The East Coast Highway, which connects Chennai with Pondicherry, is considered one of our favorite stretches. With an awesome view of the ocean, sparse site visitors and easy tarmac, it’s an instantaneous mood-lifter. Final month, we discovered ourselves on this very street but once more. This time, although, other than submitting ourselves to the pleasures of the open street, we have been additionally trying out Apollo’s Amperion, one of many nation’s first-ever tyres particularly made for electrical autos.

The Amperion makes use of the newest gen polymers and traction resin for low rolling resistance and, consequently, higher vary.

So, sure, it goes with out saying that we have been in an EV ourselves, and a formidable one at that – the Tata Nexon EV Max – shod with Apollo Amperion. Maintain on, why would EVs want tyres specifically made for them, and the way are they totally different from common tyres?

Electrical autos provide a bunch of many apparent advantages, however there may be additionally one other facet to the image, particularly within the context of tyres. EVs are considerably heavier than ICE autos, due primarily to the load of the battery packs, and that instantaneous torque, which lovers hold raving about, results in greater tyre put on. Whereas EV tyres may look much like tyres utilized by ICE autos, they’re markedly totally different in terms of tyre design, elements used and building.

The Amperion’s improved tread sample and rubber compounds assist it handle an EV’s instantaneous acceleration.

The Apollo Amperion, for example, makes use of the latest-generation polymers, traction resin, and different uncooked supplies. And, to handle the moment acceleration of EVs, the Amperion additionally has an improved tread sample and rubber compounds. The Amperion vary, out there in 195mm and 215mm tread sizes, in each R16 and R17 rim profiles, utilises high-traction, full-silica rubber for its tread compound.

The Amperion, whose design takes inspiration from jellyfish, is taken into account to be among the many most power environment friendly and silent creatures, additionally reveals lesser rolling resistance, amounting to round 30 p.c. This consequently improves the efficiency of the EV and extends its battery vary. Apollo calls the ultra-low rolling resistance expertise bundle BEST Tech (Battery Vitality Saver Expertise).

One other attribute that helps the Amperion obtain diminished resistance on the street is its recessed profile, which helps decrease aerodynamic drag. The Amperion is not only among the many first EV-specific tyres to be launched in India, it is usually the primary EV vary of tyres to obtain a 5-star ranking for all of the launched sizes by the Bureau of Vitality Effectivity.

The Apollo Amperion accentuates an EV’s trademark enjoyable drive.

Electrical autos such because the Tata Nexon provide quiet, enjoyable drives, and tyres such because the Amperion enhance on the expertise. The Amperion is supplied with AQuT Tech (Apollo Quiet Tyre Expertise), which works on tyre cavity, tread sample and building to cut back noise. The tread sample on the Amperion is stiffer and has a bigger footprint with a number of pitch sequences to attain the specified necessities of low noise, apart from serving to obtain low-rolling resistance and excessive traction.

In ICE autos, tyre noise is subsumed by the roar of the engine, however in an EV, the previous could be very noticeable and Apollo has accomplished a commendable job in elevating the serenity inside EVs. However the trick up the Amperion’s sleeve just isn’t restricted to only low noise – in keeping with Apollo, Amperion tyres are able to enhancing the vary of EVs by as much as eight p.c. Which is, in fact, what acquired us curious within the first place and led to this drive we’re on.

To chop an extended, nice story brief, the Amperion tyres made the ECR drive a memorable expertise. Our plan was to go to Pondicherry and again on a single cost after which tally the figures with our earlier exams with the Nexon EV Max. (The Nexon EV Max had achieved 263km again in June.) We caught to Metropolis and Eco modes throughout our run, and after a fast lunch in Pondicherry, we headed again up the ECR, keeping track of the odo on a regular basis. The ultimate numbers have been fairly spectacular. The Nexon EV Max achieved a variety of 280km, which was about 5 p.c greater than our earlier real-world take a look at determine of 263km. Clearly, it pays to suppose in another way in terms of EV tyres, and Apollo has proven it additionally pays dividends.

Hitesh Joshi, head of R&D at Apollo Tyres, on how the Amperion enhances the EV expertise.

What are the salient options of the Apollo Amperion?

The Apollo Amperion tyres are particularly designed for electrical autos, which have totally different efficiency necessities than common ICE autos. EV tyres have to satisfy particular expectations that need to do with vary, traction, in addition to robustness and sturdiness due to the distinction in weight between an EV and ICE car.

What are the foremost variations between a daily tyre and a tyre particularly made for EVs, such because the Amperion?

The most important expectation is the battery vary. The tyres have been designed with best-in-class rolling resistance particularly for EV autos and clients can count on the tyres to increase the battery vary by a minimal of 5 p.c. We now have additionally taken into consideration the additional traction requirement, because the motor torque is sort of excessive in EVs, and in addition the truth that they weigh greater than ICE autos. So, it helps EVs brake on the proper distance, making certain that regenerative braking additionally comes into play seamlessly. The tyres’ load-bearing capabilities are additionally prime notch and we now have designed them holding Indian situations in thoughts.

By way of building, how is the Amperion totally different?

We’re utilizing a particular expertise of full-silica tread to make sure that we get the proper traction and proper rolling resistance. Aside from the total silica tread, we additionally use fourth-generation polymer expertise and functionalised resins, which impart excessive traction to the tyre, other than different properties. So, that is the important thing distinction on this fashion. Coming proper again to the development, we additionally strengthened the tyre for Indian street situations and to make sure the specified traction and dealing with are offered.

How does the Amperion assist prolong battery vary?

Once we designed the Amperion, we labored so much on getting the supplies expertise and design bang on. The design of the cavity of the tyre helps it ship a lot better aerodynamic drag power. And that helps in decreasing the general rolling resistance.
