Mahindra has been betting large connected its electrical SUVs and rightly so. We drove these cars precocious and were mighty impressed with the wide product. The cars volition soon beryllium connected Indian roads, but meanwhile, Mahindra had arranged for a Tech Day wherever they showcased each the exertion that has gone into the improvement of these cars. It was a 2-day lawsuit that took spot successful Mahindra?s mill successful Chakan, Pune. This is wherever arsenic of now, the batteries are being assembled and the cars are besides being manufactured. Let?s instrumentality a look astatine the highlights of the event. Do stock immoderate further method highlights that you tin from the pictures.
Day 1
Of course, the 2 cars successful question were parked astatine the venue. Both cars stock the aforesaid INGLO architecture and contempt the antithetic sizes, they some person the aforesaid wheelbase:
There were a full of 8 stalls displaying details of antithetic areas of the car:
We?ll commencement disconnected with the show of the inclined chassis of the INGLO architecture:
A person look astatine the inside. You tin spot the steering mechanics and the HVAC mechanics arsenic well:
On the different side, you tin spot the remaining portion of the HVAC portion and besides the brake booster portion connected the left:
A look astatine the beforehand suspension strategy and the frame:
This was conscionable a miniature mode assembly of the car displaying the suspension and braking systems:
A chopped conception of the beforehand and rear suspension. These are continuously adaptable semi-active dampers. There?s a solenoid valve astatine the bottommost (green-coloured switch) that is liable for performing continuous adaptable damping:
This is the beforehand suspension system. Mahindra claims that the strategy has the highest suspension question of 185 mm:
If you look closely, you tin spot that the little power limb is divided into 2 links. This allows the engineers to tune the comfortableness and handling characteristics separately:
As you tin see, the steering rack is mounted successful the beforehand of the beforehand axle which is thing that?s imaginable connected EVs and not IC motor cars. Without getting into overmuch detail, the front-mounted steering rack improves high-speed understeer. With a rear-wheel thrust car, you don?t privation oversteer wherever the rear extremity steps out:
This is the autarkic multi-link (5 links) rear suspension assembly. The rear suspension has a question of 205 mm:
The horizontal nexus that you spot successful beforehand of the strut is the toed nexus that is claimed to amended camber linearity. Even the sub-frame plan is claimed to person been optimized for artillery extortion successful lawsuit of a rear crash:
A look astatine the framework successful detail. The reddish arrows that you spot present amusement the load way successful lawsuit of a frontal crash. The greenish arrows amusement the load way successful lawsuit of a broadside rod impact:
In lawsuit of a frontal impact, determination are 3 large zones successful the beforehand of the car ? crumple zone, absorption portion and absorption zone. In the absorption zone, Mahindra has added a cradle load way which is the portion that you spot successful the middle. This cradle fundamentally crumbles beneath and is claimed to supply 3x vigor absorption successful examination with ICE cars:
As mentioned earlier, the greenish lines show the load way for broadside impact. Note that the artillery battalion besides acts arsenic a portion of the framework and hence adds to the rigidity of the structure. The load organisation is 52% by the operation and 48% by the artillery battalion frame:
This is the BIW worldly organisation exemplary of the BE 6. Unfortunately, I couldn?t find the nonstop organisation of antithetic types of steels:
There was besides a objection of the airbag deployment sequence. The basal thought is that successful antithetic types of crashes, the sensors relay the connection to the airbag ECU which successful crook sends signals to the respective airbags and besides cuts disconnected the high-voltage system:
This multilayer expanse that is placed supra the inverter is claimed to trim the sound and amended NVH:
Here?s a look astatine the steering system. It has a turning ellipse of little than 10 meters and has 2.65 turns from fastener to lock. You besides get a rack assistance centrifugal for amended response. Note that the cars travel with ADAS features and besides car parkland assist:
The steering rack has a adaptable cogwheel ratio. This means that the transportation is constrictive successful the mediate and wider towards the ends:
Here?s a amended mentation of the adaptable cogwheel ratio:
This is the steering file assembly:
The INGLO level cars get brake by wire. This includes an integrated physics brake booster. This assembly that you spot present has a brake booster, vacuum pump and ESC controls integrated. Also, adjacent to it, you tin spot the beforehand brake caliper:
Here?s the rear brake caliper and the brake discs. The discs person a tiger claw plan for amended thermal stability:
These are the instrumentality hub assemblies for driven and non-driven wheels. Externally, there?s not overmuch difference, but they are antithetic connected the inside:
The tyres person foam successful them to trim sound levels. The claimed simplification is 3-4 decibels:
Here?s a look astatine the Gen 2 compressor on with different parts of the HVAC system. You person the h2o pump astatine the backmost close and the chiller astatine the right:
Here?s a look astatine the HVAC assembly:
You person an progressive grill shutter assembly. This reduces aerodynamic resistance by closing the grille opening country to the required level astatine higher speeds. This helps successful improving the range:
A look astatine the compressor and the chiller with physics enlargement valve:
