Alan Abbott, 49, attacked his ex-partner at a house in Arbury, Cambridge, at about 5am on Friday, 13 October.
He threw her into his bedroom, hit her about 30 times for about 20 minutes until the victim called Abbott’s sister for help.
Abbott continued to hit her in the head, this time with her mobile phone, with the victim fearing she was going to die.
He had told her he was going to kill her and would not be bothered if he went to prison.
The sister intervened and the victim ran from the house barefooted, leaving her car keys on a table inside the house, and began knocking on neighbour’s doors asking for help.
Abbott followed her so she hid behind a fence until she heard him walk away.
Officers arrived at about 6.30am and were met by the victim covered in blood who also told them Abbott had taken her car and was revving the engine.
He drove the car from a neighbouring street, reversed and intentionally rammed the police car which was parked next to the officers who were speaking to the victim.
Abbott then reversed the car into a tree before getting out and went straight towards the officers, one of whom used her PAVA spray on him, and they attempted to restrain and arrest him.
During the struggle, Abbott pulled both officers’ hair and threw them to the ground.
One officer suffered soft tissue damage to her back while her colleague was left with scratches to her face, arm and hand with her police radio and watch damaged.
An off-duty detective driving to work assisted the officers to get Abbott under control and arrested.
When being driven to custody, Abbott spat inside the cage of the police van and repeatedly said the officers “deserved it.”
The victim was taken to hospital suffering from cuts.
On Wednesday (6 December), at Cambridge Crown Court, Abbott, of Hering Road, Trumpington, Cambridge, was jailed for three years and four months having pleaded guilty to actual bodily harm, aggravated vehicle taking and property damage under £5,000, dangerous driving, driving with no licence, driving with no insurance and two counts of assault by beating of an emergency worker.
He also pleaded guilty to three counts of criminal damage to property valued under £5,000 and received no separate penalty.
Abbott was also disqualified from driving for four years and six months and will have to re-test.
He will also be subject to a seven-year restraining order.
