LAS VEGAS — Today the Colorado ZR2 will be competing in its third Best in the Desert’s General Tire Vegas to Reno race. Since the truck made its debut at the 2017 Vegas to Reno, the ZR2 has been piloted by Chad Hall of Hall Racing in 11 Best in the Desert races, logging 3,275 miles in some of the most challenging off-road conditions imaginable.

A total of 434 vehicles have competed in all 11 races in the Best in the Desert series since the ZR2’s race debut. As a testament to the grueling nature of off-road racing, the ZR2 is one of only four vehicles — fewer than 1% of total entrants — that completed each of these 11 competitions.

“Our goal with the Best in the Desert competition is to push the engineering and development of the Colorado platform in the most extreme conditions imaginable,” said Mark Dickens, chief engineer, Government Programs, Performance Variants, Parts and Motorsports. “We’ve already learned things over the past two years that have shaped our off-road portfolio, including the performance parts and motorsports catalog, production vehicles and GM Defense projects.”

Not only has the ZR2 survived the challenges of the Best in the Desert series, but the Chevrolet and Hall Racing teams have found ways to make the truck more robust and efficient since its debut. The truck finished its first 2017 Vegas to Reno in 18 hours and 51 minutes. The following year, the ZR2 improved its finishing time by more than four hours to 14 hours and 34.5 minutes.

The production-based ZR2 is one of the only vehicles that competes in the stock 7300 class. It regularly beats the race times of a wide range of off-road vehicles — everything from dune buggies to modified Ford Raptors, Jeep Wranglers and trophy trucks in the more extreme and well-represented Class 6000 and 6100 classes.

World-renowned off-road racer and engineer Chad Hall received one of the first Colorado ZR2s ever built in May 2017, and he’s been running it ever since. His vehicle began life as a Red Hot Crew Cab ZR2 powered by a 3.6L V-6 engine paired with an eight-speed automatic transmission.

This vehicle was modified with prototype suspension and driveline parts that were developed into 15 factory race components now available to Colorado ZR2 customers. The truck has since been updated with the same production parts available through the Chevy performance catalogue. This portfolio includes race-tuned versions of ZR2’s Multimatic Front and Rear Long Travel DSSV shocks with up to 15 percent more suspension travel in the front and 10 percent in the rear.

Other factory racing parts include a 1.5-inch Body Lift System, Front and Rear Jounce Shock Systems, ZR2 Steel Driveshaft, Plunging Ball Spline Half Shaft System and severe duty Tie Rod Sleeve Systems.

“In off-road racing, your speed comes from your suspension, not your engine. Usually, when you modify the suspension on a stock truck, the rest of the truck can’t keep up with it,” said Chad Hall. “However, the Colorado is such a great platform, everything seems to work at the same level. This is true even during off-road races, which are some of the most punishing miles you’ll ever put on a truck.”

Hall’s race truck was recently upgraded with ZR2 Bison skid plates on its engine, transmission and differential as well as other American Expedition Vehicles Colorado accessories such as Crestone DualSport beadlock wheels and a snorkel for air filtration while racing in dusty climates. For its third year, the ZR2 race truck also receives a new wrap that incorporates the GM Defense logo and additional HID KC HiLiTES to improve nighttime visibility.

This is our next video of primitive survival skills. In this video we show you how to create a primitive pulley. Pulley is a great invention and it is still used today. Pulley modifies the power of the force so that we can lift an object easily. At first we cut the wood to make rollers, took the bark to make zipper, cut a piece of tree to make the shaft. We made this video purely by primitive technology. We took a lot of time to complete it. We will continue to make the next video on primitive survival skills.

Two wheels machine kind

In two wheels of BMWs, it is features that there are a lot of examples of adopting a mechanism different from the other two wheels. Especially, there are a lot of one to adopt two horizontal opposing cylinder engine and either a dry single board clutch and shaft drive or this.

* Length is put and two horizontal opposing cylinder engine.

It was adopted for "R32" first in 1923. The length putting layout to which the cylinder projects right and left is taken, and a basic layout to the drive shaft is alive and well as it is in R series today through the clutch and the transmission.

* Shaft drive

All cars that exclude the F&G series are the shaft drive models in BMWs though being equipped only by partially two wheel car in a Japanese car because the tail lift when starting is disliked. It is an advantage that it is almost maintenance free compared with the chain drive, and there is no power loss by sliding of the chain.

* Dry single board clutch

This method that the engine clutch and the changing the speed machine can be thinned more than a general multiplate wet clutch to queue up in length in the putting the length of the engine layout is adopted. (The multiplate wet clutch is adopted it is necessary to reduce the diameter to thickness in the K series of an engine horizontal putting instead of being able to do room. )

It is ardent to the adoption of the new departure, and adopts the following technologies for a car
on the market one after another in advance of another manufacturer in recent years.


* Pararebarriasaspention

Suspension developed to suppress tail lift when starting becoming problem in shaft drive being adopted first with R100GS in 1987. Naming is done by the synthesis of "Parallel" and "Lever".

* Tererebarfrontosaspention

It the first adopts it with R1100RS put on the market in 1993. Naming is done by the synthesis of "Telescopic" and "Lever".
Handling changes by the two-wheeled vehicle in a general telescopic fork reception desk suspension so that the caster angle may change along with the stroke, too. Moreover, the steer stability becomes small as the caster angle after it sinks greatly at the sudden deceleration and the buffer stroke is insufficient stands. Under such a condition, extremely dangerous phenomena such as the steering wheel's the front wheel's splashing when a strong pushing up is received from the road and swinging are generated. It is a thing developed to avoid this.
There is an evaluation of transferring it from the little movement of the front wheel forward when the suspension shrinks while excelled in the control stability compared with a telescopic expression by one step in a super-high-speed buffer ability, too. Moreover, it is difficult on the structure to enlarge the stroke.
By the way, it is BMWs to have adopted the telescopic expression reception desk suspension for the two-wheeled vehicle of mass-producing on the market first in the world. (R12,1935)

R series(two horizontal opposing cylinder engine)

R is taking of the initial of Rad (wheel and bicycle). The camshaft is on the side of the cylinder, and the valve can be classified there into drive and high cam OHV by a short push rod. The ground amount of the cylinder is higher than that of old R series.
