Ford introduced the newly redesigned Mustang (code-named SN-95) in December 1993.  It was the first major redesign since the third-generation Fox-bodied Mustang that was introduced for the 1979 model year. Known as Fox-4 (because it was based on the Fox platform as a 1994 model), the new 1994 Mustang was an improvement over the outgoing 1993 model.  The new car's ride, handling, styling, ergonomics, and standard and optional equipment were improved from the previous model. However, the Chevrolet Camaro Z/28 and Pontiac Firebird Formula and Trans Am, that were redesigned for 1993, came standard with 275 hp (205 kW),  while the 1994 Mustang GT engine produced 215 hp (160 kW)

The 1994 Cobra was introduced midway through the model year with the same engine as the 1993 Cobra. With its GT-40 cast-iron heads and lower intake and its Cobra-specific upper intake, power increased to 240 hp (179 kW; 243 PS).  However, the actual output of the Cobra's GT-40 enhanced engine was probably higher.  Ford claimed 6.3 seconds to achieve 60 mph and a top speed of 140 mph (225 km/h). Muscle Mustangs & Fast Fords magazine tested a 1994 Cobra coupe and achieved a 0-60 mph acceleration time of 5.7 seconds and the quarter mile in 13.87 seconds at 99.49 mph (160.11 km/h).

Initially, the 1994 SVT Cobra was only available as a coupe, but the first factory-produced SVT Cobra convertible was the 1994 Indy 500 Pace Car Replica. On the same day that the new 1994 Cobra coupe was launched, SVT announced that it would be building a Cobra convertible (the first factory-produced "Cobra" convertible since the 1970 Shelby models) and that this convertible had been selected to pace the 1994 Indianapolis 500. The new Cobra convertible, or Indy 500 Pace Car Replica, was made available later in the 1994 model year.

The Bugatti WR16 is a quad-turbocharged, W16 engine, manufactured under the high-performance luxury sports car marque Bugatti, since 2005.

Volkswagen is a shareholder of Bugatti stock and shares in the profits of Bugatti products as of 2024.

In 2021, Bugatti announced the retirement of the W16 engine, making the Bugatti Chiron Super Sport L'Ultime, which ended production in May 2024, the final automobile to use the engine.

The W16 engine that Volkswagen Group uses in its Bugatti Veyron and Chiron has a displacement of 8.0 L (488 cu in) and four turbochargers. It is effectively two narrow-angle VR8 engines (based on the VR6 design) mated at an included angle of 90 degrees on a common crankshaft.

The most powerful version of this engine, installed in the Bugatti Bolide, generates 1,361 kW (1,825 hp; 1,850 PS) at 7,000 rpm, and 1,364 lb⋅ft (1,849 N⋅m).

Variable Valve Timing & Lift Electronic Control (VTEC) is a system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine, resulting in higher performance at high RPM, and lower fuel consumption at low RPM. The VTEC system uses two (or occasionally three) camshaft profiles and hydraulically selects between profiles. It was invented by Honda engineer Ikuo Kajitani. It is distinctly different from standard VVT (variable valve timing) systems which change only the valve timings and do not change the camshaft profile or valve lift in any way.

Japan levies a tax based on engine displacement, and Japanese auto manufacturers have correspondingly focused their research and development efforts toward improving the performance of their smaller engine designs. One method for increasing performance into a static displacement includes forced induction, as with models such as the Toyota Supra and Nissan 300ZX, which used turbocharger applications, and the Toyota MR2, which used a supercharger for some model years. Another approach is the rotary engine used in the Mazda RX-7 and RX-8. A third option is to change the cam timing profile, of which Honda’s VTEC system was the first production engine to use cam‑switching technology to vary both valve timing and lift.

The VTEC system provides the engine with valve timing optimized for both low- and high-RPM operations. In basic form, the single cam lobe and follower/rocker arm of a conventional engine is replaced with a locking multi-part rocker arm and two cam profiles: one optimized for low-RPM stability and fuel efficiency, and the other designed to maximize high-RPM power output. The switching operation between the two cam lobes is controlled by the ECU, which takes account of engine oil pressure, engine temperature, vehicle speed, engine speed, and throttle position. Using these inputs, the ECU is programmed to switch from the low-lift to the high-lift cam lobes when certain conditions are met. At the switch point, a solenoid is actuated that allows oil pressure from a spool valve to operate a locking pin, which binds the high-RPM rocker arm to the low-RPM ones. From this point on, the valves open and close according to the high-lift profile, which opens the valve further and for a longer time. The switch-over point is variable, between a minimum and maximum point, and is determined by engine load. The switch-down back from high- to low-RPM cams is set to occur at a lower engine speed than the switch-up (representing a hysteretic cycle) to avoid a situation in which the engine is asked to operate continuously at or around the switch-over point.

The older approach to timing adjustments is to produce a camshaft with a valve timing profile that is better suited to low-RPM operation. The improvements in low-RPM performance, which is where most street-driven automobiles operate a majority of the time, occur in trade for a power and efficiency loss at higher-RPM ranges. Correspondingly, VTEC attempts to combine low-RPM fuel efficiency and stability with high-RPM performance.

A nuclear weapon[a] is an explosive device that derives its destructive force from nuclear reactions, either nuclear fission (fission or atomic bomb) or a combination of fission and nuclear fusion reactions (thermonuclear weapon), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter.



Nuclear weapons have had yields between 10 tons (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). Yields in the low kilotons can devastate cities. A thermonuclear weapon weighing as little as 600 pounds (270 kg) can release energy equal to more than 1.2 megatons of TNT (5.0 PJ).[1] Apart from the blast, effects of nuclear weapons include extreme heat and ionizing radiation, firestorms, radioactive nuclear fallout, an electromagnetic pulse, and a radar blackout.

The first nuclear weapons were developed by the United States in collaboration with the United Kingdom and Canada during World War II in the Manhattan Project. Production requires a large scientific and industrial complex, primarily for the production of fissile material, either from nuclear reactors with reprocessing plants or from uranium enrichment facilities. Nuclear weapons have been used twice in war, in the 1945 atomic bombings of Hiroshima and Nagasaki that killed between 150,000 and 246,000 people. Nuclear deterrence, including mutually assured destruction, aims to prevent nuclear warfare via the threat of unacceptable damage and the danger of escalation to nuclear holocaust. A nuclear arms race for weapons and their delivery systems was a defining component of the Cold War.

Strategic nuclear weapons are targeted against civilian, industrial, and military infrastructure, while tactical nuclear weapons are intended for battlefield use. Strategic weapons led to the development of dedicated intercontinental ballistic missiles, submarine-launched ballistic missile, and nuclear strategic bombers, collectively known as the nuclear triad. Tactical weapons options have included shorter-range ground-, air-, and sea-launched missiles, nuclear artillery, atomic demolition munitions, nuclear torpedos, and nuclear depth charges, but they have become less salient since the end of the Cold War.

As of 2025, there are nine countries on the list of states with nuclear weapons, and six more agree to nuclear sharing. Nuclear weapons are weapons of mass destruction, and their control is a focus of international security through measures to prevent nuclear proliferation, arms control, or nuclear disarmament. The total from all stockpiles peaked at over 64,000 weapons in 1986,[2] and is around 9,600 today.[3] Key international agreements and organizations include the Treaty on the Non-Proliferation of Nuclear Weapons, the Comprehensive Nuclear-Test-Ban Treaty and Comprehensive Nuclear-Test-Ban Treaty Organization, the International Atomic Energy Agency, the Treaty on the Prohibition of Nuclear Weapons, and nuclear-weapon-free zones.
