The Tesla Model Y SUV
Tesla Inc. (formerly Tesla Motors Inc.) is a US based electric vehicle (EV) manufacturer with the following portfolio of electric vehicles:
- All-electric Tesla Model X
- All-electric Tesla Model S
- All-electric Tesla Model Y
- All-electric Tesla Model 3
- All-electric Tesla Roadster
- All-electric Tesla Cybertruck
The Model Y is a Tesla Model 3 based crossover with inspiration also taken from the Tesla Model X SUV. However the Model Y does not have the iconic ‘falcon wing doors’ used in the Model X. The Model Y has been developed to further increase the ‘mass market appeal’ of Tesla pure electric cars.
A strategy very similar to the successful Tesla Model 3. However, unlike the Model 3, the Model Y has room for up to seven adults with an optional third row. The extra seats are an additional cost. Tesla commenced Model Y deliveries for the US market in early 2020 (6 months ahead of schedule).
The Tesla Model Y electric SUV is available in three variants: the entry-level Tesla Model Y, the Model Y Long Range and the Model Y Performance. The entry-level is a rear-wheel drive (RWD), while the other two are offered as dual motor all-wheel drive (AWD).
In terms of pure electric range, neither of the variants disappoint. The entry-level variant has a claimed zero-emission electric range up to 430 km (WLTP), while the Long Range has a range up to 533 km (WLTP). The top of the line, Model Y Performance has an e-range up to 514 km (WLTP).
Even adjusting for real-world driving conditions, the range for the Model Y is impressive. For the entry level, expect a real-world electric range closer to 390 km. For the Long Range, a pure electric range up to 480 km is more realistic.
For the Performance, expect an electric range closer to 460 km. For those new to electric driving, a number of factors impact the EV range. Some of these include: road conditions, speed, weather, payload, passenger load, tyre size, driving profile and more!
Tesla owners benefit from the Tesla Supercharger network. In fact, Tesla owns and operates the largest fast charging network globally (35,000+ globally) and the network continue to expand rapidly. Tesla claims that Superchargers can add up to 270 km of electric range in just 15 minutes. The Superchargers offers a maximum DC charging rate up to 250 kW. For single-phase (7.4 kW) EV charging at home, the EV will take up to to 12 hours to fully charge.
We at e-zoomed encourage using a dedicated single-phase residential EV charger like myenergi zappi for charging at home. Though electric cars can be charged via a domestic 3-PIN plug, we at e-zoomed do not encourage using a domestic plug for charging an electric car.
In terms of performance, the entry-level rear-wheel drive Model Y can achieve 0-100 km/h in 6.9 seconds, with a top speed up to 217 km/h. The all-wheel drive Tesla Model Y Long Range can achieve 0-100 km/h in 5 seconds, with a top speed up to 217 km/h. The top of the line, Tesla Model Y Performance can achieve 0-100 km/h in 3.7 seconds, with a top speed up to 250 km/h. Of course, the Tesla electric car also benefits from instant torque.
The interior of the electric car is designed for minimalism and space. The EV includes a 15 inch touchscreen display and a number of advanced features, either available as standard or an additional option. Some of these include: all-glass roof, 360 degrees rear, side and forward-facing cameras, Tesla Vision (detects nearby cars, helps prevent potential collisions and assists with parking), Tesla Autopilot, summon, smart summon, auto park, auto lane change and more.
The EV is practical. The boot size is 854 L. The electric car also has a ‘frunk’ under the bonnet (117 L). Bottom-line, electric driving is good for the environment and the wallet! The Tesla Model Y electric SUV is not available in India.

Overview: Types Of Electric Vehicles (EVs)
“Electric vehicle” is an umbrella term, and a broad one at that. There are a number of different types of electric vehicles (EVs), each with its distinct characteristics and advantages. These include:
- BEVs: Battery-electric vehicles (pure electric)
- PHEVs: Plug-in hybrid electric vehicles (electric and internal combustion engine (ICE) combined)
- MHEVs: Mild hybrid electric vehicles (internal combustion engine (gasoline or diesel) along with regenerative braking)
- FCEVs: Fuel cell electric vehicle (electric with hydrogen as fuel)
The above “types” are powered either entirely or partially by electric energy and have different environmental impacts.
Battery-Electric Vehicles (BEVs)
Battery-electric vehicles (BEVs), also known as pure electric vehicles, are powered entirely by electricity (i.e. the vehicle does not have a conventional internal combustion engine). BEVs have zero-tailpipe emissions and help improve local air quality.
BEVs are also very economical to drive. A BEV can cost as little as Rs 50 per 100 kilometres to drive. Examples of best-selling EVs include, the all-electric Tesla Model 3 and the all-electric Renault Zoe. A BEV is charged by plugging in the electric vehicle to a dedicated electric car charging station (home or public charging stations). BEVs are well suited for those living in towns, cities and urban centres. Of course, battery-electric vehicles are also suitable for those living in rural settings.
Plug-In Hybrid Electric Vehicles (PHEVs)
Plug-in hybrid electric vehicles (PHEVs) differ from battery-electric vehicles (BEVs), in that, PHEVs use both a conventional internal combustion engine (ICE) and an electric engine for propulsion. Plug-in hybrid vehicles combine the advantages of electric driving and internal combustion engine driving.
On shorter distances, the PHEV uses the electric mode to drive emission-free, using the on-board EV battery and regenerative braking. For longer distances, the plug-in hybrid electric vehicles switches to using the internal combustion engine.
With a PHEV, the vehicle can cost as little Rs 50 per 100 kilometres to drive on e-mode, without any tailpipe pollution, and also be driven long-distances, without the fear of range anxiety! Most PHEVs have an EV battery of up to 15 kWh and can achieve a zero-emission electric range of up to 50 kilometres.
No wonder PHEVs are fast becoming popular globally, with much potential or India. Like a BEV, the plug-in hybrid electric vehicle is charged by using an external power source (EV charging point) for charging.
PHEVs are suitable for those that drive long-distances on a regular basis but want to lower the negative environmental impact from tailpipe pollution. PHEVs are also suitable for those individuals and families that are seeking to save money by taking advantage of electric driving. The Volvo XC40 PHEV and the Volkswagen Golf 8 are good examples of PHEVs.
Mild Hybrid Electric Vehicles (MHEVs)
Mild hybrid electric vehicles (MHEVs) are a limited form of electric driving. These vehicles also use hybrid technologies (electric driving and internal combustion engine), but the EV battery is much smaller than a BEV or PHEV.
Moreover, in a mild hybrid, the EV battery cannot be charged via an external source (i.e. EV charging station). In a MHEV, the battery is charged by capturing the energy released during braking, a process known as regenerative braking. MHEVs have lower tailpipe emissions, and are more economical to own, run and maintain than petrol and diesel cars.
MHEVs are a better option than a petrol or diesel car, but not as good an option as a BEV or PHEV. Mild hybrids are well suited for those living in regions with limited charging infrastructure. Again, MHEVs have great potential in India, given the limited public EV charging infrastructure.
The Toyota Prius is a good example of a mild hybrid electric vehicle.
Fuel Cell Electric Vehicles (FCEVs)
Fuel Cell Electric Vehicles (FCEVs) also called hydrogen fuel cell vehicles, have a fuel cell stack that uses hydrogen to generate the electricity needed to power the electric vehicle. The fuel cell generates electricity and pure water vapour that can escape via the tailpipe.
It is capable of generating electricity as long as there is a steady supply of hydrogen. Fuel cell electric vehicles can be refuelled with hydrogen at purpose built filling stations. Filling an FEC takes no more than five minutes.
FCEVs have a range of about 500 kilometers or more between refueling. Today, the only and major limitation is the very limited hydrogen refuelling station network globally. The Toyota Mirai FCEV is a good example of this type of EV.
