介绍丰田HILUX和TACOMA
转载自BRIAN894X4.COM, 介绍的比较详细,对准备买TACOMA的有点用。 This page high lights the differences between the North American spec. Toyota pick-up and later Tacoma verses the overseas Hilux. Make no mistake. Especially in recent years, these two trucks are nowhere near the same. For more than 18 years, Toyota has built two different lines of compact 4X4s. The one version destined for North America and the one version for everywhere else in the world. One surprising fact is that the Hilux kept using the soild front axle through 1997 before switching to IFS. Even more suprising is which IFS was used. Not the Tacoma coil spring system, but the older torsion system found on North American Toyotas built from '86 through '95 In fact the entire frame and suspension of the current generation Hilux is identical to the '86 through '95 North American Toyotas. Since the mid 1980s, the Toyota 4X4 compact pick-up has been split into two different models. The first is generally known as "pick-up" or "truck" as no model name has been attributed to it since the early 1980s, until the introduction of the Tacoma. This model is destined for the largest automobile and truck market in the world. The United States and Canada. The other model, the Hilux, was destined for every other market in the world. The reason for the differences in these two model has mainly to do with which customer the truck is generally marketed too. In the United States and Canada, the Toyota pick-up is marketed to the general public. In a society where work trucks are almost exclusively the full sized domestic models, Toyota didn't even attempt to break into the commercial market in North America, until the advent of the T-100 pick-up in the early 1990s. However, overseas, in almost every other market, the Hilux is marketed as a commercial truck, for commerical use. This means that the Toyota Hilux truck is generally used as a farm and industry work truck. The Toyota Hilux is ideally suited for this role. With basic half ton models as well a 1 ton models being available. Where an even larger truck or payload was needed, customers could opt for the Toyota Landcruiser 70,75 and 78. As a commercial truck, different considerations were given to the design of the Hilux. While both trucks are very similier, including the same frame, suspension, engines, etc, what differs, is when the truck underwent a design change and what the design change was. Through 1985, both the North American model and the Hilux were very similier. Both models had the same frame and solid front axle suspension. Both models used the same engines, although the diesel engine was rarier in the North American market. The Hilux differed in one major aspect. It included an optional 4door body style that the North American market would not see until 2000. In 1986, both models made a dramatic split. Toyota introduced an entirely new front suspension and engine options on North American models, while Hilux models remained unchanged. The North American models introduced a turbo 22RE and dropped forever, the diesel engine as an option. But the most striking and disappointing change was the introduction of independent front suspension. This demonstrated the difference between the markets the two models were destined for. In the North American market, Toyota assumed that a better ride, better handling and more comfort would increase sales to the general public. IFS did just that. It improved handling, improved the ride, and surprisingly, it improved sales. The Toyota pick-up became one of the most popular, best selling compact trucks in America. But that same IFS that improved sales, became extremely lamented by the hardcore off road enthusiests. The IFS limited off road capability due to it's lack of articulation. Another area that the two models differed is that the Hilux offered a factory optional limited slip. An option that was never available on American models. The Hilux remained unchanged. The commercial customer of the Hilux, did not require better handling, better ride or better comfort. They wanted simplicity and strength and off road ability. Something that the soild front axle Hilux provided well. The Hilux frame and suspension, which included the soild front axle would remain unchanged for another 12 years. However, the body style did change for the American trucks in the late 1980s, just as it did on the trucks in America. While the body styles would always look similier, there would always be major differences through the current generation. In 1995, Toyota introduced a completely new model for the North American market. This new truck was a complete redesign, including an all new frame, body, and engine options. Virtually nothing remained of the old truck. It was called the Tacoma and was not only exclusively a North American market truck, but was exclusively built in Fremont, California. The new truck was powerful and well designed, but it continued with the marketing philosophy that a better riding and handling truck was more important to American customers than brute hardcore off road capability. While IFS was retained, it too, was also completely redesigned. Instead of the very stout, strong double wishbone, torsion bar suspension with ball type steering, the new system used a weaker double A-arm coil sprung system with car like rack and pinion steering. While this system proved to be extremely comfortable on the highway and improved handling, off road durability was slightly compromised. Especially with the rack and pinion steering which would tend to wear out after lots of off road use. However, the demands of off roading customers was not completely lost on Toyota when they designed the Tacoma. Toyota introduced an electric rear locker on some models. It was this option that actually pushed Toyota over the top in the American truck market. Making the Toyota Tacoma the most capable factory off road truck in the North American compact and mid-sized segment, due to it's rear locker and larger optional tires. |

With the Hilux, Toyota again left it relatively unchanged from 1986 through 1997, except for body and interior changes. Only in 1998, did Toyota make any major changes to this model. Despite still being a primarily commercial and farming truck, Toyota saw the success of the '86-'95 North American market Toyotas and wanted to implement that success into it's new Hilux. But Toyota also knew that it's primary customer, industry and farms, wanted to retain the same strength and simplicity of the old Hilux. Toyota compromised. The jigs and machinery were already in place, in Japan to continue to build the original IFS frame. The same frame and suspension found on the '86-'95 American models. So, Toyota elected to use that frame and suspension for the new Hilux and not use the frame and suspension of the Tacoma. The original IFS, while lacking in articulation, was specificly designed for durability off road. The torsion bars were mounted high and out of the way. The A-arms were stout and heavy duty. The steering used the same recirculating ball that the solid axle steering used, and used simlier sized tie rods. To improve durability, much of the steering was located behind a skid plate. The system was well suited for farm and industrial use. And it was the perfect compromise for Toyota who felt that at least some Hilux customers would appreciate the better highway comfort and handling. But one of the most important reasons for selecting the older suspension may be surprising. The frame of the older truck was far more durable than the new Tacoma. The older truck has a fully boxed, internally gussetted frame that is capable of up to a 1 ton load capacity with minor modifications, including different springs and full floating rear axles. The Tacoma, and even the bigger Tundra, is only rated for 1/2 ton on all models and offers no 1 ton model. One reason is likely the weaker only partly boxed frame. Most of the Hilux's customers are industry who demand high payload capacity. A great number of Hilux's sold are of the 1 ton capacity type. In the United States, the last Toyota that was 1 ton capable was a version of the 1998 T-100. The T-100 uses the same suspension and frame as the current generation Hilux, only wider. The current generation Hilux, first introduced in 1998, has body panels that are very similier to the North American Tacoma, but rest of the suspension and frame are indentical to the North American market '86-'95 Toyota 4x4. For engines, Toyota does offer the same 2.7 4 cylinder that is standard in the Tacoma, as optional in the Hilux. But the diesel motors that very popular in the Hiluxs of today, nowhere to be found on any North American market Toyota. |
