1 minute = 60 seconds
2 minutes =120 seconds
(24.6 meters/sec) / (120 sec) = 0.205 meter/sec² = about 0.021 of a 'G'.
The mass of the car is irrelevant, in order to go just this far.
If you want to go a little farther, you can calculate the average force on the car, since you do know its mass.
Force = (mass) x (acceleration) = (1,000 kg) x (0.205m/s²) = 205 newtons
That's about 46 pounds of force accelerating the car . . . not a very powerful engine for a car that weighs more than a ton.
