General Motors Lambda Platform
Lambda is General Motors full-size or mid-size 3-row crossover SUV automobile platform. It is largely derived from the GM Epsilon platform, which underlies the Chevrolet Malibu sedan and similar models. The Buick Enclave concept car was previewed at the 2006 North American International Auto Show, and the Saturn Outlook was shown at the 2006 New York Auto Show. The 2007 Outlook and GMC Acadia went into production in late 2006, followed by the 2008 Enclave in mid-2007, and the 2009 Chevrolet Traverse in mid-2008. Lambda vehicles feature easily accessible three-row seating. They were supplied with the LY7 3.6-liter V6. Starting with the 2009 model year all Lambda vehicles have GM LLT 3.6-liter gasoline direct injection engine for improved fuel efficiency, horsepower and torque. With the cancellation of GM's next-generation DOHC V8, there would be no V8 powertrain for the Lambda platform. The platform has been designed for front and all-wheel drive applications. Lamb ...

Automobile Platform
A car platform is a shared set of common design, engineering, and production efforts, as well as major components, over a number of outwardly distinct models and even types of cars, often from different, but somewhat related, marques. It is practiced in the automotive industry to reduce the costs associated with the development of products by basing those products on a smaller number of platforms. This further allows companies to create distinct models from a design perspective on similar underpinnings. A car platform is not to be confused with a platform chassis, although such a chassis can be part of an automobile’s design platform, as noted below. Definition and benefits A basic definition of a platform in cars, from a technical point of view, includes: underbody and suspensions (with axles) — where the underbody is made of front floor, Rearfloor, engine compartment and frame (reinforcement of underbody). Key mechanical components that define an automobile platform includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
All-wheel Drive
An all-wheel drive vehicle (AWD vehicle) is one with a powertrain capable of providing power to all its wheels, whether full-time or on-demand. The most common forms of all-wheel drive are: ;1x1 : All unicycles Reflecting one axle with one wheel capable of being powered. ; 2x2 : Some motorcycles and bikes Reflecting two axles with one wheel on each capable of being powered. ; 4×4 (also, four-wheel drive and 4WD): Reflecting two axles with both wheels on each capable of being powered. ; 6×6 (also, six-wheel drive and 6WD): Reflecting three axles with both wheels on each capable of being powered. ;8×8 (also, eight-wheel drive and 8WD): Reflecting four axles with both wheels on each capable of being powered. Vehicles may be either part-time all-wheel drive or full-time: ;On-demand (also, part-time): One axle is permanently connected to the drive, the other is being connected as needed ;Full-time (also, permanent): All axles are permanently connected, with or without a di ...

Front-wheel Drive
Front-wheel drive (FWD) is a form of engine and transmission layout used in motor vehicles, where the engine drives the front wheels only. Most modern front-wheel drive vehicles feature a transverse engine, rather than the conventional longitudinal engine arrangement generally found in rear-wheel drive and four-wheel drive vehicles. Location of engine and transmission By far the most common layout for a front-wheel drive car is with the engine and transmission at the front of the car, mounted transversely. Other layouts of front-wheel drive that have been occasionally produced are a front-engine mounted longitudinally, a mid-engine layout and a rear-engine layout. History Prior to 1900 Experiments with front-wheel drive cars date to the early days of the automobile. The world's first self-propelled vehicle, Nicolas-Joseph Cugnot's 1769/1770 "fardier à vapeur", was a front-wheel driven three-wheeled steam-tractor. It then took at least a century, for the first e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V8 Engine
A V8 engine is an eight-cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. The first V8 engine was produced by the French Antoinette company in 1904, developed and used in cars and speedboats but primarily aircraft; while the American 1914–1935 ''Cadillac L-Head'' engine is considered the first road going V8 engine to be mass produced in significant quantities. The popularity of V8 engines in cars was greatly increased following the 1932 introduction of the ''Ford Flathead V8''. In the early 21st century, use of V8 engines in passenger vehicles declined as automobile manufacturers opted for more fuel efficient, lower capacity engines, or hybrid and electric drivetrains. Design V-angle The majority of V8 engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations; however, the downside is a larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DOHC
An overhead camshaft (OHC) engine is a piston engine where the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam".) engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; however an OHV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GM Ultra Engine
Ultra was the codename for General Motors' next-generation family of DOHC V8 engines that was being developed to replace the Northstar as the V8 engine of choice for GM's premium vehicles. There is very little information on the engine's specifications currently available, however its lowest displacement would presumably have been similar to the Northstar's, (with higher-displacement versions probable as well), and it would very likely have incorporated technologies from the High Feature V6 family, including continuously variable valve timing on both intake and exhaust ports, as well as provision for gasoline direct injection. These engines would probably have been adaptable for both longitudinal and transverse applications (the latter would have been used by the rumored V8-powered versions of the Lambda crossover SUVs). Despite previously revealing plans to allocate production to the Tonawanda Engine plant, GM canceled development of this engine in January 2008. The 2013 Cad ...

Fuel Efficiency
Fuel efficiency is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical potential energy contained in a carrier (fuel) into kinetic energy or work. Overall fuel efficiency may vary per device, which in turn may vary per application, and this spectrum of variance is often illustrated as a continuous energy profile. Non-transportation applications, such as industry, benefit from increased fuel efficiency, especially fossil fuel power plants or industries dealing with combustion, such as ammonia production during the Haber process. In the context of transport, fuel economy is the energy efficiency of a particular vehicle, given as a ratio of distance traveled per unit of fuel consumed. It is dependent on several factors including engine efficiency, transmission design, and tire design. In most countries, using the metric system, fuel economy is stated as "fuel consumption" in liters per 100 kilometers (L/100 km) or kilometer ...

Gasoline Direct Injection
Gasoline direct injection (GDI), also known as petrol direct injection (PDI), is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber. This is distinct from manifold fuel injection systems, which inject fuel into the intake manifold. The use of GDI can help increase engine efficiency and specific power output as well as reduce exhaust emissions. The first GDI engine to reach production was introduced in 1925 for a low-compression truck engine. Several German cars used a Bosch mechanical GDI system in the 1950s, however usage of the technology remained rare until an electronic GDI system was introduced in 1996 by Mitsubishi for mass-produced cars. GDI has seen rapid adoption by the automotive industry in recent years, increasing in the United States from 2.3% of production for model year 2008 vehicles to approximately 50% for model year 2016.

GM High Feature Engine
The GM High Feature engine (also known as the HFV6, and including the 3600 LY7 and derivative LP1) is a family of modern General Motors DOHC V6 engines. The series was introduced in 2004 with the Cadillac CTS and the Holden Commodore (VZ). It is a 60° 24-valve design with aluminum block and heads and sequential multi-port fuel injection. Most versions feature continuously variable cam phasing on both intake and exhaust valves and electronic throttle control. Other features include piston oil-jet capability, forged and fillet rolled crankshaft, sinter forged connecting rods, a variable-length intake manifold, twin knock control sensors and coil-on-plug ignition. It was developed by the same international team responsible for the Ecotec, including the Opel engineers responsible for the 54° V6, with involvement with design and development engineering from Ricardo plc. Holden sold a HFV6 engine under the name Alloytec. The High Feature moniker on the Holden produced engine is res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New York Auto Show
The New York International Auto Show is an annual auto show that is held in Manhattan in late March or early April. It is held at the Jacob Javits Convention Center. It usually opens on or just before Easter weekend and closes on the first Sunday after Easter. In 2018, the NYIAS took place from March 30 through April 8. The show has been held annually since 1900. It was the first automotive exhibition in North America. The show was held at the New York Coliseum from 1956 to 1987 when the show moved to the Javits Center. Before the show opens every year, several auto companies debut new production and concept vehicles for the press. In addition, the Greater New York Auto Dealers Association (GNYADA) and the International Motor Press Association (IMPA) host corporate meetings and events.

North American International Auto Show
The North American International Auto Show (NAIAS), also known as the Detroit Auto Show as of 2022 and prior to NAIAS, is an annual auto show held in Detroit, Michigan, U.S., at Huntington Place. The show was held in January from 1989 to 2019. It was intended to move to the summer in 2020, but was canceled due to the COVID-19 pandemic that year and 2021, before returning in September 2022. It is among the largest auto shows in North America. UPI says the show is "regarded as the foremost venue for armanufacturers to unveil new products". The show begins with press preview days, industry preview days and a charity preview event. The charity preview raises money for local children's charities.
