The tank is the only working example in existence and can be seen bombing around Bovington Tank Museum in Dorset.
It has recently been fitted with a genuine German wartime Maybach engine and its fan drives have been re-engineered from original blueprints.
Now it boasts an original inertia starter handle that needs to be wound furiously to coax into life the massive monster that terrified the Allies in the war.
It is the end of a two-year, £80,000 restoration project to return Tiger Tank 131 to its original war time specification.
But efforts to restore the tank by museum experts have been on-going on since the 1990s when the museum received a grant of 100,000 pounds.
The tank is not fuel efficient however, and does about three gallons to the mile.
And despite the efforts of restoring it, staff at Bovington have been struggling to buy enough fuel because of the panic buying across the county.
The 55 ton tank was a fearsome and frightening weapon and totally superior to anything the British had during the war.
Rounds from Allied tanks could not penetrate its 100mm thick armour and the tank soon gained legendary status after its introduction in 1942.
Tiger Tank 131 was captured after a lucky hit by a British Churchill tank, belonging to 48 Royal Tank Regiment, in the Tunisian desert in April, 1943.
The shot glanced off its powerful 88mm cannon and wedged in the turret ring, rendering it useless.
The five man German crew abandoned the Tiger which was captured by the Allies intact and virtually unscathed.
Winston Churchill, who was in Tunisia at the time, gave it a personal inspection and clambered all over it.
It was then sent straight back to Britain for detailed examination so the Allies could look for any weaknesses. The King, George VI, also went to inspect it.
It was moved to Bovington in 1951, complete with the small dent in the turret where it had been hit years before.
Although museum staff have had it moving before, the engine was not right and it kept breaking down.
But now it should be far more reliable with its V12 engine and having been returned to its wartime specification.
David Willey, museum curator at Bovington, said: "The Tiger tank is a vehicle with an almost mythical status which far outweighed its actual impact on the battlefield.
"It represented a significant leap forward in tank design and outmatched anything that the Allies could field at the time.
"With its powerful 88mm gun and thick armour, Allied tank crews genuinely feared an encounter with a Tiger tank - and it is this mighty reputation that has given rise to such fascination in this particular vehicle.
"It is the most complete and best preserved example, and the only one in running order.
"It is the most iconic tank of the Second World War and continues to capture the imagination of audiences in to the 21st Century.
"If you think you've got trouble getting hold of petrol at the moment, it's worth noting that to fill the Tiger's tanks would take 534 litres.
"That's 27 Jerry cans. At today's prices, that would cost around 740 pounds and you would only get around three gallons per mile off road.
"The Jerry can is so called because the British Forces preferred the German method of supplying fuel in re-usable, sealable tin cans.
"Before this, up to a third of our fuel was being lost in our equivalent, the "flimsy" - a big square tin that was used once and thrown away.
"So we pinched the design and the name "Jerry Can" stuck.
"On top of that, this Tiger was captured in North Africa where all German petrol supplies had to be shipped across the Mediterranean.
"We know that only a quarter of their supplies were getting through due to the activity of the Royal Navy and the Royal Air Force.
"As a result of this, the German Army had to be frugal with the supplies of petrol they did have."
