SUVs are known to offer a more practical answer to mobility across tough conditions, while vehicles in the MPV segment are essentially large people-carriers offering comfort and convenience. This required Mahindra & Mahindra Ltd (M&M) to develop a vehicle much different from its usual offerings, for which the Mahindra Research Valley (MRV), along with the Mahindra Automotive North America (MANA), Detroit, and Pininfarina carried out collaborative engineering. The Marazzo was thus born as the company’s first multi-purpose vehicle (MPV) in September 2018.
The Mahindra Marazzo is an MPV that offers a host of first-in-segment engineering and technology features in the Indian automotive space. These features range from patented ‘Body-on-Frame-FrontWheel-Drive’ architecture, electric power steering and all-wheel disc brakes, to the quietest cabin and Surround Cool Technology with fully-automatic temperature control. However, this article focusses on the powertrain of the new Marazzo, which in itself features a range of technologies that are aimed at making the engine and transmission combination as refined as possible.
Velusamy R, Senior Vice President, Product Development – Automotive Division, M&M, who works out of the MRV in Chennai, took us through a detailed journey of the development of the Marazzo’s powertrain. Velusamy focussed on the technologies utilised to achieve the three main goals of the new engine – increased fuel efficiency, high levels of refinement and weight reduction. He also brought out the work that the company has carried out with regards to the transmission, which also leads to improved vehicle efficiency and reduced noise vibration and harshness (NVH) levels.
MAIN REQUISITES
Following the success that M&M has seen with its 2.2 l, mHawk diesel engine that is featured in multiple models of the brand, the company has been toying with the idea of making a refined engine, noted Velusamy. The MPV segment is a comfort segment, where overall refinement is a key criterion. This required the company to make fundamental, architectural changes that would lead to increased levels of refinement, but without raising costs, he added.

Sound Generation For Enhanced Road Safety
With an ever-increasing number of fully electric and hybrid vehicles entering the market, we are witnessing a change in the acoustic experience in and around the car. The silent nature of the electric powertrain means that other road users miss the familiar acoustic cues that warn them of an approaching vehicle. To remedy this situation, Harman is working on various noise management solutions.
OBJECTIVE ASSESSMENT OF THE SAFETY CONTRIBUTION OF TODAY'S AUTOMOTIVE HEADLAMPS
Good lighting makes a major contribution to road safety. In 2011, the International Commission on Illumination (CIE) presented an evaluation system for headlamps that can objectively assess the quality of illumination and glare limitation. New light sources like LEDs and lighting functions (glare-free high beam, partial high beam) have been available for several years, so that an extension of the proven CIE method is necessary, which takes into account, among other things, changed switch-on and service lives of new lighting functions and represents a generally understandable evaluation system. An evaluation system presented in the following by the Technische Uni versität Darmstadt, which was developed by an encompassing expert commission, is intended to provide representative data and enable an objective evaluation of headlamp performance.
RAPIDO RE-INNOVATES TO CATER TO POST COVID-19 LAST MILE CONNECTIVITY
The rapid pace of urbanisation in the country has witnessed cities expanding and subsuming surrounding villages and smaller towns, evolving into Tier II and III cities.
FUNCTIONAL SAFETY STANDARDS TOP PRIORITY FOR FUTURE AUTOMOTIVE DEPLOYMENT
Increasing levels of electronic content in vehicles result in a large amount of software that is required to run the scenes behind the mechanical aspects of a vehicle. Electronic systems in automobiles are part of every section, from the powertrain to comfort and convenience systems as well as all types of safety equipment. This makes electronics and the software running these systems a critical part of the equation for future mobility solutions. In addition, putting standards in place to measure methods of developing, testing and functioning of such electronic systems also becomes highly relevant.
“BYD'S EV STRATEGY TO ENCOMPASS MOST FORMS OF TRANSPORTATION NEEDS IN INDIA”
The country’s electric vehicle (EV) ecosystem is grappling with a plethora of challenges even as it is striving to wriggle itself out of the ‘nascent stage’ tag. In an exclusive chat with Auto Tech Review, Zhang Jie Ketsu, Executive Director, BYD India shares his perspective on the current EV scenario and how the company intends to progress faster in the Indian automotive industry
SAFETY IN ELECTRIC AND AUTONOMOUS CARS – SIMULATION OF COMPLEX CRASH SCENARIOS
Electric and autonomous vehicles allow for novel seating arrangements and packaging strategies, presenting new safety challenges. Physical crash testing must be supplemented with virtual simulation to ensure vehicle safety on shorter development cycles. With its Simcenter Madymo MBS software, Siemens provides improved runtimes and the Active Human model, enabling accurate and rapid occupant safety analysis in complex crash scenarios.
KIA SONET – A MIGHTY OFFERING IN THE COMPACT SUV SEGMENT
It wouldn't be wrong to say that Kia Motors India has taken the Indian market by storm in less than 12 months of its presence in the market.

Marking a key milestone in Nissan’s transformation strategy, Ariya ticks a lot of boxes highlighting the strengths of the global automotive giant.
BETTER SAFETY WITH EMERGENCY BRAKE ASSIST FOR MOTORCYCLES
Rear-end collisions with a slower vehicle suddenly cutting into the lane and intersection accidents with cross-traffic are among the most frequent motorcycle accident types. Continental is now developing an emergency brake assist, which detects an imminent collision with a vehicle ahead or with an obstacle, warns the rider and supports him during braking
