Create descendant class based on Eloquent model

Let's say I have Vehicle model (it's Eloquent model) that stores different types of vehicles (in vehicles table). Of course, there are many different types of vehicles, so I have for example:

class Car extends Vehicle {
}

class Bicycle extends Vehicle {
}

and so on.

now I need to find object based on vehicle and here's the problem. I've added the following method in Vehicle model:

public function getClass()
{
    return __NAMESPACE__ . '\\' . ucfirst($this->type)
}

so I can find the class name I should use.

But the only way to get valid class is like this:

$vehicle = Vehicle::findOrFail($vehicleId);
$vehicle = ($vehicle->getClass())::find($vehicleId);

which is not the best solution because I need to run 2 exact same queries to get valid final class.

Is there any way to achieve same without duplicating the query?
