There are basically two classes of fixed-wing aircraft: those where the controls are physically connected to the flight surfaces, and those that are controlled entirely by hydraulic pressure and/or electronics. The latter is increasingly common in large airliners, but has been around for decades (a DC-10 was infamously controllable only by the wing-engine throttles after the tail engine shattered and took all the hydraulics with it - roughly half the people on board survived the "landing").
Both of them are easily capable of landing after all engines fail at cruising altitude. Electric power, where necessary, is generated by a small windmill which extends from the body of the plane when needed.
Only the directly-connected type - which (conservatively) includes pretty much anything up to about corporate-jet size or built before 1970 - will be able to continue flying in a controlled fashion if the electronics are destroyed by a large EMP. Some of the hydraulic indirect types will probably fly too, depending on how independent the controls are of EMP-sensitive electronics and whether a source of hydraulic pressure remains. You do *not* want to be on board *any* Airbus if an EMP goes off within range - they are entirely computer-controlled, and the pilot's joystick inputs are merely suggestions.
Whether the navigation equipment will still work is, frankly, unlikely. The pilot will have to find his way to an airport the hard way.
Going back to the original subject, all cars certified for road use have a physical link for steering (usually with power assistance these days, but this does nothing at highway speeds), and two braking systems that can be applied by human effort alone (both hand and foot brakes, though the footbrake is usually power-assisted too). That's enough to easily retain control in the face of total electrical failure and engine cutout.
But it is worth noting that a lot of old cars have engines, with carburettors and distributors, that would not be affected by any kind of EMP. At worst, it would induce a momentary misfire and fry the radio. If you look in the right scrapyards, you can find Renault and Volvo engines that have outlived their vehicles and are robust enough to withstand quite a lot of boring and boosting... so serious criminals who put some thought and effort into preparing their crime can avoid being stopped by the EMP and still have a fast enough car to keep ahead of the chase. But high-speed chases are usually the result of insufficient planning anyway...
