One of the most obvious indicators of automotive engineering desire has always been to pursue extreme velocity. It forces designers, engineers and manufacturers into a space where there is no room for aerodynamic efficiency, power delivery, materials, cooling, stability or precision manufacturing to fail. Today, the race has become a very technical affair, and production cars are now getting to be as high-speed as experimental ones and land-speed record projects.

Electric propulsion is at the forefront of that change, and expectations of it are as much altered as those of advanced combustion engines were when they arrived. The all-electric Yangwang U9 Xtreme has become a prime example of the fact that battery-powered speed can hold up to the very highest standards. Meanwhile, iconic vehicles like the Bugatti Chiron Super Sport 300+ and SSC Tuatara maintain the reputation of the extraordinary performance of the internal-combustion engine. As a package, they represent the different approaches to achieving the same goal: to produce a vehicle with huge power output and that retains its stability and control at high speed.

Speed is also more than just an attribute of manufactured vehicles. Speed is measured in a variety of environments, as seen in jet-powered land vehicles, record-setting boats, military aircraft, high-speed data systems, scientific cameras, spacecraft, and even rapidly moving stars. These examples rely on various engineering principles, but they all have one thing in common: they are all examples of breaking physical constraints with ever more accurate technology. Whether it’s on the road or in the stratosphere, the quest for speed brings out the best in engineering.

1. Yangwang U9 Xtreme and the New Electric Speed Record 

The all-electric BYD’s luxury brand Yangwang U9 Xtreme is at the top of the range of production cars now on the market. Designed as a very low number of vehicles, only 30 were intended to be made, the hypercar has now been clocked to 308.34 mph (496.22 km/h) at the ATP Automotive Testing Papenburg facility in Germany. This makes the U9 Xtreme a step outside the realms of the extreme combustion-powered hypercar that have always been the norm.

Electric Power Meets Extreme Speed:

• Quad-Motor Electric Powertrain
• Direct-Drive Electric Transmission
• Ultra-Low Aerodynamic Drag
• Extreme High-Speed Stability
• Nürburgring Performance Capability

Numbers behind the U9 Xtreme are also astounding. Its electric powertrain consists of four motors which generate an astounding 3,027 hp (2,226 kW) provided by a direct-drive electric transmission. While electric motors are able to provide immediate torque, nearly 500 kmph calls for much more than just acceleration. The car also needs to control aerodynamic drag, tyres stresses, thermal load and boost high-speed stability.

The car’s 0.27 Cd drag coefficient is also very low, so it is also important to help it keep accelerating as aerodynamic resistance increases. The U9 Xtreme has also proven its abilities outside of a straight line speed test. Not all of its engineering is about a single figure, though, as it also recorded a lap time of 6:59.157 at the Nürburgring Nordschleife. The combination of huge electric power and aerodynamically good performance and vehicle control is a big step in the performance-car sector. The U9 Xtreme is a good example of the trend of electric propulsion moving from a technology for alternative performance to a real competitor at the highest level of automotive speed.

2. Bugatti Chiron Super Sport 300+ 

To be honest, the Bugatti Chiron Super Sport 300+ was one of the most significant milestones in the world of modern hypercars before the U9 Xtreme’s arrival. The machine, which was built in Bugatti’s factory in the French town of Molsheim, managed to hit 304.77 mph (490.48 km/h) during testing. That success proved the massive engineering work needed to keep a road-based vehicle steady and mechanically sound at speeds up to nearly 500 km per hour.

Breaking the 300-Mph Barrier: 

• 8.0-Litre Quad-Turbo W16
• 1,578-Horsepower Engine Output
• Seven-Speed Dual-Clutch Transmission
• Aerodynamic High-Speed Efficiency
• Record-Setting Production Performance

The heart of the Chiron Super Sport 300+ is a 1,578 hp (1,160 kW), W16 quad-turbo engine with over 1,180 lb-ft of torque. The hypercar is powered by a seven-speed dual clutch automatic transmission that launches the car from 0 to 100 km/h in about 2.4 seconds. The large power of its combustion engine compensates for its 0.35Cd drag coefficient, which is more than the U9 Xtreme (0.31Cd).

There is also a relationship between the record-setting prototype configuration and customer cars. The testing car has shown the immense capabilities of the Chiron platform but for customers, the car is still only electronically rated at 273 mph (440 km/h). The difference between the ability to prove what a car can do physically and the ability to produce a machine that can be used within practical and controlled limits. As such, the Chiron Super Sport 300+ is still a significant reminder of the achievements of old-school internal-combustion engineering, even as electric hypercars are increasingly setting new records.

3. SSC Tuatara and American High-Speed Engineering 

The SSC Tuatara is one of the largest designs in American engineering; it is developed by SSC North America, from Richland, Washington. On January 27, 2021, the Tuatara made its mark as one of the fastest production vehicles in the world with its two-way average speed of 282.9 mph (455.3 km/h) at Space Florida Launch and Landing Facility. This run was independently verified by Racelogic making it a more credible record in a run where even a slight measurement error can make all the difference.

American Hypercar Engineering:

• Twin-Turbocharged V8 Power
• Seven-Speed Automated Manual
• Streamlined Aerodynamic Body
• Verified Two-Way Speed Record
• Greater One-Way Speed Potential

The mechanical package of the Tuatara is based on a 5.9-litre twin-turbocharged V8 that delivers up to 1,750 hp (1,300 kW) and 984 lb-ft (1,350 Nm) of torque. It is powered by a seven-speed CIMA single-clutch automatic manual transmission, and the car’s sleek design helps to minimise drag at higher speeds. The Tuatara has a drag coefficient of 0.279 Cd, which means the shape will stay efficient at higher speeds, and the car goes from 0 to 100 km/h in around 2.7 seconds.

In later tests, the Tuatara has shown even more straight line potential. In May 2022, one was driven unidirectionally at a speed of 295 mph (475 km/h) in the same facility. One way run and a two way average are different means of measuring but the figure is a good indicator of the vehicle’s high speed performance. Next to it is the Yangwang U9 Track Edition, another example of China’s quick rise in the performance sector, with a nearly 3,000-hp quad-motor system and 1,200-volt electrical architecture that achieves 293.54 mph (472.41 km/h).

4. Precision Manufacturing Behind Extreme Performance 

Engines and motors aren’t the only drivers of record-setting numbers. All high performance vehicles require a wide range of manufacturing and testing support that can ensure a system will perform under extreme loads. All of these systems, such as cooling systems, braking systems, fuel delivery systems, electrical systems and pressure-sensitive connections, must work reliably. Even small parts failure can be a major engineering and safety issue at hypercar speeds.

Engineering Reliability at Extreme Speeds:

• Advanced Component Testing
• Pressure and Leak Testing
• Precision Sealing Connections
• Repeatable Manufacturing Verification
• High-Speed System Reliability

In the development and manufacturing of high performance vehicles therefore, testing equipment is critical. Specialized tools are used by manufacturers for pressure testing, leak detection, fluid transfer, system evacuation and connecting testing. Manufacturers can benefit from repeatable tests on systems designed to resist high operating pressures through the use of sealing connection equipment, including systems designed by FasTest, that are ISO 9001:2015 certified.

These processes are especially useful if components are required to be tested over the course of a production or development process. This precision is more evident with thousands of test cycles. Consistency is essential to high performance manufacturing: If a car is built to be as far out of the box as possible, and to operate at the limits of physics, then it can’t be tested once in a while and then be developed further as needed. Repeatable verification enables engineers to pinpoint spots where the components need improvement before they hit the road and helps confirm that parts perform as expected under controlled conditions. Under all of those record breaking times, there are actually more quiet accomplishments: a manufacturing process so accurate that it can create such extreme performance, time after time.

5. ThrustSSC and the Land-Speed Record Frontier 

There are times when the production-car constraints are eliminated and land vehicles are able to attain speeds that can make even the fastest hypercars look tame. ThrustSSC is one of the most well-known. The jet-powered machine was flown by Royal Air Force Wing Commander Andy Green who reached 763 mph (1,228 km/h) over one mile of flight in the Black Rock Desert on 15th October 1997. It was the first land vehicle to officially cross the sound barrier and one of the most remarkable achievements in the history of transportation.

Supersonic Land-Speed Engineering:

• Twin Rolls-Royce Spey Engines
• 102,000-Bhp Combined Output
• Supersonic Land-Speed Engineering
• Aerodynamic Stability Challenges
• Driver Safety and Protection

ThrustSSC used a pair of Spey turbofan engines, designed for military aircraft, by Rolls-Royce. The sum of their power was an astonishing 102,000 brake horsepower. The engineering challenge at such speeds is very different. The vehicle is no longer just a faster version of a road car; stability, surface conditions, propulsion, structural loads, and the way the car interacts with the speed of sound are all now a matter of prime importance.

The machine is a demonstration of how engineering for land speed can progress into a more aerospace-like discipline than traditional automotive design. The fast-paced experimentation has also generated moments when the resilience of humans entered the narrative. In 1966, drag racer Art Arfons was burned and bruised in a 610 mph crash at Bonneville Salt Flats that saw his jet-powered Green Monster survive. These are examples of the massive dangers inherent in the use of machines in otherwise conventional transportation. They also reinforce the importance of safety engineering, testing discipline and protection of the driver, as speed increases.

6. Spirit of Australia and the Pursuit of Speed on Water

Going for extreme velocity is not limited to land. On 8 October 1978, an Australian speedboat, designed and driven by Ken Warby, set an official world water speed record of 317 mph on the Tumut River. The ingenious design and build of the craft demonstrated that record-breaking performance can be achieved from the most unusual mix of materials, creativity and engineering, rather than traditional automotive engineering.

Breaking Speed Records on Water:

• Single Jet Engine Propulsion
• Aircraft Technology on Water
• High-Speed Water Stability
• Specialized Craft Engineering
• World Water-Speed Record

The jet engine was the only one on board the aircraft called Spirit of Australia: It was a Westinghouse J34 jet engine, which was originally used in aircraft. The conversion of jet propulsion to a watercraft posed completely different engineering problems. A boat moving at hundreds of miles per hour has to maintain stability while dealing with the constantly changing water surface and attitude changes can have profound effects.

However, it was not just the engine that was important to the record, the boat’s shape, weight distribution, control and interaction with the water was equally important. The Warby’s example is an example of how the concept of velocity varies with the environment. The resistance and stability issues of a vehicle moving at very high speeds over water are different from those seen for a car speeding over asphalt or a spacecraft in the near vacuum of space. But the engineering goal is always the same: achieve maximum propulsion with control. Spirit of Australia is still a testament to the ability of hard work engineering to turn a very special car into a record breaker.

7. V-22 Osprey and High-Speed Flight 

The shift from ground vehicles to aircraft adds an extra layer of engineering challenges. The Bell Boeing V-22 Osprey stands out from other aircraft not only for its ability to take off and land vertically, but also for its speed and range, which are similar to those of a turboprop plane. At 15,000 feet it can achieve speeds of about 351 mph, versus conventional helicopters, while still being able to fly from places where a runway isn’t required.

Balancing Speed With Flight Versatility:

• Twin Turboprop Engine System
• 6,150-Shaft-Horsepower Engines
• Tilting Engine Nacelles
• Vertical Takeoff Capability
• Speed and Mission Versatility

It is powered by two Rolls-Royce T406-AD-400 engines each generating around 6,150 shaft horsepower. The characteristic feature of the aircraft is its tilting engine nacelles that are capable of being turned in a forward flight position after lift-off. The new configuration provides for the transition of the Osprey from vertical to horizontal flight and gives it a level of versatility that is hard to match a conventional rotorcraft.

This gives a machine which is designed to be more flexible than a helicopter, but more capable than airplane. The Osprey is a testament to the fact that sometimes speed is just one component of an engineering goal. The design of the V-22 differs from that of a land speed record setting vehicle, which is designed for fast speeds and light weight, in that it must be fast, yet also carry a payload, have a range, be maneuverable, be able to lift itself off the ground, and be reliable in operation. The design gives an idea about the performance of engineering depends on the mission of a machine for which it is made. While velocity is important, it can be even more important to be able to do more than just run fast.

8. BrahMos and Supersonic Technological Velocity 

The other type of ultra-fast speed can be found in the advanced aerospace systems like the BrahMos cruise missile, which is one of the world’s fastest supersonic cruise missiles. It can achieve a Mach number of around 3.5 and is powered by a ramjet propulsion system in order to maintain supersonic flight. Its engineering considerations focus on high speed flight, small propulsion, guidance and operational flexibility, rather than on transportation of passengers or recreational use.

Engineering Sustained Supersonic Velocity:

• Ramjet-Based Supersonic Propulsion
• Mach 3.5 Maximum Speed
• Multi-Platform Deployment Capability
• Advanced Aerodynamic Control
• Sustained High-Speed Performance

The BrahMos system can be launched by various platforms, such as aircraft, ships, submarines, and mobile platforms. This versatility shows the high-speed engineering can be incorporated into various operational environments without having to use a particular configuration of vehicle. To sustain supersonic flight requires propulsion and aerodynamic systems that can withstand the harsh conditions of flight, and the vehicle must be controllable at speeds far greater than those of normal aircraft.

This is, of course, unlike a hypercar or land-speed car in the big scheme of things. In an aerospace system, the architecture can be dedicated to providing a high speed capability, whereas, in a production car, it is necessary to provide a high speed capability together with the other functions that it needs to perform on a day-to-day basis. These technologies illustrate that “fast” can mean very different when solving an engineering problem.

9. The Speed of Data, Computation and Observation

In modern engineering, there are also other ways to measure speed, which are not associated with the movement of things. El Capitan, the supercomputer at Lawrence Livermore National Laboratory, has hit a new high with its peak performance of 2.821 exaFLOPS (exaFLOPS equals quintillions of floating-point operations per second). It’s built using AMD Instinct MI300A accelerated processing units, which feature Zen 4 CPU cores along with GPU chiplets. Here, speed is defined in terms of the number of calculations that a system can execute, and not in terms of the distance a physical object can cover.

Measuring Speed Beyond Physical Motion:

• El Capitan Supercomputing Performance
• AMD Accelerated Processing Architecture
• Petabit Optical Data Transmission
• Long-Distance Fiber Communication
• Ultra-Fast Scientific Imaging

Communication technology has broken another barrier. The scientists at Japan’s National Institute of Information and Communications Technology were able to transmit data at a record-breaking speed of 1.02 petabits per second, using a 19-core optical-fiber cable, which was stretched 1,808 kilometers. This is a good example of the potential of designing fibers and transmission methods to carry a vast amount of information over the same physical plant.

The great rate of observation is needed for the science. The Canada’s SCARF camera system can capture image data at an incredible speed of about 156.3 trillion frames per second, which allows researchers to see transient events, which are events that last over such a short time. From these technologies, it is possible to see that engineering velocity does not always mean increase the speed of an object. It can involve an increase in information being processed, a faster transfer of data, or capturing physical events before they are lost.

10. Parker Solar Probe, Hypervelocity Stars, and the Ultimate Limit 

The highest speeds of man-made technology seem to come when spacecraft leave the atmosphere of the planet Earth. The fastest man-made speed recorded by NASA’s Parker Solar Probe in its journey to the Sun’s outer corona was about 150 kilometers per second. At later phases of its life, it will travel at speeds of up to 190 km/s, or about 0.064 percent of the speed of light. Its success illustrates the power of gravitational dynamics and a well-designed spacecraft to generate velocities far greater than those attainable on Earth by any automobile, airplane, or spacecraft.

Pushing the Ultimate Limits of Speed:

• Parker Solar Probe Velocity
• Gravity-Assisted Spacecraft Acceleration
• Hypervelocity Stellar Motion
• Sagittarius A* Gravitational Influence
• Fundamental Speed of Light Limit

But nature works on a much bigger scale. The star S4714 orbits the supermassive black hole Sagittarius A* in the Milky Way at about 15,000 miles per second (8 percent of the speed of light). It is about a 12-year orbit and the high velocity is associated with the huge gravity around the black hole. In such extraordinary motion, a natural example of velocity is created, not by an engine, but rather by gravity operating in an extraordinary way.

The theoretical edge of physics is the hypothetical tachyon, a particle that could have a speed greater than that of light (c) and, by definition, behave differently than ordinary matter. There is no experimental evidence for the existence of tachyons, and in modern relativity, light is the ultimate speed limit at which objects can move in a vacuum (299,792,458 m/s in a vacuum). The quest for speed continues with electric hypercars, jet-powered land vehicles, spacecraft, optical networks, supercomputers, and hypervelocity stars; the realm of engineering and physics is truly amazing. It’s a race to speed and a much wider investigation of the limits of technology and nature.
