I'm not aware of any OEM system that uses DC motors so I suspect that your 10kw motor is really a permanent magnet synchronous AC motor. It's generally never a good idea to try to drive more than one motor with one controller - even more so if they are PMAC or PMDC since such motors are very sensitive to the input waveform. It needs to line up with the permanent magnets properly and you're unlikely to align them accurately enough while installing multiple motors together.
Motors can almost always handle more power than you'd expect but only for very short periods of time. But, permanent magnet motors can be damaged by trying to drive them too hard. They can be reasonably easy to damage. I think you're best served to get the proper motor for the job. But, sometimes the proper motor is expensive. So, I can see why it might be handy to try to piece things together. Another option you have is to try to find larger salvage motors. You can get 100kw systems out of scrapped OEM cars and bankruptcy auctions. You can probably extract decent sized motors out of wrecked hybrids. A salvaged drive system or motor along with its controller can be gotten for prices under $6000 - obviously depending on what you're getting. Don't expect to get a Tesla Model S drivetrain for $4000 or anything. ;) As for using the gauges, it can be a learning curve. I don't know of anyone off hand who has utilized the gauges in your car but a car that new almost certainly uses CAN for the communications. This is a communications standard and plenty of people (myself included) have experience with CAN and can assist with decoding the messages so you can use your existing gauges.
