SEAT unveils plug-in hybrid prototype based on the new Leon hatchback; smart charging and V2G

SEAT, a Spanish motor company and member of the Volkswagen Group, has unveiled a plug-in hybrid R&D prototype based on the new Leon hatchback. The Leon Verde (“Green”) prototype is the culmination of the four-year Cenit Verde research project in Spain, and was presented at the official closing event of the project.

The plug-in hybrid combines a 120 hp (90 kw) 1.4 TSI gasoline engine with a 75 kW electric motor. Combined maximum output is 125 kW. Combined cycle fuel consumption is estimated at 1.6 l/100 km (147 mpg US), with 36 g/km CO2; all-electric range is 31 miles (50 km). With a fully charged battery and a full 40-liter (10.6 gallons US) gasoline tank, its total range is 507 miles (816 km).

The Leon Verde is equipped with an advanced Human-Machine Interface (HMI) integrated into a smartphone app. This enables the driver to connect to the car via a wireless network with his or her smartphone to manage functions such as energy consumption, battery status, recharge management, and estimated CO2 savings in electric mode; two patents were applied for during the creation of the HMI alone.

In addition, the project has enabled development of a Driving Cycle Predictor, which analyses and memorizes the routines and driving style of the driver, using this information to optimise energy consumption and reduce CO2 emissions. SEAT has taken out a patent for this technology, too.

The holistic approach to electric vehicle development undertaken by the Cenit Verde project resulted not only in the new vehicle, but a new approach to charging infrastructure as well.

In collaboration with companies including Cobra, Endesa, Iberdrola and Red Eléctrica Espana, a system of tariff negotiation and smart energy management has been developed, which effectively allows the car to interact with the electricity grid.

The system detects when overall energy consumption is low on the grid, and incentivises, by way of lower costs, charging during these times. If the car is left plugged into a power source between 7pm and 7am, for example, the system will only charge the car at times when it detects the overall demand has dropped, using a recharge manager.

The user can specify whether he or she wishes the system to work this way, paying less for energy consumed when demand is low. Alternatively, a standard quick charge function is also available.

Via a Lear 20 kW on-board charger, the Leon Verde also allows for two-way connection to the grid, allowing it to feed in electricity.

The SEAT Leon Verde prototype is a research and development vehicle, and the result of the collaborative Cenit Verde research project. There are no plans to put the car into series production.



"Combined cycle fuel consumption is estimated at 1.6 l/100 km (147 mpg US), with 36 g/km CO2;"..

"There are no plans to put the car into series production."??


"MPGe" numbers such as "combined cycle fuel consumption is estimated at 1.6 l/100 km (147 mpg US)" are always fraudulent. The number does not account for the energy losses nor the CO2 emission of the electrical power generation.


The number does not account for ___ the CO2 emission of the electrical power generation.

Nor should it when the makeup of the electrical power generation is so variable with each region it might be charged in. Energy losses and the CO2 emissions are meaningless if you're using your EV to store excess wind or solar power.


This car doesn't get 147 mpg. It gets 31 miles petrol-free, and then works similar to a standard Prius, or slightly better, because it can accelerate up to freeway speeds in all electric mode, so probably closer to 70 mpg. It would do the industry better not to stretch the claims for plugins. Maybe they should publish two sets of with no starting charge and one with a fully charged battery.

Something like this maybe?


Here is a good video for an wAWD super car. It "only" costs $980,000 :)

Nice one! But they're making only 88 of them.

On the other end of the scale;
The C-1 uses a 8kwh pack but has a 200mile range, a 100+mph top speed and does 0-60 in 6sec. Plus it seats two.

Slightly bigger is the MonoTracer;

Assuming 12.000 mi. per annum averages to 33 mi. per day. The electric range of 31 mi. covers almost completely the average daily distance. Sounds viable.

Drivers have different needs. Some people drive few miles per day and have access to another car with long range or generally don't drive long distances.

A limited electric range EV or PHEV can suit them fine and save them purchase money.

We make a range of ICEVs from motorbikes to 18 wheelers. People generally buy the least expensive ride that fills their needs.


The guy says I don't drive far, so I will pay $40,000 for a Ford EV that only goes 70 miles.

I don't think so, the bloggers say "what is the resale?". If it only goes 70 miles, how far in 6 years and how much will it sell for with a worn battery pack?


SJC makes a good point, but is overthinking it. My 91 year old mother bought a cheap clunker that gets 9 miles to the gallon, on a good day. She says she couldn't care less about the price of gas because she doesn't drive more than 20 miles a week.
If I only drove 5 miles a day, I would buy the cheapest car on the road and not worry about fuel cost.



You are exactly right. Anybody who only drives 30 miles a day doesn't need an electric car. They can drive any old jalopy and still spend less on gas than they do on coffee.
