Innovation in chassis design in auto sector is not a new thing. But Chevrolet has gone one step away with Corvette Stingray innovative chassis design. Chevrolet’s announcement of moving the engine behind the driver was not that much surprising. The exciting thing is the starting price of mid-engine “C8” 2020 Corvette Stingray is just $59,995. The figure is low, considering the competitiveness of the market. Ford has sold similar types of cars for more than half a million dollars. Starting price of other competitors like Ferrari, Lamborghini and McLaren in this segment is a quarter-million-dollar. The starting price of Audi R8 and Acura’s NSX are $171,000 and $159,495 respectively. Just compare the prices of Chevy with its competitors. They are way ahead in price.

Building an aluminium-intensive mid-engine sports car at a nominal price is an incredible thing to believe. However, Chevrolet managed to solve this problem on a different scale of manufacturing, unlike others. Giving fierce competition to Ferrari, which builds 5000 cars every year, Chevy sold 40,000 Corvettes with Corvette stingray’s innovative chassis design.

According to Corvettes structure engineer Ed Moss, making cars continuously with low price and in high volume demands careful selection of materials and processes.

Some More Details:

Creating a layout similar to Lotus Esprit and DeLorean DMC12, the engine has to be fixed behind the driver. But 2020 corvette has a central structural tunnel. Lotus Esprit and DeLorean DMC12 are steel cars. Most of the parts of Corvette are made up of aluminium. It has thin-wall aluminium vacuum die castings and Tinkertoy like aluminium extrusions. It has 20 castings including six large at the corners and two for engine cradle. The thin wall used parts varies between 2.5-3mm whereas C7 Corvette has castings of 5-6mm. Aston Martin’s DB-9 has ‘vertical-horizontal’ chassis. But in Corvette, he used metal screws and structural adhesive epoxy for more safety.

The reason behind the using of screws is it has access to only one side. The benefits of glueing are the strength of a bond, which was not a part of the previous generation’s “C7” Corvette. However, C8 has a glue for more than 100 meters. If you look at the chassis, it is open toped and no roof. Once again, it gives competition with its structure being 25-30 percentage stiffer than its competitors. Torsional stiffness allows you to get the load through the tunnel and back to the shock towers. But a car’s engine is at the back. Car’s tunnel carries the weight from the suspension. That’s why this central spine is that much important. To close the tunnel off C8 Corvette uses a carbon fibre panel. It strengthens the system by ten percentage.

Another reason for applying carbon fibre is to cut down 2020 Vette’s cost. It is mandatorily essential to reduce the weight of other components as engine and transmission are at the rear end. For a value for money, a deal company started more carbon pieces.

Conclusion

In this context, we have discussed Corvette Stingray’s innovative chassis design and how it managed to develop its techniques with such a lower price.
