Jenson Button is expecting the 2014 cars to be more difficult to drive due to increased torque and less downforce – a prospect that he does not find exciting.

The new engines will be fitted with fuel flow restrictors and lower rev limiters, but will still produce a similar level of power when combined with the energy recovery boost systems. However, they will also produce significantly more torque, which is set to increase the chances of wheelspin at low revs and make the cars more of a handful.
