The Porsche Panamera Plug-In Hybrid
Stuttgart based Porsche is known for high-performance cars and is currently owned by the Volkswagen Group. Porsche has always had a close relationship with the Volkswagen Group, because the iconic VW Beetle was designed by Ferdinand Porsche, the founder of Porsche. Apart from this, both VW and Porsche have collaborated on a number of platforms, to include, the Porsche Cayenne SUV. Porsche currently has the following electric vehicles (EVs) in its portfolio:
The Porsche Panamera luxury hatchback was unveiled in 2009 at the Auto Shanghai International Automobile Show. Production began the same year in Germany and the Panamera continues to be manufactured in the country. The hybrid variant was launched in 2011 and the plug-in hybrid variant released in 2013. The PHEV was unveiled at the 2013 Shanghai Auto Show.
As one can expect, a Porsche never disappoints when it comes to quality and performance. The Panamera PHEV is no different. Given the instant torque from an electric engine, the plug-in electric car achieves 0-62 mph in 4.4 seconds for the entry level variant. The top level variant, the Turbo S E Hybrid Sport Turismo, achieves 0-62 mph in 3.2 seconds, with a top speed of 196 mph. But of course, luxury and performance from this famed marquee does not come cheap.
The electric vehicle (EV) is without an iota of doubt, stunning in design, style, quality and performance. But it has its limitations in terms of interior space, to include the limited headroom for rear seat passengers. The plug-in electric vehicle (PHEV) is perfect for those drivers that want the performance and quality of a Porsche, but with better environmental credentials (tailpipe emissions: up to 57g/km). Though the PHEV has a zero-emission electric range up to 35 miles, based on driving style and driving conditions, the real world range could be closer to 25 miles.

Benefits Of Electric Driving
The benefits of electric driving are many, with significant advantageous over petrol and diesel internal combustion (ICE) engine cars, for all stakeholders. These benefits include:
- Lower to zero-tailpipe emissions
- Lower running costs
- Lower taxes
- Lower maintenance costs
- Lower noise pollution
- Convenience of charging at home
- Smoother drive
- Instant torque for acceleration
- Lower environmental impact
Below we have highlighted three of our favourite benefits of owning and driving an electric car.
Improved Air Quality
Battery-electric vehicles (BEVs) or all-electric vehicles do not have tailpipe pollution. In fact, such electric cars do not even have a tailpipe! Zero-emission electric driving has a real and immediate impact on local air quality i.e. improving air quality. While, plug-in hybrid electric vehicles (PHEVs) have reduced tailpipe pollution compared to traditional petrol and diesel vehicles. The sooner we migrate to electric driving in India, the sooner we can improve air quality for all our cities, towns and villages. Lower air pollution will also result in a reduced number of health issues arising from inhaling toxic pollutants.
Lower Maintenance & Running Costs
Electric vehicles (EVs) are cheaper to maintain and drive. Pure electric cars have far fewer moving parts compared to internal combustion engine (ICE) vehicles. The fewer the moving parts, the lower the probability of repair and maintenance. Moreover charging an electric car can cost as little Rs 50 per 100 kilometres! A full charge can cost between Rs 100 and Rs 200. Significantly cheaper than filling a tank of petrol or diesel!
Lower Noise Pollution
Yes, we in India are far more resilient to noise pollution than those living in the western world. We have certainly got used to horns blaring and engines roaring, day and night. But that does not mean we enjoy or welcome noise pollution. In fact, quite the opposite!
Though much focus has been on the advantageous of ‘air quality’ with an electric car, just as important, is the benefit of lower noise pollution. In fact, pure electric cars are silent, with an inbuilt ‘sound booster’ to increase road safety for pedestrians. As our cities in India and across the world become densely populated with cars, the significant negative impact on ‘quality of life’ as a result of increased noise pollution from petrol and diesel vehicles, is just as dangerous, as increased air pollution. Battery-electric cars are a perfect solution in reducing noise pollution and increasing the living standards for us all. Of course, one can only hope that the self inflicted ‘horn blaring’ pollution will also reduce!
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.
