Land Rover Discovery Sport
The Land Rover Discovery Sport (internal code L550) is a compact luxury crossover SUV produced by British automotive company Jaguar Land Rover since 2014, under their Land Rover marque, and since 2017 their best-selling model. Introduced in late 2014, it replaces the Freelander in a revised Land Rover range of vehicles, with Discovery joining Range Rover as a sub-brand. Contrary to its predecessor, the slightly larger car is also available in a seven seat layout. The pre-facelift Discovery Sport is based on the JLR D8/LR-MS platform, customised for off-road applications, and is powered by a range of four cylinder petrol and diesel engines. It is the first Discovery built with a unibody structure. Land Rover described the facelifted Discovery Sport as being based on the JLR PTA platform, a rebrand of the D8. It is also used by the Jaguar E-Pace and L551 version of Range Rover Evoque. Overview The Discovery Sport marked the third generation of compact SUV produced by ...

Petrol Engine
A petrol engine (gasoline engine in American and Canadian English) is an internal combustion engine designed to run on petrol (gasoline). Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as '' E10'' and '' E85''). They may be designed to run on petrol with a higher octane rating, as sold at petrol stations. Most petrol engines use spark ignition, unlike diesel engines which run on diesel fuel and typically use compression ignition. Another key difference to diesel engines is that petrol engines typically have a lower compression ratio. History The first practical petrol engine was built in 1876 in Germany by Nicolaus August Otto and Eugen Langen, although there had been earlier attempts by Étienne Lenoir in 1860, Siegfried Marcus in 1864 and George Brayton in 1873. Design Thermodynamic cycle Most petrol engines use either the four-stroke Otto cycle or the two-stroke cycle. Petrol engines have also ...

Compact Crossover SUV
Compact crossover SUV is an automobile classification used mainly in North America to describe a segment of crossover SUV, a type of sport utility vehicle, between subcompact crossover SUV and mid-size crossover SUV. By the late 2010s, the segment had emerged as the most popular automobile segment in several regions. For example, nearly one in every four cars sold in the United States in 2019 was a compact crossover, at about 24.2 percent. The best-selling vehicle in the segment in 2020 was the Toyota RAV4, with 995,762 units sold globally. It was also the second best-selling automobile in the world after the Toyota Corolla in 2021. Terminology The term "compact crossover SUV" is most commonly used in the North America, where the "compact car" and "crossover" terms originated. It is also known as C-segment SUV or C-SUV. The naming of the segment also differ depending on the market. In several regions outside North America, the category may be known as "mid-size/medium crosso ...

Automatic Transmission
An automatic transmission (AT) or automatic gearbox is a multi-speed transmission (mechanics), transmission used in motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. The 1904 Sturtevant "horseless carriage gearbox" is often considered to be the first true automatic transmission. The first mass-produced automatic transmission is the General Motors ''Hydramatic'' two-speed hydraulic automatic, which was introduced in 1939. Automatic transmissions are especially prevalent in vehicular drivetrains, particularly those subject to intense mechanical acceleration and frequent idle/transient operating conditions; commonly commercial/passenger/utility vehicles, such as buses and waste collection vehicles. Prevalence Vehicles with internal combustion engines, unlike electric vehicles, require the engine to operate in a narrow range of rates of rotation, requiring a gearbox, operated manually or automatically, to drive t ...

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canadian English, Canada, British English, the United Kingdom and American English, the United States), or stick shift (in the United States), is a multi-speed motor vehicle Transmission (mechanical device), 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 ...

Reluctance Motor
A reluctance motor is a type of electric motor that induces non-permanent magnetic poles on the ferromagnetic rotor. The rotor does not have any windings. It generates torque through magnetic reluctance. Reluctance motor subtypes include synchronous, variable, switched and variable stepping. Reluctance motors can deliver high power density at low cost, making them attractive for many applications. Disadvantages include high torque ripple (the difference between maximum and minimum torque during one revolution) when operated at low speed, and noise due to torque ripple. Until the early twenty-first century, their use was limited by the complexity of designing and controlling them. Advances in theory, computer design tools, and low-cost embedded systems for control overcame these obstacles. Microcontrollers use real-time computing control algorithms to tailor drive waveforms according to rotor position and current/voltage feedback. Before the development of large-scale integrat ...

Mild Hybrid
Mild hybrids (MHEV) (also known as smart hybrids, power-assist hybrids, battery-assisted hybrid vehicles or BAHVs) are generally cars with an internal combustion engine (ICE) equipped with a minimally extended battery and an auxiliary electric combined motor and generator in a parallel hybrid configuration that is only enough for an electric-only mode of propulsion at slow speed and allows the engine to be stopped whenever the car is coasting, braking, or stopped, and then restarted once power is required again. Mild hybrids may employ regenerative braking and some level of power assist to the internal combustion engine. Overview The mild hybrid's electric motor provides greater efficiency through the use of a single device that is essentially an integrated starter/alternator sometimes known as a generator-motor unit. A typical mild-hybrid setup uses a belt-powered generator-motor unit driven off the engine to supply power to a small battery. The generator is also powered throug ...

Plug-in Hybrid Electric Vehicle
A plug-in hybrid electric vehicle (PHEV) or simply plug-in hybrid is a type of hybrid electric vehicle equipped with a rechargeable battery pack that can be directly replenished via a charging cable plugged into an external electric power source, in addition to charging internally by its on-board internal combustion engine-powered generator. While PHEVs are predominantly passenger cars, there are also plug-in hybrid variants of sports cars, commercial vehicles, vans, utility trucks, buses, trains, motorcycles, mopeds, military vehicles and boats. Similar to battery electric vehicles (BEVs), plug-in hybrids can use centralized generators of renewable energy (e.g. solar, wind or hydroelectric) to be largely emission-free, or a fossil plant in which case they displace greenhouse gas emissions from the car tailpipe exhaust to the power station. As opposed to conventional hybrid electric vehicles (HEVs), PHEVs generally have a larger battery pack that can be recharged (th ...
