Unveiling Audi’s MHEV Plus: The New Standard for Performance and Efficiency in Combustion Vehicles

• To boost the performance, efficiency, and emissions of the combustion engine, Audi introduced the MHEV Plus with a generator, belt alternator starter, and lithium-ion battery.
• The system is said to offer several advantages, including partial electric vehicle driving, energy recuperation, and immediate driving dynamics for improved comfort, performance, and long-distance efficiency.

In its new series of A5s and Q5s, Audi unveils a pioneering MHEV plus technology that heralds a new era in fuel economy and driving comfort. Given their origins within the Premium Platform Combustion (PPC) family, these models come with an advanced eco-friendly 48-V mild hybrid system that not only favours carbon emissions but also helps with performance and the agility of the vehicle.

Powertrain generator-PTGs work with a belt-alternator-starter (BAS) and a lithium-iron-phosphate battery for harmonising electric and combustion power. This entire mini-system helps firstly to support the combustion engine and then optimise driving dynamics through partial electric driving, improving overall fuel consumption.

Improved Comfort and Efficiency in Driving

Downsized but powerful, the electric drive module represented in the MHEV plus system enhances performance. Can perform up to 18 kW of electrical power; the drivetrain delivers torque peaking from 0 rpm at 230 Nm. Thus, enhancing low-speed acceleration, as is the case with city driving.

The PTG is an efficient operator up to a disengagement point of about 140 km/h to conserve energy. The same can also facilitate regenerative braking; depending on the speed, regeneration would get activated by the system synchronously with the vehicle braking system. Mainly intended for optimisation in the storage and reuse of power to ensure maximum fuel savings.

Fuel Savings and CO2 Reduction

A system such as the MHEV-plus grants a substantial amount of fuel savings and CO₂ emissions reduction. As an example, the A5 2.0 TDI can save 10 g/km of CO2 emissions and reduce fuel consumption by 0.38 l/100 km; on the other hand, through the use of the 3.0 TFSI V6 engine, carbon dioxide emissions reduction could be as much as 17 g/km and fuel consumption by 0.74 l/100 km. This technology represents a perfect compromise between performance and environmental consideration, great for those seeking greener driving without sacrificing power.

Customarily Speaking

Audi tends to focus on delivering MHEV plus technology, which will ensure customers’ overall satisfaction. Several good things come with this system: electric coasting, energy recovery, and driving on electricity—no parking and manoeuvring. These are considered nothing more than spicing up the entire experience of driving with enhanced dynamics of the car with agility and rapid responsiveness to start.

Torque delivery from the PTG makes the vehicle jumpy at slow speed levels by providing low initial torque; thus, it responds better to stop-and-go conditions in heavy traffic. Besides this, the MHEV plus technology grants low-speed electric operation, yet combustors do not start until additional energy is required.

All About Advanced Battery and Regenerative Braking

At the heart of the MHEV plus system sits the lithium-ion battery made with lithium iron phosphate (LFP). With 37 ampere hours of storage capacity, the battery facilitates efficient power management as well as ensuring optimal working conditions through a low-temperature water-cooling circuit. This technology allows the lithium-ion battery to attain high energy recovery rates and rapid recharging, facilitating the operation of the vehicle even under the extreme conditions of severe driving.

The integrated brake control system (iBRS) further enhances energy recovery by enabling pressure-retaining braking and regenerating braking control from the iBRS without utilising any mechanical wheel brakes; this enhances fuel economy further and adds to the driver experience with its seamless, nuanced braking feel.

Optimised Driving Strategy for Maximum Efficiency

The MHEV Plus system skilfully controls the coordination of the combustion engine, PTG, and BAS. The control maximises energy efficiency and quickly responds to driver input against the ever-changing situations of battery charge state and selected driving mode.

Under modes such as D (for economy) and S (for sport), the system changes the driver’s electric power delivery choices. Economy mode focuses on energy recovery and electric power-boosting for the combustion engine, whilst sport mode focuses on quick responsiveness and maximum power output for dynamic driving.

Long-Distance Travel and Increased Range

MHEV plus systems improve the overall range of cars, which makes them more amenable to long-distance travel. The system works efficiently, thereby allowing the driver to go farther on a tank of gas and increasing comfort and convenience for long journeys.

Audi’s MHEV + technology achieves an amazing blend of performance, efficiency, and environmental responsibility, making it a welcome addition to the A5 and Q5 lineup. By combining modern hybrid technology with Audi’s commitment to customer satisfaction, this system ensures smooth, efficient driving without sacrificing power or enjoyment.

This technology will not be available in the United States due to differing client needs.
