Chevrolet is making huge news today, revealing most all of the details about its new, fifth generation Small Block V8 engine dubbed LT1 the very mill that will power the upcoming 2014 Corvette. Note that we'll be updating this post all morning as the information keeps streaming in, so check back often.
Preliminary numbers suggest no less than 450 horsepower and 450 pound feet of torque.
The Corvette's new LT1 V8 engine is, no surprise here, set to make the car very competitive within its class. Preliminary numbers suggest no less than 450 horsepower and 450 pound feet of torque for the 6.2 liter engine, as well as an estimated 0 60 mile per hour time of less than 4.0 seconds when installed in the base C7. To put those numbers in perspective a bit: The LT1 not only has a far higher specific output than the 6.2 liter LS3 that it replaces up at least 20 hp and 26 lb ft but its torque is seemingly competitive with that of the 7.0 liter LS7 that lives in the heart of the current Corvette Z06.
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 11.5:1 compression ratio, all while coming in a claimed 40 pounds lighter and four inches shorter than the 4.4 liter twin turbo V8 by BMW. Chevy also notes that while premium fuel is recommended replica breitling Bentley 6.75, 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 75 year old Tonawanda plant, which happens to be where Chevy's original small block V8 was produced way back in 1955.
There is a load of detailed information from GM, in 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.
UPDATE: Press release added below with more details.

All New 2014 Corvette LT1 V 8 a Technological Powerhouse
Advanced technologies including direct injection, active fuel management, continuously variable valve timing support advanced combustion system
Preliminary output of 450 horsepower (335 kW) and 450 lb. ft.
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.
"Our objective for the development of the all new LT1 was to raise the bar for performance car engines," said Mary Barra, senior vice president http://www.asmallheaven.net/replica-breilting-certifie-disocunt-uk.html, global product development. "We feel that we have achieved that by delivering a true technological masterpiece that seamlessly integrates a suite of advanced technologies that can only be found on a handful of engines in the world.
"What makes this engine truly special is the advanced combustion system that extracts the full potential of these technologies. 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:
The most powerful standard Corvette ever, with preliminary output of 450 horsepower (335 kW) and 450 lb. ft. of torque (610 Nm)
The quickest standard Corvette ever, with estimated 0 60 performance of less than four seconds
The most fuel efficient Corvette ever replica breitling Avenger, exceeding the 2013 EPA estimated 26 miles per gallon on the highway.
"The Holy Grail for developing a performance car is delivering greater performance and more power with greater fuel economy and that's what we've achieved," said Tadge Juechter, Corvette chief engineer. "By leveraging technology, we are able to get more out of every drop of gasoline and because of that we expect the new Corvette will be the most fuel efficient 450 horsepower car on the market."
Advanced combustion system optimized with 6 million hours of analysis
"The Corvette LT1 represents the most significant redesign in the Small Block's nearly 60 year history building on its legacy to make one of the world's best engines even better," said Sam Winegarden, vice president, Global Powertrain Engineering. "More than just great horsepower, the LT1 has been optimized to produce a broader power band. Below 4,000 rpm, the torque of the Corvette LT1 is comparable to that of the legendary, 7.0L LS7 out of the current Corvette Z06. The LT1 is a sweetheart of a power plant and drivers will feel its tremendous torque and power at every notch on the tachometer."
Increased power and efficiency were made possible by an unprecedented level of analysis, including computational fluid dynamics, to optimize the combustion system, the direct injection fuel system, active fuel management and variable valve timing systems that support it. 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 http://www.asmallheaven.net/replica-a-lange-sohne-disocunt-uk.html, 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 fake Cartier Pasha, is refined to support the LT1 AFM and direct injection systems to further optimize performance, efficiency and emissions.
These technologies support the all new http://www.asmallheaven.net/replica-breilting-bentley-mulliner-disocunt-uk.html, 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.
