Shift Blocking
Shift blocking is a feature of automobile manual transmissions added to improve fuel economy ratings in the Corporate Average Fuel Economy (CAFE) system by preventing a driver from switching from first gear to second or third as would be done normally. A solenoid prevents the shifter from engaging these gears, forcing the driver to shift from first to fourth gear. The solenoid is computer controlled, and will deactivate if the throttle is opened wide enough, or the car reaches speeds above those typical in city driving. Usage The skip shift feature was originally introduced in the Chevrolet Corvette in the late 1980s, with the name CAGS (Computer-Aided Gear Selection), and is present on many sporting cars produced in the US from the 1990s onwards on every car fitted with the Tremec T-56 and TR-6060, including the Dodge Viper, Pontiac Firebird, 2004-2006 Pontiac GTO, Pontiac G8 GXP, V8/SS Chevrolet Camaro and Cadillac CTS-V The Cadillac CTS is an executive car that was manuf ...

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom, and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission (mechanics), transmission system, where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission; common types of automatic transmissions are the Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic transmission (AT), and the continuously variable transmissio ...

Chevrolet Corvette
The Chevrolet Corvette is a two-door, two-passenger luxury sports car manufactured and marketed by Chevrolet since 1953. With eight design generations, noted sequentially from C1 to C8, the Corvette is noted for its performance and distinctive fiberglass or composite panels. It was front-engined through 2019 and mid-engined since. The Corvette is currently the only two-seat sports car produced by a major United States auto manufacturer and it serves as Chevrolet's halo vehicle. In 1953, GM executives accepted a suggestion by Myron Scott, then the assistant director of the Public Relations department, to name the company's new sports car after the corvette, a small maneuverable warship. The first model, a convertible, was introduced at the 1953 GM Motorama as a concept car; production models went on sale later that year. In 1963, the second generation was introduced in coupe and convertible styles. Originally manufactured in Flint, Michigan, and St. Louis, Missouri, the C ...

Production of the two-seat super car began at New Mack Assembly Plant in 1991 and moved to Conner Avenue Assembly Plant in October 1995. Although Chrysler considered ending production because of serious financial problems, on September 14, 2010, the then chief executive Sergio Marchionne announced and previewed a new model of the Viper for 2012.

Pontiac Firebird
The Pontiac Firebird is an American automobile that was built and produced by Pontiac from the 1967 to 2002 model years. Designed as a pony car to compete with the Ford Mustang, it was introduced on February 23, 1967, five months after GM's Chevrolet division's platform-sharing Camaro. This also coincided with the release of the 1967 Mercury Cougar, Ford's upscale, platform-sharing version of the Mustang. The name "Firebird" was also previously used by GM for the General Motors Firebird in the 1950s and early 1960s concept cars. First generation (1967–1969) The first generation Firebird had characteristic Coke bottle styling shared with its cousin, the Chevrolet Camaro. Announcing a Pontiac styling trend, the Firebird's bumpers were integrated into the design of the front end, giving it a more streamlined look than the Camaro. The Firebird's rear "slit" taillights were inspired by the 1966–1967 Pontiac GTO and Pontiac Grand Prix. Both a two-door hardtop and a conver ...

Chevrolet Camaro
The Chevrolet Camaro is a mid-size American automobile manufactured by Chevrolet, classified as a pony car. It first went on sale on September 29, 1966, for the 1967 model year and was designed to compete with the Ford Mustang. The Camaro shared its platform and major components with the Firebird, produced by General Motors' Pontiac division that was also introduced for 1967. Four distinct generations of the Camaro were developed before production ended in 2002. The nameplate was revived on a concept car that evolved into the fifth-generation Camaro; production started on March 16, 2009.

Cadillac CTS-V
The Cadillac CTS is an executive car that was manufactured and marketed by General Motors from 2003 until 2019 across three generations. Historically, it was priced similarly to cars on the compact luxury spectrum; but it has always been sized closely to its mid-size rivals. The third generation competes directly with the mid-size luxury cars. Initially available only as a 4-door sedan on the GM Sigma platform, GM had offered the second generation CTS in three body styles: 4-door sedan, 2-door coupe, and 5-door sport wagon also using the Sigma platform — and the third generation was offered only as a sedan, using a stretched version of the GM Alpha platform. The third-generation CTS's indirect successor is the smaller CT5, which, like the first- and second-generation CTS, takes on the BMW 3 Series and Mercedes-Benz C-Class, while maintaining its 5 Series/E-Class size. Wayne Cherry and Kip Wasenko designed the exterior of the first generation CTS, marking the production debu ...

Engine Control Unit
An engine control unit (ECU), also commonly called an engine control module (ECM), is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance. It does this by reading values from a multitude of sensors within the engine bay, interpreting the data using multidimensional performance maps (called lookup tables), and adjusting the engine actuators. Before ECUs, air–fuel mixture, ignition timing, and idle speed were mechanically set and dynamically controlled by mechanical and pneumatic means. If the ECU has control over the fuel lines, then it is referred to as an electronic engine management system (EEMS). The fuel injection system has the major role of controlling the engine's fuel supply. The whole mechanism of the EEMS is controlled by a stack of sensors and actuators. Workings Control of air–fuel ratio Most modern engines use some type of fuel injection to deliver fuel to the cylinders. ...
