from the Mitsubishi F-2. They discovered it was easier just to include retractable wings than to re-calibrate the system. ]]>Apr 30th 2008 11:47AMhttp://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/http://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/Apr 30th 2008 12:04PMhttp://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/http://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/Apr 30th 2008 12:22PMhttp://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/http://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/
I can only imagine the fun that ensues when the alternator on the car fails and the entire electrical system goes dead at once. No steering, throttle, brakes or shifter. What fun. Maybe the door releases will be electronic as well so you're really trapped! I'll pass, thank you. ]]>Apr 30th 2008 12:04PMhttp://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/http://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/Apr 30th 2008 12:21PMhttp://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/http://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/Apr 30th 2008 12:44PMhttp://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/http://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/
In case you folks did not notice, they fit seven seats into a long wheel base Murano here. I have an 03 Murano and there is no way I would want three rows in it. Way too cramped.]]>Apr 30th 2008 3:27PMhttp://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/http://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/
The problem is really one of failsafe positions. With throttle by wire, if the system detects a tremendous fault, they generally failsafe to some low throttle value, like 20% or so. You still have power to get off the road safely, but it is low enough that the brakes easily overpower the engine. Failure in the event of a lack of electricity is a non-issue because there won't be any ignition anyways.

Brake by wire can be done semi-safely. Again, make the failsafe position a low, but manageable brake value. Enough to stop the vehicle but not so high that the engine can't overpower it. But two troubles come up. Unlikely is a failure of throttle and brakes at the same time. What do you failsafe to then? Do you immediately stop? What if the vehicle is in a place where it is unsafe to stop? Failsafing to moving at 10mph isn't much better either. In the event of electrical system failure, I suppose the system could be made to default to some low braking value, but the fact remains that a conventional brake system requires TWO hydraulic lines to rupture before all braking is lost and if the brake system is intact it will work even without a battery in the car.

The big problem is steering. If the sensor in the column or the rack fails, what do you failsafe to? Straight ahead? Or does it veer slightly right? Even on straight roads, the driver rarely has the vehicle pointed EXACTLY straight (watch cars wander slightly left and right on the highway). Anywhere but the Oklahoma interstate and ANY fail"safe" position for steer by wire is going to be a BIG problem within 1/4 mile at the very best.

The final nail for me is that electrical systems often fail without warning. *poof*fizz* it's broken. To break the steering linkage either requires a BIG hit or a gradual loosening over time. Both of which give the driver warning that the system needs inspection. Same with brakes. You'll get a mushy pedal, squealing pads, etc. Lots of warning. (it's not my fault that many drivers miss these warnings!)

Sorry, no thanks. ]]>Apr 30th 2008 4:41PMhttp://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/http://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/Apr 30th 2008 1:01PMhttp://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/http://www.autoblog.com/2008/04/30/nissan-360-the-x-by-wire-ea2-concept/
Add all those back in and you're back at square 1.]]>Apr 30th 2008 2:48PM
