Summer travel on the Pune–Mumbai corridor has a reputation. Afternoon haze over the Expressway, packed holiday traffic on long weekends, and the unmistakable feeling of stepping into a cab that has been sitting in the sun. For three to three-and-a-half hours, that is a long time to be uncomfortable.
Orbitmiles EV cabs are genuinely different in summer — and not just because of the air conditioning. Here is what makes the difference, and how to make the most of your warm-weather journey on this route.
Why EV Cabins Feel Cooler in Summer
The most immediate difference between an EV and a petrol or CNG cab in summer is heat generation. A petrol engine produces enormous amounts of waste heat — from the engine bay, the exhaust system, and the transmission tunnel running through the centre of the cabin. That residual heat radiates into the passenger compartment even with the air conditioning on, working against the AC system throughout the journey.
Electric motors generate a fraction of this waste heat. There is no exhaust pipe running under the cabin, no hot engine bay directly in front of the firewall, and no transmission tunnel warming the floor. This means the AC in an Orbitmiles EV is fighting much less ambient heat — and the result is a cabin that genuinely reaches and holds a comfortable temperature faster, and maintains it more efficiently throughout the journey.
Does Running AC Affect EV Range?
This is a fair question — and the honest answer is yes, AC usage draws from the battery. In real-world conditions, sustained AC use on a highway journey reduces the vehicle's effective range by roughly 10–15% compared to mild-weather driving without AC.
For the Pune–Mumbai route, this is not a concern. The MG ZS EV and Kia Clavis EV in the Orbitmiles fleet have a real-world highway range of 300–350 km. Even with AC running at full power throughout a 180 km journey, both vehicles arrive in Mumbai with more than 100 km of range remaining. The AC stays on for the full trip.
Orbitmiles checks every vehicle's state of charge before departure. If a vehicle's battery is not fully charged before a summer trip, a replacement is deployed. The AC is never turned off to preserve range — that is simply not how we operate.
Summer Travel Tips: Making the Most of Your Journey
Even in a well-cooled cabin, a few small adjustments to how you plan your summer trip make a noticeable difference:
6–8 AM or after 7 PM are the coolest, least congested windows on the Expressway.
Even in AC, staying hydrated over a 3-hour journey improves comfort significantly.
Light cotton or linen clothing makes the temperature contrast between outdoors and the cabin far more comfortable.
All Orbitmiles vehicles have tinted windows. Ask your driver for rear window sunshades if available for your vehicle.
Screens generate heat. If you are prone to motion sickness or headaches in warm weather, take breaks from devices during the journey.
For longer summer trips, ice packs around perishables in the boot help protect anything temperature-sensitive.
Timing Your Summer Journey
Summer traffic on the Pune–Mumbai Expressway follows a predictable pattern. Early morning slots — departing Pune between 6 and 8 AM — are consistently the smoothest. Temperatures are lower, the road is quieter, and you arrive in Mumbai before the worst of the afternoon heat sets in. For a 10 AM Mumbai meeting, a 6:30 AM Pune pickup is the standard recommendation.
Midday travel between noon and 3 PM is the least comfortable window in summer — not because of the cab itself, but because of the expressway conditions: peak road temperature, maximum solar glare, and the highest likelihood of holiday traffic on weekends and long weekends. When you have the flexibility to choose, early morning or post-7 PM departures are the smarter choice in the April–June window.
If a midday departure is unavoidable, Orbitmiles drivers are experienced with summer expressway conditions. The route stays on the Mumbai–Pune Expressway throughout, which has better shade cover and service areas than the alternative NH-48 route. A short refreshment break at one of the expressway's service areas is a welcome addition on longer summer trips.
Travelling with Children or Senior Passengers in Summer
Summer travel with kids or elderly family members requires a little extra thought. Children are more sensitive to temperature fluctuations — the transition from a 38°C pavement to a 20°C cabin and back again is harder on small bodies. Dress children in layers you can remove quickly once inside the vehicle.
For senior passengers, direct AC airflow on the neck or arms for three-plus hours can cause discomfort. Orbitmiles vehicles have adjustable vents — ask the driver to direct airflow towards the cabin ceiling rather than horizontally, which circulates cool air without the blast effect. A light shawl or jacket for the journey is a sensible addition even in peak summer.
The En-Route Refresh Break
Every Orbitmiles journey includes a standard 10–15 minute refreshment break en route, typically around the Khopoli or Lonavala area. In summer, this break is especially useful — passengers can stretch, use facilities, grab water or a cold drink, and return to a freshly cooled vehicle for the second half of the journey.
If you would prefer to skip the break and continue straight through, simply let your driver know at the start of the trip. For passengers who would prefer two shorter stops rather than one, that can also be arranged. The journey is yours.
Frequently Asked Questions
Does running AC in an EV cab significantly reduce battery range?
Yes, AC usage draws from the battery, but modern EVs account for this in their real-world range figures. On the Pune–Mumbai route, even with AC running throughout, Orbitmiles EVs complete the trip comfortably on a single charge with well over 100 km of range remaining on arrival.
What is the best time to travel Pune to Mumbai in summer?
Early morning (6–8 AM) is the coolest and least congested time. Late evening (after 7 PM) is the second-best window. Midday travel between 12–3 PM should be avoided when possible — both for comfort and because expressway traffic tends to peak during those hours on weekends.
Are Orbitmiles EVs good in Indian summer heat?
Yes. All Orbitmiles vehicles have strong cabin AC systems rated for Indian summer conditions. EV batteries also include thermal management systems that keep the powertrain operating efficiently regardless of ambient temperature. The AC runs throughout the journey without compromise.
Can I ask the driver to adjust the AC temperature during the trip?
Absolutely. Orbitmiles drivers are trained to accommodate passenger comfort preferences. Simply ask, and the driver will adjust the temperature or airflow direction to suit you. Most vehicles also have rear-seat AC vents for independent airflow control.
Should I carry water for a summer Pune to Mumbai cab journey?
It is always a good idea. Staying hydrated over a 3+ hour journey improves comfort noticeably, even in an air-conditioned cab. Orbitmiles drivers include a short refreshment break en route where you can stretch and grab cold drinks if needed.
