I did some numbers on this one time and to get a 3000 lb vehicle airborne in VTOL requires about 1000-1500 HP and 2000 HP to really be safe. 2000 HP is about the point where you get a 2:1 TWR and get more drone like behavior including fast stops and redundancy. It also takes a ton of fuel to power 2000 HP worth of engine(s), so realistically this 3000 lb 1400 KG car would need wings or something to get good fuel economy.
In order to power these beasts, especially within the weight requires turbine engines which are expensive. Somewhere around 100k on the lower end. Two 1200 HP jet turbines would be good but would probably cost around 150-200k in America anyways. 2000 HP is also going to use close to a gallon per minute of fuel. So take offs and landings outside of runways would be a bit costly.
You would also need autopilot features in controlled airspace or people would be crashing into buildings and stuff within cities.
It's a cool idea but there are many practical reasons why flying cars won't really work rn. The technology exists but it's expensive and hard to maintain and dangerous and also can be very loud.
3000 lb is very optimistic for a passenger vehicle, even a car. Most cars are not 3000 lbs. Only the smallest ones are. It's probably possible by using carbon fiber and plastic and composite components.
The real issue is cost. Right now a decent car like a flying vehicle that can carry 2 or 4 people is going to cost around 500k without big markups. The twin engines alone are going to be pushing north of 200k. If you go with batteries you can do it much cheaper but you are limited to 1-3 hours of flight time per day.
If you go much smaller like a 600-700 lb drone bike thing. You could probably get away with 400 HP inline 4 cylinder which is not easy but it's doable, but it's dangerous because you don't have redundancy. With a twin engine drone you can lose an engine and still land and recover from anything. Parachutes only work when you have a bit of time.
