Eurofighter Typhoon
A stock GMC Typhoon is governed by the ECU and will not exceed 124 MPH.
A typical Jumbo Jet will fly at 550-600 mph top speed.
The Eurofighter Typhoon at 1550mph top speed
The top speed of an A-10 is 440 mph.
The ef-2000 Eurofighter typhoon can travel at a top speed of up to 1321 m.ph at approx. 11,000m
Its top speed is more than 1600mph(mach2.4).
165 mph
The Eurofighter Typhoon has two Eurojet EJ2000 turbojets each producing 20,000lbs each. All this gives it a maximum speed of mach2 (about 1500 mph)An EF200 Eurofighter Typhoon can fly at 2,125 kmh, a speed of 1,321 mphThe Eurofighter has a top speed of about Mach 2 (twice the speed of sound), or 1,386 mph at 36,000 feet. It's major advantage over other fighters is its ability to 'supercruise', ie to maintain a speed of over mach 1 without using the engine afterburners thus saving fuel and dramatically improving it's fighting range and endurance.
depends on the jet, a Boeing 747-400 has a top speed of 614 mph at 35,000 feet
About 2500 km per hour.
