Aircraft
I was the First Officer and Pilot Flying on Aircraft X from ZZZ-ZZZ1. The aircraft was leaving a maintenance facility and heading back to resume normal line flying. After both the Captain and I conducted thorough preflight; we started the jet and began to taxi to Runway XX. The taxi was uneventful. The takeoff roll began at approximately XA:15 pm and yielded nothing out of the ordinary till a few knots below V1. Approaching V1 I began to smell a very pungent order and shortly after began to see a haze like smoke forming in the cockpit. I called 'reject; reject; reject' to which the Captain and I performed the Rejected Takeoff procedure. We taxied off the runway and had airport operations follow us back to the maintenance facility. The taxi back to the maintenance facility yielded no additional smoke or fumes.
EMB-135LR First Officer reported pungent odor and haze occurred during takeoff roll. Crew executed a rejected takeoff and return to maintenance.
