Mild Hybrid Cars Explained

Welcome, car enthusiasts and eco-conscious readers, to an electrifying journey into the world of mild hybrid cars! In today's fast-evolving automotive landscape, the pursuit of greener and more fuel-efficient transportation options has taken centre stage. Amidst this transformation, one intriguing player has emerged – the mild hybrid car. But what exactly is a mild hybrid, and what advantages do they offer?

In this blog, we're taking you on a thrilling ride where cutting-edge technology and eco-consciousness come together to redefine the way we drive. From regenerative braking to intelligent start-stop systems, we'll unravel the inner workings of mild hybrids and explore some of the best options available.

What is a mild hybrid?

Now, you might be wondering, what exactly is a mild hybrid car? Well, a mild hybrid is a type of hybrid vehicle that combines an internal combustion engine with a small electric motor and a battery pack. Unlike full hybrid or plug-in hybrid vehicles, mild hybrids do not have the capability to run solely on electric power. Instead, the electric motor assists the internal combustion engine, providing additional power during acceleration and supporting various functions to improve fuel efficiency.

The electric motor in a MHEV (Mild Hybrid Electric Vehicle) is generally smaller and less powerful compared to those found in full hybrids or plug-in hybrids. It primarily functions as a supplement to the engine, rather than being the primary source of propulsion. Mild hybrids typically use regenerative braking to capture and store energy during deceleration, which can then be used to power the electric motor and assist the engine during acceleration.

One of the key features of mild hybrid cars is their start-stop functionality. When the car is at a stop, like at a traffic light or during congested traffic situations, the engine will automatically shut off to save fuel. Once the driver releases the brake pedal or accelerates, the engine quickly restarts with the assistance of the electric motor.

Advantages of Mild Hybrids

Mild hybrid cars offer a range of advantages that make them an attractive choice for many drivers. While they may not provide all-electric driving like plug-in hybrids or full electric vehicles, they excel in several key areas.

• Improved Fuel Efficiency: One of the main advantages of mild hybrid cars is their improved fuel efficiency. This is especially noticeable in stop-and-go city traffic.

• Reduced Emissions: Mild hybrid cars help reduce greenhouse gas emissions and air pollutants compared to traditional petrol or diesel-powered vehicles.

• Seamless Integration: Mild hybrid technology is designed to seamlessly integrate into existing vehicle platforms, making it a relatively cost-effective way for automakers to improve the efficiency of their fleets.

• Regenerative Braking: Mild hybrids make use of regenerative braking systems, which capture and store energy typically lost as heat during braking. This energy is then used to recharge the battery, further improving fuel efficiency.

• Enhanced Torque: The electric motor in a mild hybrid provides instant torque, improving acceleration and responsiveness. This can enhance the overall driving experience. 

• Cost-Effective: Mild hybrids are generally more affordable than plug-in hybrids or all-electric vehicles. 

• Durability: Mild hybrid systems are designed for long-term durability, as they often involve less complex technology than full hybrids or plug-in hybrids.

Do mild hybrid cars need charging?

No, mild hybrid cars do not require external charging. Unlike plug-in hybrids or fully electric vehicles, mild hybrid cars do not have a plug-in capability to charge their batteries from an external power source. The small battery pack in a mild hybrid car is primarily charged through the process called regenerative braking.

The advantage of not requiring external charging is that mild hybrid cars offer the convenience of refuelling at traditional fuel stations like conventional vehicles. Drivers of mild hybrid cars can simply fill up the fuel tank as they would with a regular petrol or diesel vehicle, without the need to worry about finding charging infrastructure or waiting for the battery to charge.

How fuel efficient are mild hybrid cars?

On average, mild hybrid cars can achieve fuel efficiency improvements of around 5% to 15% compared to their conventional counterparts, depending on the driving conditions and the extent to which the mild hybrid system is utilised. However, it's worth noting that these figures can vary, and the actual fuel efficiency gains may be influenced by factors such as driving style and road conditions.

While mild hybrids may not achieve the same level of fuel efficiency as plug-in hybrids or fully electric vehicles, they offer a more accessible and affordable option for those looking to improve their fuel economy and reduce emissions. Mild hybrid technology serves as a stepping stone toward greener transportation options, bridging the gap between conventional combustion engines and more advanced electrified vehicles.

Mild Hybrid vs Plug-In Hybrid

As many continue to embrace electrification, two desirable options that have claimed traction are mild hybrid and plug-in hybrid (PHEV) cars. These two hybrid technologies share some similarities but also have key differences, catering to various driving needs. The choice between a mild hybrid and a plug-in hybrid depends on your driving patterns, environmental concerns, and budget. If you primarily drive short distances or want to reduce emissions without relying on public charging infrastructure, a PHEV might be the better choice. However, if you want a simpler and more affordable way to improve fuel efficiency without compromising on long-distance capabilities, a mild hybrid could be the right fit.
