Decoding Automated Manual Transmission

AMT Gearbox
             Hello friends welcome to my blog http://techsonwheel.blogspot.in/. Automated Manual Transmission (AMT) (also known as clutchless manual transmission or semi-automatic manual transmission) in an automobile transmission that does changes gear automatically rather facilitates manual gear changes by dispensing the need to press a clutch pedal at the same time as changing gears. It uses electronic sensors, actuators, pneumatics and processors to change gears on the command of driver or by a computer. AMT is not a new system it had early employed in European automobiles before applying it in Indian market.
            
            Maruti Suzuki Celerio is the first car in India to be equipped with AMT technology. This technology is perfect for Indian buyer as it provides a hassle free city commutes without burning a hole in our pocket.  This car was employed in Europe but was successful as the drive was not jerk free or seamless like automatic gearboxes. Moreover the gear shifts per kilometre are fewer than countries like India and they are not obsessed with “Kitna deti hai”. So either they made out with manual gearbox or paid extra a bit for automatic gearbox.

AMT is perfect for technology for India. It gives the driver of peace of mind for clutch less shifts while moving around in metropolitan cities which they die for, it’s also fuel efficient like manual gearbox and it’s a cheap technology that doesn’t increases the price of car too much. Maruti was able to launch Celerio at a price of ₹ 4.3 Lakhs ex-showroom.

The Celerio was first launched in Delhi Auto Expo 2014 by Maruti. The show stopper then was not the car it was the technology that was used in the car to drive it. Maruti Suzuki went on with Magneti Marelli 4th generation AMT technology because the brains behind the Celerio tells that Magneti Marelli system is an excellent balance between efficiency and cost, that is specially made for Indian market.

In a conventional manual gearbox a set of cables or link usually operates the gearbox in two step processes i.e. selection and engagement of gears. So in Automatic Manual gearbox or AMT essentially replaces the mechanical linkages by electromechanical individual devices that work off the engine management and transmission management control units. The electronically controlled clutch actuator uses an electric motor to operate the clutch instead of a conventional pedal and cable operated setup. The pioneers of the AMT gearbox claims that this setup not only stimulates clutch-less driving but also increases the longevity of clutch components  and increases fuel economy.

In an AMT, the electromechanical or hydraulically operated actuators take over the clutch and the shift action. This is predominantly due to the fact that the driver can still choose to manually engage a particular gear either by shifter lever or by paddle shifters mounted on steering wheel. AMTs also help to reduce the torque intervention during changing gears manually. An array of sensors is present to monitor the driving conditions and gives it to Transmission Control Module or TCU which processes the information and reacts accordingly to the driver based input.

The other Indian brands Tata (with Zest) and Mahindra (with Quanto) have expressed their willingness to adopt AMT as their transmission. But according to reports it says that unlike Celerio’s Magneti Marelli AMT, Tata & Mahindra uses AMT developed by ZF. The AMT system is developed to enhance the driving pleasure without the use of the stick and provide hassle free journey in the busy roads of India without hampering the fuel economy. AMT has a great future in India unlike Europe due its benefits.

Got a burning question in mind post it in the comment section right below. Thank you.

Stingray Reincarnated

Hello friends welcome to my blog http://techsonwheel.blogspot.in/. This year we are noticing the 20th tournament of FIFA World Cup in Brazil. It is the most anticipated game of the year. Brazil has noticed their automotive revolution after Chevrolet rolled off their assembly line in 1925. With all these years leaving in past the company has moved forward along with the motto of Brazil “Ordem e Progresso” i.e., “Order and Progress”.
2015 Chevrolet Corvette Z06

                The Chevrolet Corvette C7 or Z06 is a sports car produced by Chevrolet division of General Motors. The new 2015 Corvette Stingray is the beauty of design and engineering with new advanced technologies, supercharged engines and race proven bloodline it’s a super car in the new territory. The Corvette Z06 is one of the industries only supercars to achieve over 600+ hp under its hood with its big 6.2L supercharged V8.
               
                   The Z06 elevates us to new level of experience of driving the new lightweight but rigid space aluminium frame, carbon fibre body works with removable roof top, chassis architecture, engine technologies and aerodynamic strategies. The Z06 itself envelopes within, the performance of street and track car. The Z06 has cosmetic upgrade of its sibling Stingray. The Chevrolet replaced the standard set of tires with new sets of larger Michelin summer only tires. The car has wider fender to accommodate larger tyres for more grip on any track. Its unique honey comb grill at front serves a better flow of air for cooling purposes. It also has larger spoiler to keep the car stick to tracks.  The new Z06 features Carbon Fibre hood and removable carbon fibre roof panel which helps to keep the centre of gravity low and maintaining optimal weight distribution for precise handling.

                The interior of the car driver focused cockpit and can be easily differentiated between from Stingray. The esteemed customers can choose from two different seat versions- a GT for all round comfort and support and Competition seat with aggressive side bolstering, which provides greater support on track. The model also offers premium soft touch Napa leather material, aluminium, and carbon fibre and suede microfiber.

                The Corvette Z06 is powered by 6.2L Supercharged V8 delivering at least 625hp and 635lb/ft of torque at your ease. The small block’s 625lb/ft of torque peaks at 3600rpm. The engine continues to make 90% of peak torque or 592lb/ft of torque from 2500-5400rpm. The supercharger of Z06 is smaller but sin faster allowing for instantaneous power whenever required. In addition the engine has lightweight titanium intake valves and connecting rods for reduced reciprocating mass. To increase the fuel efficiency of the engine, the corvette stingray introduced Direct Injection, Active Fuel Management and Continuously Variable Valve Timing. The Z06 offers two choices of transmission- a 7 speed manual gearbox or all new track certified 8-speed automatic dual clutch gearbox for delivery of high performance without sacrificing refinement. In the central console of the car it has the wheel for drive mode selector between driving modes: Weather, Eco, Tour, Sport and Track. Each mode electronically calibrates the performance variables to customize and optimize the Corvette Z06 supercar for any road.

                The Corvette Z06 convertible is built on same rather chassis as of the coupe versions. The convertible Z06 delivers the same optimal performance like the coupe. The Z06 takes 0-60mph in 3.4secs and acquiring a top speed of 205mph.

                At the price point the Z06 has got two rivals standing on their way i.e. 2015 SRT Viper ACR and Ferrari 458 Speciale. I would let you decide which one to choose from.


                The 2015 Corvette Z06 put all supercar manufactures on the notice with its 625 horsepower engine under its hood.

                 So as the FIFA fever is going fast its also moves fast within a fraction of secs.Got any queries to ask write it in comment box below.
