Highway travels within the close to future is not going to embrace lengthy strains at toll plazas, serving to you save time
Over a decade in the past, the gathering of tolls on highways was purely executed in money or by way of playing cards, till FASTags had been launched in 2014. The introduction of FASTags made the toll fee course of faster and extra seamless, however Union Minister Nitin Gadkari is planning to make FASTags and even toll plazas utterly out of date with a brand new satellite-based toll assortment system. Learn extra about what it’s and the way it works on this detailed article.
What Is GPS Based Toll Collection
Unlike our conventional method of paying tolls whereas travelling, the place there are toll assortment plaza on highways the place you must cease, wait in line, and pay the toll by way of FASTag; the GPS or satellite-based toll assortment system will incorporate monitoring programs put in in automobiles that may measure the gap travelled by your automobile and the toll might be charged based mostly on the gap you may have lined.
In this course of, because the information from the monitoring gadget is shared straight with the satellite tv for pc, the presence of toll plazas is not going to be required which is able to make the drive much more handy by serving to you save the time you spend ready in strains.
How Will It Work
The implementation of this new methodology is not going to be straightforward and it’ll take a couple of years for each automobile to be outfitted with the know-how. However, if carried out efficiently, that is how the method will work.
The automobiles should be outfitted with an OBU (on-board unit) which is the aforementioned monitoring gadget.
The OBU will observe the coordinates of your automobile when you’re driving on highways and people coordinates might be shared with the satellite tv for pc to calculate the gap you may have travelled.
This system will work utilizing GPS (Global Positioning System) which is able to function utilizing the GNSS (Global Navigation Satellite System) that may assist preserve accuracy within the distance calculation.
The cameras positioned on these highways can be utilized to make sure that the gap is being measured correctly by evaluating the coordinates of the automobile with the picture taken. The digicam may assist in discovering out which automobiles don’t have OBUs by working the quantity plates.
Initially, this toll assortment system might be carried out on choose highways and expressways throughout the nation.
With this methodology of toll assortment, the quite a few toll plazas positioned on the highways and expressways might be eliminated, and you wouldn’t must decelerate which might make your journeys barely faster.
The OBUs will not be already current in automobiles however should be put in externally. As of now, there is no such thing as a details about how and the place to get these OBUs, however the course of won’t be so troublesome, and is likely to be just like FASTags after they had been initially launched. This is how we expect the method might be.
Much like FASTags, these OBUs might be out there by means of authorities web sites, the place you’ll have the ability to get them organized by placing your automobile’s registration quantity and finishing a KYC.
Once you apply for the OBU, you’ll must get it linked to your checking account.
After the implementation of this toll assortment system, automobile producers would possibly simply begin promoting their automobiles with pre-installed OBUs, which you’ll then hyperlink to your checking account.
Just like FASTags, banks and personal firms may also begin promoting OBUs.
After putting in the OBU within the automobile, based mostly on the gap travelled, the toll quantity might be robotically deducted out of your linked checking account.
Will It Work In India?
The GPS-based toll assortment system will not be one thing new because it has already been carried out in nations like Germany and Singapore, and this method has labored in these nations. In India, the transfer in direction of digital transactions and know-how is at a quick tempo, which could simply make this new toll assortment system work, and its adoption may even not take a lot time as soon as vast scale implementation begins.
However, to do that, the present infrastructure based mostly round FASTags should be eliminated, the brand new infrastructure should be created, which is not going to solely take time, however may even be costly. The price of changing your complete infrastructure might find yourself on the shopper within the type of elevated toll costs.
As of now, the thought of this new system appears nice, however the implementation and adoption is not going to be straightforward. If the federal government begins to work on it now, we’ll have to attend for round a decade for it to be carried out throughout the nation.

General Motors has an extended historical past of creating modern strides in engine improvement. The Chevrolet small-block V-8, for instance, started life within the Fifties and shortly turned the usual for top horsepower in a small bundle, a legacy that continues into right this moment’s fifth-generation GM V-8s. Even GM’s lineup of V-6 engines made waves all through the business, starting from the 60-degree V-6 that powered practically each GM automobile from 1980 by 2010, to the twin-turbocharged V-6 powering the Cadillac ATS-V.
However, GM has a lesser-known engine household that deserves admiration for its outside-the-box pondering and excellent technological developments, the Atlas engine household. That Atlas household consisted of three principal engines; the front-running 4.2-liter inline-six, the three.5-liter five-cylinder, and the two.8-liter four-cylinder. All three shared the identical primary structure and a variety of elements, although it was the 4.2-liter that led the Atlas program. Here’s a more in-depth take a look at the technical points and historical past of GM’s Atlas 4.2-liter inline six.

The 4.2-Liter Atlas I-6’s History
To uncover the distinctive particulars of the GM Atlas engine, in any other case referred to as the Vortec 4200, we reached out to GM and located Tom Sutter, the Assistant Chief Engineer for the Atlas. Sutter has been concerned with engine applications for the final 30 years, starting from Oldsmobile’s Quad Four to Cadillac’s present V-Series mills.
Looking Towards Other GM Engines For Inspiration
During improvement, Tom Sutter reverted to his time growing the Oldsmobile Quad Four, GM’s first four-valve per cylinder engine, which was essentially a small-block Chevy inline-six engine. The same design was sketched for the Atlas and finally turned an integral a part of the challenge.
Twin overhead camshafts had been used to regulate the exhaust and consumption valves individually.
Furthermore, GM’s first stab at variable valve timing was put into place on the exhaust aspect. This allowed the GM inline-six engine to breathe deeper throughout high-throttle conditions, leading to larger energy with out the gas consumption penalty being current all through the rev vary. GM’s new modern valve cowl stored issues quiet below the hood, which was constructed utilizing a plastic-like composite materials.
GM even used its comparatively new manufacturing methodology for the Atlas engine block and cylinder head. Called the Lost Foam Casting method, it mainly makes use of a pre-shaped block of Styrofoam buried in sand. Molten aluminum is then poured in, filling the voids left by the melting foam. The result’s an excellent detailed engine block that requires little or no tough machining.
Its Impact On Motorsport
The GM Atlas engine additionally had a short-lived racing profession. General Motors contracted with Falconer, a specialty engine builder, to assemble a 5.0-liter, high-performance model of the Atlas inline-six.
It produced roughly 600 horsepower at 7,500 rpm and 450 pound-feet of torque at 6,000 rpm, however shared virtually no elements with the manufacturing engine.
Herzog Motorsports ran the vans fitted with the GM Atlas inline-six, with the primary race truck being the Vortec Trailblazer that ran in the Baja 500 and Baja 1000 off-road races in 2000. The one-off car was constructed with a tube-frame chassis and coated with a carbon-fiber physique. Driven by Larry Ragland, the 81 Vortec Trailblazer solely competed in these two Baja races, earlier than retiring to Ragland’s storage.
The GM Atlas Engine’s Diverse Potential
The 4.2-liter Atlas engine was a groundbreaking engine for GM. It featured an all-aluminum building, twin overhead cams with variable valve timing on the exhaust aspect, 4 valves per cylinder, a coil-on-plug ignition system, a excessive compression ratio of 10:1, and its cylinder heads featured GM’s then-prevalent “Vortec” engineering designed to maximise airflow.
Each of those mid-sized SUVs shared the identical cutting-edge structure, together with the business’s first totally hydroformed body in a mid-size SUV. Introduced for the 2002 mannequin 12 months, the GMT360 platform bought a pair million examples worldwide earlier than ending manufacturing after 2009.
Pushing The Industry Forward
GM additionally broke floor within the SUV section by utilizing a twin overhead camshaft with roller-followers to regulate the 4 valves per cylinder. The design was chosen due to the massive quantity of air 4 valves can transfer, whereas the roller-followers supplied a smoother operation with much less friction than typical lifters, including to the engine’s effectivity.
Thanks to the variety of valves, their sizes had been stored small to assist with cooling. Large coolant chambers had been routed across the valves and the center-mounted spark plugs, additional serving to the engine run cooler. Because of the environment friendly cooling and the decreased threat of detonation, the Atlas inline-six was capable of run its excessive compression ratio with out the necessity for premium gas.
The Further In-Depth Craftmanship For The Atlas Inline-Six
As effectively as utilizing twin overhead camshaft, GM’s Atlas inline-six engine featured further components that in the end led to its success. A brand new engine comes with new challenges, resulting in GM introducing all-new elements to extract from its giant fleet of SUVs on the time.
As talked about earlier than, the Vortec 4200 was the primary GM truck engine to characteristic variable valve timing. This early adopter solely had variable valve timing on the exhaust aspect, nonetheless, however allowed for 25 levels of exhaust cam phasing. This stored torque ranges at near-peak ranges all through the rev vary and allowed a higher maximum horsepower with out killing gas effectivity or hindering drivability at decrease RPM ranges.
A First-Of-Its-Kind drive-by-wire System
The Chevy Atlas engine was additionally managed by a drive-by-wire system, one other first in a GM truck software. The system used an digital throttle with no mechanical linkage between the gasoline pedal and the throttle physique, managed by the PCM and was opened through an electrical motor mounted contained in the 77-mm diameter throttle physique.
The modern consumption manifold featured a 180-degree bend, bringing air into the throttle physique simply above the engine and wrapping it round into the cross-flow cylinder head.
The consumption manifold was stored brief with the intention to accommodate easy accessibility to the spark plugs, including a much-welcomed contact of practicality.
Its Unique Mounting System
The GM Atlas inline-six additionally utilized an modern mounting system for its equipment. Each part moreover the ability steering pump was mounted on to the block. This consists of the alternator, A/C compressor, and loafer pulley. GM says this helped eradicate play within the belt-drive system since every part was completely positioned in relation to the block.
Key Takeaways:
The General Motors Atlas inline-six engine was first launched in 2002, getting used for autos such because the Chevrolet Trailblazer and GMC Envoy.
The Atlas engine was utilized in off-road race vans, which competing in iconic races such because the Baja 1000.
Smaller variations of the Atlas engines had been launched after the I-6’s success, together with the Vortec 3500 and the Vortec 2800.
Production of the GM Atlas engine resulted in 2009, as a result of dimension and prices of the engine not being a logical enterprise choice transferring ahead.
The End of an Era
Bring A Trailer
The Vortec 4200 was an enormous leap ahead for GM powertrains. But regardless of this, the modern inline-six didn’t take pleasure in an extended life. It was the cancelation of the GMT360 platform in 2009 that spelled the tip for the Vortec 4200.
The engine merely wouldn’t slot in different purposes. “The length of the engine and its structure definitely played a part in that,” Sutter mentioned. “The engine doesn’t work in a transverse application, so it was limited in the vehicle choices.”
The inline-six would theoretically have slot in GM’s full-size vans just like the Chevrolet Silverado and GMC Sierra. However, it was logistics that prevented that from taking place. Those vans used GM’s 4.3-liter V-6 as their base engine, which was based on the GM small-block V-8.
What Were The Other Atlas Engines?
Bring A Trailer
Two years after the Atlas inline-six, GM launched a smaller Atlas engine, named the Vortec 3500. Instead of six cylinders, the Vortec 3500 decreased the scale right down to solely 5, with a displacement of three.5 liters. It used the identical 3.7-inch cylinder bore and 4.0-inch piston stroke because the Vortec 4200, together with the identical rods, pistons, and valves.
The Vortec 3500 was utilized in GM’s compact pickups, these being the first-generation Chevrolet Colorado and GMC Canyon. Both vans had been launched for the 2004 mannequin 12 months and used the five-cylinder because the extra-cost engine possibility over the Vortec 2800 four-cylinder. The straight-five produced 220 horsepower and 225 pound-feet of torque.
Bring A Trailer
Speaking of the Vortec 2800 engine, this four-cylinder Atlas engine additionally used lots of the similar elements, together with the rods, pistons and valves. A giant cause for this was to maintain prices in examine, but additionally helped entice prospects after the success of the Atlas I-6 engine. Standard for the Chevrolet Colorado and the GMC Canyon, the Vortec 2800 would produce 175 horsepower and 185 pound-feet of torque.
Despite having a reasonably brief lifespan of solely seven years, the GM Atlas engine, notably the primary inline-six iteration, set the stage for additional improvements below the hood of numerous vehicles and vans. Despite not being as spoken about as engines reminiscent of Chevrolet’s big-block V-8s or the LS7 Crate engines, the Atlas’ contributions to the business cannot be forgotten.
The Forte is useless. Long reside the K4. Kia will exchange the compact sedan with a brand new automobile scheduled to debut on March 27 on the New York Auto Show. Kia will present the ultimate design every week from immediately, however within the meantime these teaser photographs must make do.
The 2025 Kia K4 already seems so much totally different than the outgoing mannequin. It shares some styling cues with the K3 launched in August 2023, however that automobile is not coming to the United States. We are getting the brand new K4, full with droopy lights harking back to a Cadillac. We’ve tweaked the publicity and brightness of the official photographs to unlock extra design particulars of Kia’s Corolla fighter.
