Automatic vs Semi-Automatic vs Manual - Part II

Background MANUAL. Manual transmissions were the first and most common type of transmission to be fitted in cars to benefit from different gear ratios between the respective propulsion of engine and drivetrain. They basically involve the activation by the driver of the clutch by a foot pedal, the positioning of gears by a gear stick, and the respective coordination of the fuel supply through a throttle pedal. Manual transmissions cost less to manufacture and their reparation in case of malfunction is less complex and costly than that of automated ones. As compared with fully automated devices, it also allows for a potential greater fuel efficiency (albeit not necessarily) as the driver can judge what especial conditions of driving allow for taller ratios and lower supply of fuel. The risk of engine breakdown due to over-revving has additionally been significantly reduced through the fitting of electronic rev-limiters. More significantly, however, the greater advantage of manuals lies in the substantially different driving experience. Automobiles with manual gearboxes situate the driver in command of all the important functions of the vehicle, such as gear selection, amount and duration of clutch activation, fuel supply, all of whose related combinations allow for an infinite range of subtle variations of the dynamics of the machine. Automobile enthusiasts, that is, individuals related to vehicles seeking the sensorial experience of driving for its own sake rather than as a means of transport or of merely attempting to move measurably faster, tend to value all the mechanical operations implied by active driving rather than seeking promised marginal gains in speed by the delegation of functions to the vehicle's automated systems. The experience of directly controlling and operating the main variables and functions of the vehicle and for the driver to be organically integrated with the whole of the machine is believed to be of greatest appeal to car enthusiasts.

Automatic vs Semi-Automatic vs Manual - Part I
Top Gear © BBC 2002-2009 / Fifth Gear © Channel Five 2004-2009 [THIS IS A COMPILATION OF CLIPS] Background AUTOMATIC. Automated transmissions were developed early in the inception of cars with internally-combusted engines. Diverse mechanisms were devised to autonomously operate changes benefiting from distinct ratios between engine and wheel motion. The most common device in automobiles is a hydraulically-operated one, using fluid coupling or a torque converter and a set of planetary gearsets providing different ratios. The introduction of automatic gearboxes in transit was anthropologically significant as it allowed far larger populations to drive vehicles, including people who had learned to drive at a late age or people simply not apt to operate the mechanism of manual gearboxes (coordinating clutch pedal + gear stick + throttle pedal). This fact is important as the formidable societal transformation of the transition to an individually mobile society and the economic and industrial transformation after Second World War were both brought about by the massive socialisation, production and use of automobiles. Individual transportation benefited business operability and efficiency as employees and business partners gained greater geographic mobility but also individuals, as this increased, more flexible mobility allowed an enhanced disposal of time and space in the private sphere. These facts, however, only marginally explain the recent trend increasing the proportion of cars with automated transmissions in the car market; this tendency rather follows a very concrete commercial strategy by car manufacturers. Automated transmissions (automatics and semi-automatics) tend to be subject to marginally fewer mechanical breakdowns than manuals, notably those derived by engine over-revving, and also tend to be involved in marginally fewer road accidents. Additionally, engines matted to automatics tend to be better conserved over time and generate lower warranty costs. These facts also redound in lower insurance rates and higher resale values for used cars. These facts have hence moved manufacturers to equip these more costly gearboxes to their models, more notably so in the case of premium manufacturers, as higher resale values for used cars move customers to opt for more similarly priced, brand new vehicles. Background SEMI-AUTOMATIC. The commercial policy described above is more financially beneficial to premium manufacturers as initial purchase costs are often more flexible than those for more economic cars. In this trend, manufacturers of so called sports and race cars, such as Ferrari, Porsche, Lamborghini, BMW and others, began to progressively fit automated gearboxes to their vehicles as well, seeking, however, to provide devices that allowed drivers to operate gear changes manually, even if not through direct, mechanical commands. Automated gearboxes with drivers input were devised by motor sport teams in categories such as Formula 1 and World Rally Championship in the late 1980s, seeking to improve mechanical reliability but also time efficiency, reducing the lapse of gear-ratio changes. These devices finally became standard in both categories by the mid 1990s. There are two basic types of semi-automatic transmissions: Planetary, torque-converting automatic transmissions fitting devices that allow electronic inputs by the driver to operate gear selections; they are far less expensive and are correspondingly more commonly fitted. The second type is that of manual gearboxes fitting individual motors operating clutch activation, gearset engagement and throttle coordination; they are in general much more expensive and fitted less frequently (e.g. Ferrari and some BMW models). The greatest disadvantage of automated manuals seems to lie in the less accomplished operation of changes. Drivers commands are always integrated via electronic inputs (clutch-less stick or, more commonly, so called flappy-paddles behind the steering wheel) within the computerised systems of the vehicle: engine-, traction-, stability-, brake- and more recently (electro-hydraulic) steering-management. Manufacturers have justified the fitting of semi-automatics with a claimed gain in time efficiency, rendering a car marginally faster as dead times, clutch intervals, are said to be operated faster. The most recent device in this trend is the dual-clutch transmission (DCT), in which an additional clutch pre-engages the next gear to that transmitting motion, so that when the order for a gear change is given the next gear is immediately operative.

CVT Paddle Shifting vs Formula 1 PDK (Doppelkupplung)
CVT Paddle Shifting vs Formula 1 PDK - (Doppelkupplung Dual-Clutch) Get the book here: https://www.createspace.com/4283730 https://www.createspace.com/371853 Ok, so what does CVT technology has to do with Formula-1 technology? The answer is, you're right, absolutely nothing. However, in an ever increasing move to adapt and accept CVT technology, some manufacturers have installed the paddle style Formula-1 shift on CVT vehicles. This move is a complete negation of the benefits of CVT, and a waste of money for the consumer. In this article we'll explain the differences between the two technologies and how they work, to allow you to make a decision. We encourage you to go elsewhere in this series, for more on CVT technology. The newer semi-automatic dual clutch transmissions, are a direct result of years of Formula 1 technology. These transmissions are directly related to the manual, standard stick shift dry clutch transmissions that we all know. However, the semi- automatic, also known as PDK for their German name, effect the actual shifting using either servo hydraulic, or electric actuators, using a paddle shifter on the steering wheel. This is exactly the same technology used in Formula 1 racing cars. Lots of automotive technology first starts in the Formula 1 circuit, then trickles down to mass produced cars. Paddle shifted PDK semi-automatic transmissions, are the latest and most advanced gearboxes today. These units have all the benefits of a manual transmission, including fuel economy, have no torque converter, no gear wet clutches, and are fully computerized and able to operate as a normal automatic. There are two types of paddle shifted PDK semi-automatic transmission, the single dry clutch, and the more advanced ... Get the whole story right here in this video...

Rear-Wheel Drive vs Front-Wheel Drive vs All-Wheel Drive
Top Gear © BBC 2000. "Old Top Gear", broadcast on 09 March 2000 [LOW VIDEO QUALITY] Vicky Butler-Henderson (Fifth Gear) tests and compares three different automotive drivetrains: rear-wheel drive (RWD), front-wheel drive (FWD) and all-wheel drive (AWD). NOTE: It must be noted that the Audi A4 quattro was a vehicle developed primarily as a front-wheel and not an all-wheel drive car, with most of its kinetic layout (weight distribution, suspension structure, relative wheel distribution, etc.) conceived for front-wheel propulsion. It has a traction torque bias towards the front wheels. Neither was it equipped with active limited-slip differentials (i.e. front- or rear axles or in the shaft in-between) to distribute torque/traction as per contingent wheel grip. By contrast other front-engined, all-wheel drive vehicles (i.e. Subaru Impreza WRX STi, Mitsubishi Lancer Evo) are conceived from the onset with permanent and symmetrical all-wheel drive systems and are often equipped with various arrays of slip differentials in the front- and rear axles and in the torque shaft, resulting in an altogether significantly different vehicle dynamic behaviour. It should also be mentioned that since the broadcast of this film, several traction systems have been developed, for both front and all-wheel drive vehicles, notably mechanical or electronic differentials for front-wheel drive cars e.g. those developed by Alfa Romeo, Ford, Citroën or Nissan. Finally, it should be noted that the criteria for this test was to determine traction on dry tarmac, asphalt sufaces, and not loose ground such as wet tarmac, gravel, sand, snow or mud, contexts in which the dynamic results would most probably vary. It is generally agreed that they do so in favour of (permanent) all-wheel drive or (selectable) four-wheel drive systems, also given the possibility of dual-range transmissions (including greater torque conversion) © Video Copyrights: Top Gear, BBC & BBC World, 2000.

It does not intend to reflect the current state of development of the most recent transmission technologies, nor their efficiency. Please note the video was filmed in 2003 when semi-automated systems had not experienced the considerable improvement they later did in the late 2000's. Crucially, none of the cars with automated transmissions on this video feature Double-Clutch Transmission (DCT) technologies, which have in recent years considerably improved aspects such as manual activation, gearshift order delays and inter-gear time-lapses. Tested vehicles: o Mitsubishi Evo VII GSR YELLOW ( MANUAL) o Mitsubishi Evo VII GT-A (*) CHAMPAGNE (AUTOMATIC) o BMW M3 [E46] SILVER ( MANUAL) o BMW M3 [E46] SMG II MUSTARD (SEMI-AUTOMATIC) o Ferrari 360 Modena RED ( MANUAL) o Ferrari 360 Modena F1 WHITE (SEMI-AUTOMATIC) (*) Please note the Mitsubishi Evo VII GT-A automatic has a -8 HP disadvantage over the equivalent GSR, Manual model. © Video Copyrights: Best Motoring International, Japan, 2003.
