according to Corvette chief engineer Tadge Juechter: “Simply put, until recently it was not possible to create an open-roof structure strong enough to meet. Mat Juechter is not only a huge fan of the Corvette, but he is also the father of Tadge Juechter who was the Chief Engineer on the C7. Tadge Juechter didn't blink as the Chevrolet Corvette Stingray Juechter is the most eloquent engineer we've ever met (and as an active.

There are no plans for right-hand drive. The MR suspension calibrations are different. We will make spring rate changes if needed, but we are not planning to do that.

Every car that goes to Europe and the Middle East has Z51 cooling as standard equipment. What key competitors did you benchmark? We spent time in cars like the Porsche and the Ferrari We evaluate competitive cars, as everyone does.

Any time we do a new Corvette, we are only somewhat influenced by competitors. We are largely influenced by what we think the car should be. The e-LSD can go from nearly open to fully locked. This allows tailoring in corners and improved handling dynamics. In a conventional differential, you get some body roll upon transitions—what we call head toss. With the e-LSD, the car feels planted in those conditions.

With the traction control features active, you can matt the throttle with the wheel at full lock and power out of a corner.

The Performance Traction Management option offers five levels of active handling on the Z Did you consider moving away from run-flats? We have a bona fide competition between tire manufacturers. We give them a rough set of requirements, one of which is run-flat technology [zero-pressure, at-speed, to a certain distance].

The structure of the sidewall for run-flat technology has evolved so you can now get a quiet, compliant tire. They telegraph very well at the limit, with excellent feedback, and good wear resistance for performance tires. We have systems, and we have to validate everything. How much do older, core Corvette buyers influence the new car?

Does it always have to be front-engined? They certainly have influence. But we always look to the future. The car needs to continue to look toward the future. And yet it's come to mean so much more. Perhaps the real reason roads are special is that every road leads us to someplace we're not - but could be. At Chevrolet, roads are our springboards. They challenge us, taunt us and guide us to create better, more exciting, more ingenious ways to move through life.

Roads drive us to places we've never been before. And we'll never stop seeking out new ones. It isn't just a word. For the designers of the all-new Corvette Stingray, it was a mantra. Throwing off the constraints of tradition, our engineers started from scratch to build a revolutionary sports car with the performance prowess, aesthetic impact and fine craftsmanship worthy of the Stingray emblem.

Born through a synthesis of precision engineering and racing technology, the Corvette Stingray is a stunning argument against the ordinary.

The use of carbon-fiber and carbonnano- composite structures further reduces weight to achieve optimal handling, balance and acceleration. Geometric shapes transition smoothly from soft curve to crisp edge.

Air flows effortlessly to reduce drag and optimize performance. Increased downforce keeps the vehicle planted, while functional exterior vents create a totally new breathing experience to reduce lift and minimize drag.

The advanced ventilation systems help air flow from front to back, cooling critical components to improve vehicle handling. Stunning design, meet racing strategy. And the Stingray is designed to challenge every expectation. How do you top a stingray? Designed as an open-top vehicle from the outset, no additional reinforcements are required. The vehicle remains a pure, precision-born machine. This year, the convertible features a fully electronic top that can be lowered remotely using the key fob or while driving at speeds up to 30 mph — without the need for mechanical latches.

With the top up, a thick design ensures maximum sound absorption for a quiet cabin. And when you decide to put the top down, it hides beneath a body-color tonneau cover that flows down in a waterfall design between the seats. Available removable roof panel options include: Preliminary numbers suggest no less than horsepower and pound-feet of torque for the 6. To put those numbers in perspective a bit: The LT1 not only has a far higher specific output than the 6.

With all that power and accelerative performance, Chevy engineers are still keeping fuel economy in mind — with the help of cylinder deactivation, the new Corvette powerplant is expected to deliver more than 26 miles per gallon on the highway, though figures for city driving are still unknown.

The new small block also benefits from the latest advanced engine tech like direct injection, continuously variable valve technology and a relatively high Chevy also notes that while premium fuel is recommended, it is not required with the LT1. We're also told that a dry sump oil system is optional a traditional wet sump unit is standard.

GM is calling the LT1 its most advanced combustion system ever. The company analyzed literally hundreds of systems to get to this final product, including crunching over 6 million hours of CPU time dedicated to combustion system optimization, and nearly 10 million hours when combustion, structure, cooling systems, lubrication and vent systems are factored in.

In fact, the motor and its systems are so advanced that an academic SAE paper is being written to explain the whole shebang.

The engine will also be built at the company's year-old Tonawanda plant, which happens to be where Chevy's original small block V8 was produced way back in There is a load of detailed information from GMin our gallery of slides from the presentation this morning. Please excuse the lowish quality of the images here — we decided to err on quality in favor of bringing you all of the LT1 info we could, as fast as was possible. Press release added below with more details.

For much more information on the new small block, including videos of it on the dyno and additional tech details, click here for our more detailed feature. The new Corvette LT1 engine, the first of the Gen 5 family of Small Block engines, combines several advanced technologies, including direct injection, Active Fuel Management and continuously variable valve timing to support an advanced combustion system.

The art and science behind that combustion system make the Corvette LT1 one of the most advanced V-8 engines in the world," said Barra. Output, performance, and fuel economy numbers will not be finalized until early next year, but the new LT1 engine is expected to deliver: Below 4, rpm, the torque of the Corvette LT1 is comparable to that of the legendary, 7.

The LT1 is a sweetheart of a power plant and drivers will feel its tremendous torque and power at every notch on the tachometer. More than 10 million hours of computational analysis were conducted on the engine program, including 6 million hours CPU time dedicated to the advanced combustion system. Direct injection is all-new to the engine architecture and is a primary contributor to its greater combustion efficiency by ensuring a more complete burn of the fuel in the air-fuel mixture.

This is achieved by precisely controlling the mixture motion and fuel injection spray pattern. Direct injection also keeps the combustion chamber cooler, which allows for a higher compression ratio. Emissions are also reduced, particularly cold-start hydrocarbon emissions, which are cut by about 25 percent. Active Fuel Management AFM — a first-ever application on Corvette — helps save fuel by imperceptibly shutting down half of the engine's cylinders in light-load driving.

Continuously variable valve timing, which GM pioneered for overhead-valve engines, is refined to support the LT1 AFM and direct injection systems to further optimize performance, efficiency and emissions. These technologies support the all-new, advanced combustion system, which incorporates a new cylinder-head design and a new, sculpted piston design that is an integral contributor to the high-compression, mixture motion parameters enabled by direct injection.
