The 2017 ZL1 Camaro’s 10-Speed Transmission Shifts Lightning Fast
Camaro ZL1’s Transmission is a Perfect 10: New 10-speed auto offers quicker shifts than DCT “There is simply nothing like the new 10-speed automatic in the Camaro ZL1,” said Aaron Link, ZL1 lead development engineer. “It delivers nearly instantaneous, lightning-fast shifts that alter your perception of what an automatic transmission can offer in a high-performance vehicle – whether you’re on the street, drag strip, or road course.” The greater overall performance and efficiency are due primarily to the 10-speed’s wider 7.39 overall gear ratio spread, which enhances off-the-line performance with an aggressive first gear ratio of 4.70. Smaller steps between the gears also help the engine maintain the optimal speed for maximum power at almost all vehicle speeds, especially upon corner exit of a track. “The gear ratios are so tightly spaced that the transmission is in the right gear and the engine is at the best rpm for transitions from corners to straights,” said Link. “And with the power from the ZL1’s supercharged LT4 engine, the force you feel in your seat as you accelerate out of a turn will put a grin on your face every time.” Chevrolet testing has shown the ZL1 with the available 10-speed has faster shift times than the Porsche PDK dual-clutch transmission. In fact, the 1-2 upshift is 36-percent quicker than the PDK, while the 2-3 and 3-4 upshifts are 27-percent and 26-percent quicker, respectively. Hundreds of hours were spent integrating the 10-speed’s shift performance with the unique power band of the ZL1’s supercharged 6.2L LT4 engine, which is estimated at 640 horsepower and 640 lb-ft of torque. The 10-speed also has a numerically lower top gear ratio than Camaro’s eight-speed automatics, which allows the engine to run at a lower speed on the highway, enabling even greater efficiency. Creative packaging solutions, which had to accommodate another clutch in comparison to the eight-speed, allow the 10-speed to be the approximate size of Camaro’s other eight-speed transmission. It uses four simple gearsets and six clutches: two brake clutches and four rotating clutches. That’s only one more clutch than the eight-speed, despite having two more forward gears. It is also the latest transmission with an all-new, proprietary electronic control system and performance calibrations. The calibration is unique for the ZL1’s high-performance-oriented driving experience, while additional applications will feature calibrations matched to their respective performance ranges.

From Hot Rods to Muscle Cars, we have them all! There's no charge to join and take in the sights. For more information on our cruise, route and location visit the following link: http://www.littletoncruise.com/location.html As the desire for more substantial factory performance started to build after awakening from its Malaise Era hibernation, Chevrolet decided to crank out some track-ready Camaro's. Today, 1 of the 30 ever made calls Colorado home.
There's no question it's easy for most goatherds and race fans to remember the first-gen Z/28s and their dominance on the SCCA circuit, and the '69 ZL1s and COPO iron-block 427 cars that were fixtures at the dragstrip. What many don't know about were the factory-built 1LE cars from 1989-92 that originated just a little north of the border before moving onto their final completion at the historic Van Nuys plant in California. As consumers, collectors and race teams desire to shed the previous "no power, just a pretty paint job" mantra the last two decades had seemed to produce, therefore giving the SCCA to make tracks announcing the Showroom Stock Racing series which literally stage for GM and other Big Five Automakers to "start their engines", and burn rubber into a more powerful new era. Within days, the Canadian-basedMotorsports Division Players Challenge and GM Motorsports Race Series took advantage of the opportunity that ended up producing the powerful and rarest of rare code R7U Camaro. This build took the 1LE-prepped Camaro, and added a hand-built LB9 305 (205 hp in 1992), special heavy-duty five-speed manual trans, and a performance chip for the TPI-equipped engine computers. Each engine was dyno tested at the factory after assembly, and then the bolts were paint-marked to note it was a sealed piece. These rare beasts were then assembled in Van Nuys, California, alongside their red-haired step-sister Pontiac TransAm's. Unlike the more common 1LE, the R7U code interiors had certain options declared verboten to make installation of roll cages easier and keep weight down. No question this would definitely catch the eyes of true race driver but to also help promote the series and the new "power trend", Chevy made the vehicle also attainable and affordable to a good portion of the general public as a "street legal" coupe. That's where our features ride comes into play being one of only 30 built for the last year of the Canadian racing series, but it never did make it to the track. Subsequently, the vehicle we are speaking of was sold to a close 22 year old relative of GM's lead engineers north of the border who ended up making his way to Northern. Colorado over the period of two years, getting married, starting a family and then trading his prized possession in for a more "practical" vehicle in January of 1994 at Korf Chevrolet in Windsor, CO. At the time, the passion and overall consumer demand for used third-gen F-bodies had dramatically decreased as the launch of the more sleek, more powerful design was taking over showroom floors. The cabin reaction continued right down to the dealers sales desk and offered it for sale at $11,999 when a 15 year old cattle feeders daughter stumbled upon it and noticed something MUCH different about this Camaro in comparison to other Z/28's they'd test driven. At the time, it's second ever and current owner, had no idea why this particular car had the factory installed options other comparable models didn't. This continued for years as it seemed no GM technician or car guru could either. In 1997, after graduating from high school, it's owner parked the blue beast still in pristine condition and headed off to college. Time and the evolution of the Internet helped this once naive small town kid identify the exact answer to the questions so many had wondered or written off long ago. With only 31,091 miles on the clock, the profile F-body now resides in a 15,000 square foot muscle car hideaway close to the now defunct dealership our owners journey began. When new, these 1LEs could be bought for less than $20k and used for much less. While they don't boast high horsepower numbers, they'll be remembered for relative simplicity, affordability, and connection to the dawn of the new performance era. Chevy Cruise 2016 Photos and Best of Show at Chattanooga | 25 of The Most Incredible GM Classic Cars5/1/2016 Chevys Invade the Coker Tire Compound for the 2015 Chattanooga Cruise-In

Chattanooga, Tennessee, isn’t the biggest of cities, but it’s certainly becoming a popular destination thanks to a number of great attractions, restaurants, and nearby scenery. For car guys, it’s becoming an attraction because of the Chattanooga Cruise-In – an event hosted by long-standing Chattanooga companies Coker Tire and Honest Charley Speed Shop. You may have heard of these companies or have an understanding of what each company represents in the old-car hobby, but it’s tough to get the full scope without actually checking out the facilities firsthand. That notion is what started the Chattanooga Cruise In – a free-to-the-public open house to show off all of the cool stuff in the works at Coker Tire and Honest Charley plus a cruise-in to let locals show off their classic cars. Five years later, it has turned into the biggest single-day cruise-in event in the Southeast, and the April 11, 2015 event was one for the record books. The official event hours were 10 a.m. to 4 p.m., but folks rolled in as early as 7 a.m. to get parked. With parking on the streets and parking lots that surround the Coker Tire compound, space was somewhat limited, even though the staff had reserved more street closures than normal. Hundreds of Camaros, Novas, Chevelles, Corvettes, and more rolled into the event, with everything from restored stockers to full-on Pro Touring builds on hand. Food vendors and neighboring restaurants offered great food for the attendees, while several door prizes kept folks anxiously awaiting the results of the 3 p.m. drawing. By 4 p.m., the crowds had dispersed and the flurry of car-guy activity was over. At the end of the day, the Chattanooga Police Officers who worked the entry gates estimated 2,000 cars and 15,000 spectators had entered the event. Many of those cars proudly wore the Chevy Bow Tie, so we picked out our favorites, and put together a special gallery of the best Chevys at the 2015 Chattanooga Cruise-In. |
