The Honda Metropolis e:HEV hybrid comes with a popularity for sophistication and sterling gasoline effectivity. Its distinctive Atkinson Cycle 1.5-litre four-cylinder engine is mated to 2 electrical motors – the primary one acts as an electrical generator, whereas the second handles propulsion duties.

Honda Metropolis e:HEV, with a tank capability of 40 litres, claims a gasoline economic system determine of 26.5kpl and 1,000km of vary. These figures set us fascinated by hypermiling the Metropolis e:HEV – how far can it go on a single tank of gasoline? Is Bengaluru to Mumbai doable? That’s precisely what we got down to discover late final month, as we pointed the sleek nostril of the Honda in direction of Mumbai from Bengaluru. This was not a take a look at designed for the actual world, however extra of a mission to stretch the vary of a hybrid to the extent attainable after which attempt to take it additional.

Honda Metropolis e:HEV: complicated powertrain

Earlier than we get on with the journey, let’s take a fast take a look at the Metropolis’s hybrid powertrain that’s each fascinating and sophisticated – it includes an engine, electrical motors and a lithium-ion battery pack. The engine produces 126hp of energy and 253Nm of torque, and the powertrain is mated to an e-CVT.

The Metropolis hybrid’s self-charging mechanism and electronics work in tandem to make sure that the battery pack by no means depletes totally, and normally, the automobile wakes up in pure EV mode, because it did in Bengaluru in early August. The odo began ticking as we minimize via early morning visitors within the metropolis, and inside an hour of departing from the Vidhana Soudha, we have been on the Golden Quadrilateral Freeway that results in Mumbai.

You gained’t discover something too totally different whereas driving the Metropolis hybrid, besides, in fact, that the automobile involves life silently. As speeds enhance, the Hybrid mode will get activated, which sees energy despatched to the wheels by each the engine and electrical motor. When the battery is operating low on cost, the engine additionally juices it up. The hybrid system robotically shuffles between the total EV mode, the hybrid mode and the engine mode; and the system selects the mode by contemplating varied elements, together with battery cost degree, throttle place, angle of the highway and highway pace.

Honda Metropolis e:HEV: hypermiling on the Golden Quadrilateral

Our technique was to attempt to ‘stay’ within the EV mode so far as attainable, since that’s the one method one can save gasoline. It was, in fact, simpler stated than carried out, as a result of the automobile intelligently switches between modes by itself. We caught to the 50kph-60kph band for a majority of the time we have been on the highway, guaranteeing that momentum was not misplaced. After all, wherever the terrain was beneficial by way of elevation, the e:HEV cruised at triple-digit speeds.

The automobile effortlessly toggled between the modes and the numbers that appeared on the instrument cluster have been astonishing – all the time over 30kpl on the highways. The Metropolis’s instrument cluster has an informative vitality move meter that shows the supply of energy that’s propelling the automobile – both the battery motor or the petrol engine, or from the hybrid system mixed – and it motivates one to drive as effectively as attainable.

Hypermiling requires a sedate foot and many restraint and focus. You’ll want to be within the zone otherwise to have the ability to hold making incremental progress, shutting out the voice in your head that desires you to flooring the pedal. There are a number of vital classes you study as you go alongside: acceleration needs to be as linear as attainable; anticipating oncoming visitors and highway situations is essential; and being properly rested is the third.

We might have simply carried out Bengaluru-Mumbai in a day however hypermiling is demanding, so we broke the journey in Belagavi. A particular point out right here for the Metropolis e:HEV’s throne-like driver’s seat and tech-studded cabin, which made our run snug.

And so we motored alongside, with cities whipping previous us on the Golden Quadrilateral, casting glances on the informative vitality move meter. The Metropolis e:HEV’s motor braking may be very progressive and well-calibrated. Drivers can select between three ranges of depth that may be managed by the steering-mounted paddle-shifters, and we switched – by way of the gear lever – to ‘B’, or Braking Mode, on downhill stretches for a good stronger regen to recharge the battery.

The Metropolis e:HEV additionally has a bunch of ADAS options, however utilizing one thing like adaptive cruise management would have been self-defeating, as cruise management, whereas protecting a gentle tempo, shouldn’t be very best for hypermiling. For example, it doesn’t ‘see’ visitors up forward of time and thus carries powering the automobile, whereas a driver would carry off and coast. 

Honda Metropolis e:HEV: the outcomes

Quickly, we have been on the expressway that results in Mumbai. The vary proven on the instrument cluster was 439km; driving with excessive restraint on the extensive, open roads was not very simple, however we gamely held on. We bought into Mumbai in direction of night and the visitors affected the Metropolis’s general common pace. Lastly, at 8.45pm, the Metropolis e:HEV rolled into the IOC gasoline station at Bandra. We had made it from Bengaluru to Mumbai on a single tank!

We tanked up the automobile to learn how the Metropolis e:HEV had carried out on the drive from Bengaluru to Mumbai. And, the numbers have been spectacular, even when, in a method, anticipated. The Metropolis e:HEV coated 1,006km and consumed 29.08 litres of petrol. Its gasoline economic system? A stupendous 34.59kpl. Take a bow, Honda Metropolis e:HEV.
