Yesterday, Aston Martin gave us our first glimpse at a near-production-spec Valkyrie, and nearly rendered us speechless. Top Gear just got an audience with the Valkyrie's designer, Red Bull F1 mastermind Adrian Newey, who revealed that the Valkyrie's engine is actually derived from an old F1 design. Advertisement - Continue Reading Below The Valkyrie's internal-combustion engine is a 6.5-liter naturally aspirated V12 designed by Cosworth, but interestingly, it's "based loosely" on the 2.4-liter V8 the company used in F1 from 2010 until 2013 with teams like Williams. We've heard this motor will make around 1000 hp, but it's still in testing, so power figures likely aren't finalized. What is certain is that it will sound unbelievably good—Newey insisted on using a 12-into-one exhaust system, because as he says, "that makes it sound like it’s revving twice as high as it actually is." As a reminder, this engine has an 11,000-rpm redline. It's probably going to sound like a V12 … [Read more...] about The Aston Martin Valkyrie’s V12 Is Based On Cosworth’s Last F1 Engine
UM Motorcycles has introduced two new motorcycles, the UM Renegade Duty S, and the UM Renegade Duty Ace, at the Auto Expo 2018. The UM Duty range of motorcycles features a new, smaller 223cc oil-cooled engine mated to a five-speed gearbox. UM Motorcycles aims to launch the UM Renegade Duty S and the Duty Ace in India by July 2018. At launch, these motorcycles will be priced at Rs 1.10 lakh, making them the least priced offerings from the motorcycle brand here.

Mazda is a big fan of bold claims, few of which it has yet to deliver. The Hiroshima-based automaker’s groundbreaking SkyActiv-X engine hasn’t even made it to production, but already there are plans to develop a gasoline engine that the company believes will be as clean as an electric vehicle – at least in the sense of an EV’s supply chain of energy creation. According to Automotive News, Mazda’s powertrain chief revealed the plan during an automotive technical conference in Tokyo, and is planning on calling it SkyActiv-3. The nomenclature is an indication that Mazda is working on its third-generation of SkyActiv high-compression engines. The first-generation SkyActiv-G engines debuted in 2011, and the second-generation SkyActiv-X will only reach the market in the fiscal year ending March 31, 2019. After that, Mazda will prioritise boosting the thermal efficiency of its engines, said Mitsuo Hitomi, Mazda’s managing executive officer in charge of … [Read more...] about Mazda’s SkyActiv-3 engine to be as clean as an EV?
General Motors has confirmed that its Flint engine operations in Michigan will serve as the manufacturing site for the all-new Duramax 3.0L turbo-diesel for the 2019 Silverado. In 2015 GM announced a (U.S.) $263 million investment in its Flint engine operations plant for a new engine line. The 2019 Silverado will be available with six engine/transmission combinations, enabling customers to find the combination of performance, efficiency and value that best fits their needs. One of these choices will be the all-new Flint-built 3.0L inline-six turbo-diesel. The new turbo-diesel will be paired with a Hydra-Matic 10-speed automatic transmission and will feature industry-exclusive technologies that optimize performance and efficiency. It is expected to be an efficiency leader in the Silverado lineup. “The next-generation Silverado builds on the success of our current models, many of which are produced here in Flint. We are proud to expand the industry-leading diesel … [Read more...] about U.S built diesel engine for 2019 Chevrolet Silverado
As fuel prices and economy standards continue their ever-upward trend, large-displacement, big-cylinder-count engines will likely become scarcer. In their stead will come smaller engines with fewer cylinders but not necessarily less power, thanks to tricks like forced induction and direct injection. Small-displacement four-cylinders are likely to see the most growth, with three-cylinders possibly increasing as well. There are a good number of such engines on the market already. A majority of automakers offer at least one engine that has the same displacement as the bottle of soda you order with your pizza — or less — and a handful already employ them as the backbone of their lineup. After all, small-displacement powerplants are already the mainstay of every automaker’s European lineup. We’ve compiled a list of all offerings with an engine displacing two liters or less either currently on the market or just around the corner. Some are good; some are not. A few … [Read more...] about Small Fries: America’s Low-Displacement Engines
As promised, Lotus has released the full monte surrounding its newest sports car, and the British automaker has finally revealed its name — Evora. While we like Eagle better (the vehicle was previously known as Project Eagle), we bet it probably would have been hard to secure it. The first new Lotus since the introduction of the Elise in 1995, the Evora is being billed by Lotus as the world’s only mid-engine 2+2, although don’t expect to be putting two adults in the back seats. Evora is powered by a Toyota-sourced 3.5-liter V-6 massaged by Lotus to produce around 276 horsepower and 252 lb-ft of torque which will more than likely move the Evora’s 2976 pounds with authority. The engine is mated to a six-speed manual transmission. Lotus estimates the Evora will hit a max speed of about 160 mph, with the 0-60 mph sprint coming in under five seconds. Lotus cautions that all the numbers are estimates at this point and the car still has several months of development … [Read more...] about Lotus calls new car Evora, billed as world’s only mid-engine 2+2
Every year we get reader mes-sages asking about the fate of a potential breakthrough engine technology developed by late legendary racing engine builder and high-perf tuner Henry “Smokey” Yunick with his longtime collaborator Ralph Johnson. HOT ROD first reported on this adiabatic, “hot vapor” (or “hot air”) engine in the June ’84 issue. “The Next Step” by C.J. Baker fully explained how Smokey developed a 2.5L (151ci) Iron Duke four-cylinder Fiero engine that met all ’80s emissions standards (with a carburetor and no computer), made 250 hp and 250 lb-ft of torque (compared with about 90 hp and 125 lb-ft stock), went 0 to 60 mph in 6.5 seconds (stock was 12 to 13 seconds), and managed to get as high as 51 mpg on the highway running 93-octane pump unleaded premium gas (the stocker got about 35 mpg on 87-octane). The hot-vapor engine did all this running unheard of high temperatures at an extremely lean air/fuel ratio, in seeming … [Read more...] about What Ever Happened To Smokey’s Hot-Vapor Engine?
The first Great American Racing Series race ran successfully while this engine was still in the process of being built. This story is about that build. In this three-part series we will detail the preparation of the various parts, fitting the parts together, and making the final assembly and dyno’ing the motor. And at the end we will list all of the parts and manufacturers we used and a spec sheet showing all of the sizes and clearances for the build. This is a street stock motor that fits the rules of Circle Track’s new Great American Racing Series and as such, may, or may not, be legal for your particular track or series. CT purposely left the rules a bit loose for the series in order to cover the wide range of rules packages throughout the region where the series takes place. Competitors in this series can run a stock motor right out of the “junk yard,” a crate motor right out of the crate, or run a build motor constructed by the team or an engine builder. … [Read more...] about Building the World’s Most Versatile Engine Package for Oval Track Racing
Chevrolet declared a no racing policy back in the mid-20th Century right when the competition between American makes was getting hot and heavy at the road courses, ovals, and drag strips. In spite of the ban, Chevrolet amassed an amazing collection of racing engines for Bow Tie fans to drool over. That said, it’s definitely worth a look back as we spotlight 10 great racing engines that helped Chevrolet establish and sustain its winning legacy through the decades. And no, Pontiac, Michigan, will not be renamed Chevrolet, Michigan, as development of Chevrolet’s racing engine programs consolidate under the roof of the all-new Powertrain Performance and Racing Center in Pontiac, Michigan. 1. 409 V-8 – The forerunner of the famous Chevy big-block engine family, the 409, debuted in the mid-1961 Chevrolet lineup and quickly found favor with racers for its strong torque and high horsepower capability. The factory rating reached 425 horsepower, making it a powerhouse in … [Read more...] about Check Out 10 of Chevy’s Greatest Racing Engines
