I rented a car from Enterprise Rent-a-Car for a job interview that I had on October 31st, 2013.
I ended up getting a 2014 Jeep Grand Cherokee with the diesel engine, the same diesel engine as the 2014 Dodge Ram 1500. This vehicle has a push button start, and a safety feature is that you cannot start the engine without pressing the brake pedal and being in "P." It tells you right on the dashboard. The fuel tank cap cover is also push button.
The far left of the steering wheel with an "OK" button and arrow keys lets you scroll through five different menu items that are displayed on the far left of the dashboard. One is fuel economy and range, which I used on this trip. You can adjust the speedometer between kilometers per hour and miles per hour, you can adjust to the radio station that you want.
Another feature is ParkSense. I parked the vehicle the instant after the ParkSense started to beep, and the rear bumper was approximately ten feet from the front bumper of another car. So the ParkSense activates when you are ten feet away from another vehicle (towards the back). There is a rear view camera for when you back out of a parking space for your convenience.
For those of you that enjoy four-wheel drive, there is a center control in the console that lets you adjust the terrain, whether it be snow, sand, mud or rock. It is a push button to activate Low 4WD.
I thought this vehicle had good suspension when I was going over some speed bumps, it was not too flexible or rigid. The vehicle performed very well on I-80 while I was going to my job interview. The cruise control is on the right of the steering wheel, it has the "Set +" and "Set -" keys with the cruise control switch in the middle.
After my interview, I decided to test the vehicle by returning back to Reno on highways 89, 28 and 431. The curves that post recommended speeds, I was able to drive most of them 10 mph over the recommended speeds with no problems.
My average fuel economy for the entire trip ended up being 18.4 miles per gallon. I did not realize until near the end of my trip that the air conditioning was on the whole time, so the 18.4 mpg that I obtained could have been more like 19.0 or more. I do not remember if I had a gas or diesel motor in this vehicle, and I did have the "Eco mode" on the whole trip.
The push button must be the future of vehicles. Other than my having the push button start for the first time, I was impressed with this vehicle. I drove it without towing a trailer or having a big load of cargo, and I did not drive it on other road surfaces besides concrete and asphalt.
Feel free to check out Jeep's website, they have a lot of good pictures available.
