Finally, one of the reasons that hybridizing gasoline engines is successful is that they are inherently less fuel efficient.
Gasoline engines only convert 25 to 30% of a fuel’s energy into forward motion at the wheels; the rest is squandered as heat and noise.
A diesel, on the other hand, transforms 30 to 35 percent of the energy in the fuel into forward motion, resulting in higher fuel efficiency ratings.
In the end, say diesel engineers, a diesel hybrid would add a very expensive electrified system to an already-expensive engine… but the overall rise would be less impressive than in gasoline automobiles.
But, you say, three diesel hybrids are already on the market in Europe!
That is correct. Only one of them, the Mercedes-Benz E 300 BlueTEC Hybrid, combines a diesel engine and an electric motor into a single powertrain.
The Peugeot 3008 HYbrid4 and the Citroen DS5 Hybrid, on the other hand, are “through-the-road hybrids,” meaning they have a single motor on both ends.
They can use the electric motor alone for lower-speed excursions, the diesel engine for higher-speed travels, or the two together for the best performance driving by distributing power to all four wheels.
Mercedes-Benz, which has sold diesels in the United States for decades, has no intentions to sell the world’s only diesel-electric hybrid powertrain in the United States.
Meanwhile, we’d like to hear from engine and powertrain engineers on these topics.
Why aren’t there any diesel-electric hybrid automobiles on the market?
The car would almost certainly have greater fuel economy and more power. It would also be significantly more long-lasting. The world’s first hybrid car, however, was designed to arrive “before” the future.
With Tesla entering the market and drastically altering the EV market, Toyota and many other automakers have forced to reconsider their plans for the future of transportation.
Toyota will continue to use hybrid technology as long as they are able. They’re also pushing hard for HFCV (hydrogen fuel cell vehicle), which is currently only available in a few locations of the country.
Hybrids will become obsolete rapidly if Toyota is unable to either make the electric vehicle market work for them or mass-produce hydrogen in a cost-effective and ecologically friendly manner. A hybrid diesel, no matter how you slice it, will never happen.
Diesel exhaust fluid (DEF) is a liquid that is pumped into diesel engines to help them burn more efficiently. A well-running diesel with a DEF system emits much fewer emissions from the tailpipe than a gasoline vehicle.
The disadvantage is that incorporating a diesel DEF system into a hybrid adds weight and money, which is not why hybrids were created in the first place.
If the base price of a Toyota Prius increased from $25,000 to $35,000, it would take considerably longer to recoup your fuel savings from driving. When you factor in the cost of DEF and diesel exhaust regen maintenance, you’ve got a big dilemma on your hands.
The additional cost of these measures would make having a diesel in a hybrid car unprofitable. It would be great if we didn’t have to deal with all of the regulations, but we are where we are, and there is nothing we can do about it.

Will electric vehicles eventually supplant diesel vehicles?
Did you realize that driving can be environmentally friendly? Electric vehicles are healthier for both you and the environment because they release fewer greenhouse gases and do not pollute the air. So why not go electric instead of diesel or gasoline?
There are a variety of reasons to change your driving style, but let’s start with the facts.
FALSE. According to recent research, electric cars and vans will be cheaper to manufacture in Europe than gasoline and diesel vehicles by 2027 at the earliest. This is due to dropping battery costs and automakers developing electric vehicle production lines.
Over the last decade, the price of batteries has dropped by 89 percent since 2010! Consumers are taking notice: global sales of electric vehicles increased by 43% in 2020.
Furthermore, because electric automobiles have fewer moving parts than traditional engines, they can have reduced maintenance expenses. Other costs vary depending on where you live, but you may usually save money on gas and take advantage of tax incentives. Electric vehicles are tax-free in Belgium, Greece, Hungary, the Netherlands, Latvia, and Portugal, among other countries. Norway, Germany, France, Italy, Spain, and Sweden, for example, provide free parking for electric vehicles.
According to a recent survey, more than 90% of electric car owners claimed they would not switch to a gasoline or diesel vehicle.
FALSE. Most individuals drive less than 40 kilometers per day, which is far less than the 200 to 490 kilometers that today’s electric cars can travel. When you go home, plug your car in and charge it overnight so it’s ready to go the next day.
If you’re planning a lengthy vacation, there’s no need to leave your electric car at home because the network of public chargers is fast expanding – they’re easy to find using the European Alternative Fuel Observatory’s charging point map, as well as other maps such as Open Charge and PlugShare. Over 200 000 public charging points have been installed across the EU by the end of 2020, with the EU aiming to deploy 3 million by 2030.
The first battery capable of charging a 320 km electric car in 5 minutes was released in early 2021, making it feasible to charge your electric automobile in nearly the same time it takes to fill up a full tank of gasoline or diesel.
“‘Range anxiety,’ or the dread of running out of battery power, is probably more prevalent among individuals who are still considering buying an electric vehicle than among current electric vehicle users,” says Gonalo Castelo Branco, Director of Smart Mobility at EDP, a Portuguese energy provider. EDP has pledged to cut emissions and set renewable energy targets as part of the Climate Pact. “Once you own an electric vehicle, you can easily adapt to new habits, such as charging your battery while the car is parked at home or at work.”
FALSE. Electric cars emit roughly three times less CO2 during their lifetime in Europe than petrol or diesel equivalents. Why aren’t they all the way down? Because we still rely on fossil fuels to generate electricity and charge the batteries but this is about to change. Renewable energy sources such as wind and solar are increasingly being integrated into electrical systems in various European countries. In Sweden, they account for 56.4 percent of total energy, 43% in Finland, and 41% in Latvia. In 2019, wind and solar power generated more electricity in the EU than coal for the first time.
Furthermore, this tendency is expected to continue: the EU wants to produce 40% of all energy across its territory from renewable sources by 2030.
During the manufacturing process, electric cars emit some emissions, primarily from the fabrication of batteries. However, it is projected that some models will save more carbon than it took to produce them in less than two years of driving.
What about pollution in the air? Fully electric vehicles do not produce any since they do not emit the nitrogen oxides, particle pollution, or carbon monoxide that are produced as a by-product of burning fossil fuels in a gasoline or diesel car’s exhaust pipe. Furthermore, because electric vehicles lack a traditional fossil-fuel-powered engine, they are substantially quieter, minimizing traffic-related noise pollution.
Myth 4: They’re to blame for increased natural resource mining, and their batteries pollute the environment.
FALSE. Mining of elements like cobalt, which is used in electric car batteries, has sparked controversy. True, batteries require a little amount of cobalt, but they have a lifespan of at least 10 years and may be recharged multiple times during that time. On the other hand, using a combustion engine for ten years consumes around 10,000 litres of oil, which is also extracted from the earth and seabed.
And change is on the way. The European Commission announced ideas for a battery regulation in December 2020, which would ensure that battery materials are supplied ethically and ecologically in the future.
Electric vehicle batteries can potentially have a second life. They can be recycled using new and evolving technological procedures, with up to 100% of the lithium in the battery being recovered. Repurposing the batteries is also an option. A ‘dead’ battery, while not appropriate for use in a car, will still have up to 70% of its storage capacity available, making it excellent for storing renewable energy.
FALSE. While car sales in general fell during the COVID-19 pandemic, demand for electric vehicles actually increased, accounting for 10% of all sales in Europe. In the first half of 2021, Germany recorded more electric automobiles than diesel cars.
“We’re about to undergo a big transition.” “The pandemic has put our adaptability and habits to the test, forcing us to reimagine the future of mobility,” adds Castelo Branco.
According to a recent poll, nearly two-thirds of city dwellers support prohibiting the sale of new petrol and diesel cars in Europe after 2030. The European Commission is working to make this a reality, aiming for all new automobiles registered in the EU to be carbon neutral (zero emissions) by 2035, signaling the end of the fossil fuel-powered vehicle.
The truth is that driving an electric vehicle is getting more and more convenient and economical. Not only that, but it will also assist us in achieving carbon neutrality in Europe by 2050. If you’re ready to debunk the myths, join the Climate Pact and vow to replace your gasoline or diesel vehicle with an electric vehicle.
Electric vehicles are, of course, only one part of the solution. Other ways to reduce greenhouse gas emissions and our carbon footprint include driving less, taking public transportation, and instead biking or walking. It’s often doable; all we have to do is shift our thinking and make minor alterations to our everyday routines. If a large number of people participate, it has the potential to be a game-changer not only for the planet, but also for our personal health and well-being.
Will diesel automobiles be phased out?
India, which currently has BS-IV automobiles available, will skip BS-V requirements and adopt the Euro-5-comparable BS-VI regulations straight in order to combat rising pollution and reduce hazardous exhaust emissions. As a result, many manufacturers will spend a significant amount of money developing cleaner diesel engines. Diesel cars will become much more expensive as a result of the use of expensive filters in BS-VI-compliant diesel engines and the large amount of money invested by firms, which would eventually lead to a significant reduction in demand.
What makes diesel-electric hybrids so efficient?
Although it may appear that using an indirect, two-step diesel electric energy transfer system to power your vessel is overly complicated, its numerous advantages can make it a compellingly attractive alternative to a traditional direct mechanical prop-shaft drive. When the vessel is underway, the diesel electric propulsion system may provide all of the vessel’s electrical power, eliminating the requirement for a genset.
Is there a Prius that runs on diesel?
There’s a four-cylinder Cummins turbo-diesel with a displacement of 3.9 liters. It produces 400 horsepower and 850 Newton meters of maximum torque, compared to 122 horsepower and 142 Newton meters in the existing Prius. The huge turbocharger is visible, as is another small turbocharger hidden behind it; the exhaust fumes that power them come through the Prius’ windshield base. Yes, you read correctly: The drive train’s “tailpipe” is located under the front hood. As a result, the following image was taken during the parking lot test drive: A pitch-black cloud of smoke blasts out immediately in front of the windshield shortly after the rear wheels spin. Meanwhile, the diesel nails like a truck, and a ‘Clean Diesel’ badge on the back window mocks anyone who looks back at the Prius.
Is there a diesel hybrid automobile on the market?
If the BMW doesn’t appeal to you, the Mercedes-Benz C-Class, its closest competitor, might.
If you want a diesel hybrid, you’ll have to go with the C 300 de model. The C-Class is equipped with a turbocharged 2.0-litre diesel engine and plug-in hybrid technology in this edition. On a combined cycle, the C 300 de can return up to 235.4mpg and can travel up to 35 miles on battery power alone when completely charged.
The C 300 de has a strong 302bhp and can accelerate from 0 to 62mph in 5.6 seconds. The sophisticated cabin, which is well-insulated and boasts a variety of high-quality materials throughout, allows you to enjoy this level of performance and efficiency in near silence.
Is it possible to buy a diesel hybrid car?
- Most petrol-electric hybrid cars can drive on electric-only power for short distances, and the engine is shut off when at a stop, decreasing fuel consumption, CO2 emissions, and emissions that have an impact on local air quality. Stop-start systems are, of course, now standard in more traditional vehicles.
- Diesel-electric hybrids are designed to combine diesel-engine efficiency with the capacity to run on electricity alone in urban areas, lowering diesel-engine pollution.
- Hybrids combine the power of a larger engine with the fuel efficiency of a smaller one.
Are diesel engines superior to gasoline engines?
Diesel engines are more fuel efficient, robust, and produce more torque than gasoline engines. They are, however, more difficult to maintain and less convenient to drive than gasoline-powered vehicles. Spark plugs ignite fuel in gas engines, resulting in hundreds of tiny explosions every minute. This is harmful to the engine. Because diesel engines run solely on compression, they have a longer lifespan, with some manufacturers reporting original diesel engines lasting up to 900,000 miles. In cold climates, however, diesel engines must be plugged in because compression changes with temperature.
What will happen to gasoline-powered vehicles after 2035?
- California’s clean-air regulators unveiled a plan this week to increase the sale of electric and zero-emission vehicles while gradually phase out the sale of new gasoline-fueled vehicles by 2035.
- If approved by the California Air Resources Board, the proposal would mandate that by 2026, 35 percent of new passenger vehicle sales be powered by batteries or hydrogen, with 100 percent of sales being net-zero emissions less than a decade later.
- Because cars, trucks, and other vehicles account for nearly 40% of the state’s pollution, converting the transportation sector to cleaner energy is an important part of the state’s climate change strategy.
