Hybrid Autos Toyota Prius

2nd-gen Toyota Prius (US)
The Toyota Prius is a hybrid electric mid-size car developed and manufactured by the Toyota Motor Corporation.

The Prius first went on sale in Japan in 1997, making it the first mass-produced hybrid vehicle. It was subsequently introduced worldwide in 2001. The Prius is sold in more than 40 countries and regions, with its largest markets being those of Japan and North America.

According to the United States Environmental Protection Agency, the 2008 Prius is the most fuel efficient car sold in the U.S.

According to the UK Department for Transport, the Prius is tied as the third least CO2-emitting vehicle on sale in the UK and there are eight cars which are more fuel-efficient than it for the combined use cycle.

As with many of Toyota's vehicles, the Prius has become a standard-bearer in its segment. While many automakers have yet to even develop a gasoline-electric hybrid vehicle, Toyota is already on its second generation of the Prius. This four-door hybrid has become a hit with consumers because of its stellar fuel economy, relatively uncompromised driving and acceleration characteristics and reasonable price.

The 2008 Toyota Prius ranks 9 out of 23 Affordable Midsize Cars. This ranking is based on our analysis of 40 published reviews and test drives of the Toyota Prius, and our analysis of reliability and safety data.

The Prius ranks solidly in the middle of the pack when considered as a hybrid or as a midsize sedan. The Prius's ranking is based on its industry-leading fuel economy, combined with a spacious interior and a standard equipment package that make it competitive as a midsize car, not just a hybrid. However, its styling continues to divide reviewers even after nearly five years on the market, and it sacrifices performance in the pursuit of fuel efficiency. In our hybrid rankings, the 2008 Prius falls behind its corporate cousin, the 2008 Toyota Camry Hybrid, as well as the 2008 Honda Civic Hybrid. Those vehicles don't achieve quite the level of fuel efficiency that drives the Prius's fame, but they also do not suffer some of the performance compromises the Prius makes in pursuit of fuel economy. Little has changed in the Prius for 2008, a car which has not had a major redesign since 2004. One important change for 2008 is the introduction of a "standard" trim which lacks features like heated mirrors and cruise control, but is available at a lower cost than the "base" trim level.

Toyota Tundra

The Toyota Tundra is a full-size pickup truck sold by Toyota that originally went into production in 1999 (as a 2000 model year model), replacing the Toyota T100. The Tundra had a more American look and feel and ultimately had something the T100 never had, a V8 engine underneath its hood. The Tundra was nominated for the North American Truck of the Year award and was Motor Trend magazine's Truck of the Year in 2000 and 2008. As of 2007, the Tundra (now in its second generation) holds 17% of the 1/2 ton full-size pickup market beating the GMC Sierra in monthly sales, but still behind the Dodge Ram, and the best-selling Ford F-150 (in overall sales). The newest Tundra is assembled in San Antonio, Texas, and Princeton, Indiana (where the original Tundra was solely constructed).

The first generation Tundra had many similarities with the old Toyota T100 and the smaller, more popular Toyota Tacoma. The biggest of those similarities was the use of the 3.4 liter V6 engine which was the top of the line engine in both the Tacoma and T100, while it became the base engine within the Tundra. The then new Tundra had an optional 32 valve 4.7 liter V8 powerplant which ultimately became the most desired engine of choice. The first generation Tundra also became the model upon which the original Toyota Sequoia full-sized SUV was based. The two vehicles shared a host of parts and accessories including the 4.7 liter V8 engine, wheels, tires, transmissions and interior components among them.

Publicly introduced in May 1999 as a 2000 model, the Tundra prototypes and "show trucks" were initially known as T150s. However, Ford and automotive pundits felt that this name was too close to the market-leader Ford F-150, and following a lawsuit by Ford, the production truck was renamed the Tundra (Toyota claimed they never truly intended to use the T150 name in actual production). Toyota then countersued Ford regarding the name of their then-released Lincoln LS sedan, arguing it was too close to that of the Lexus LS.

The Tundra was slightly larger than the T100, but still suffered the perception of being too small and carlike to pose a serious threat to the domestic pickup trucks. With a production capacity of 120,000, sales were double the rate of the T100. The Tundra also had the largest initial vehicle sales for Toyota in its history (up until that time). It garnered impressive honors, including Motor Trend's Truck of the Year award for 2000 and Best Full- Size Truck from Consumer Reports. Built in a new Toyota plant in Princeton, Indiana, with 65 percent domestic content, the Tundra showed that Toyota was serious about closing the gap on the Big Three.

Engine choices available in the Tundra were a 24V 3.4 liter V6 engine that produced 190 horsepower (140 kW) and 220 ft·lbf (298 N·m) of torque and a 32 valve 4.7 liter V8 engine that produced 245 horsepower (183 kW) and 315 ft·lbf (427 N·m) of torque. A Toyota Racing Development (TRD) derived supercharger was already available for the 3.4 liter V6 that bumped horsepower to the 260 horsepower (190 kW) range and 260 ft·lbf (353 N·m) of torque range, but TRD introduced a supercharger for the V8 engine late into its second year of production that pushed the V8 numbers to the mid 300 horsepower (220 kW) range and torque to the 400 ft·lbf (550 N·m) range. Although the V6 supercharger is still widely available, the V8 supercharger is rarer and harder to find because of TRD stopping production of the device because of issues of its compatibility with the engine.

The grille was updated for 2003 and the Double Cab version was added to the lineup in 2004. The Double Cab model was a true crew cab with four normal doors, with interior and exterior details copied from the Toyota Sequoia. Its bed is nearly 5 inches (130 mm) longer than the competing Nissan Titan or Ford F-150. It is also 13 inches (330 mm) longer and 3 inches (76 mm) taller than the Regular and Access cab versions. A new engine was introduced in 2005: a 4.0 liter V6 rated at 236 horsepower (176 kW) and 266 ft·lbf (361 N·m) of torque, and the existing 4.7 liter V8 was updated with Toyota's VVT-i variable valve timing technology and was rated at 271 horsepower (202 kW) and 313 ft·lbf (424 N·m) of torque. The 5-speed manual gave way to a 6-speed manual, and a 5-speed automatic replaced the 4-speed. With a towing capacity of just 6,800 lb (on the Double Cabs) and a 7,100 pounds towing capacity on the Access Cabs and Regular Cabs with a V8 engine, it still did not have enough muscle to compete with the heavy-duty offerings of the Big Three and Nissan. Domestic truck aficionados still derided it as a "7/8 scale" pickup.[

Toyota RAV4

The Toyota RAV4 (pronounced "rav-four") is a compact crossover SUV built and marketed by the Toyota Motor Corporation. The car was introduced in Japan and Europe in 1994 and sales began in North America in 1996 to cater to consumers wanting a vehicle that had most of the benefits of SUVs, such as increased cargo room, higher visibility, and the option of full-time four-wheel drive, along with the maneuverability and fuel economy of a smaller car. The early success of the RAV4 paved the way for other compact SUVs such as the Honda CR-V, Mitsubishi Outlander, the Ford Escape/Mazda Tribute, and the Subaru Forester. Its name stands for "Recreational Active Vehicle with 4-wheel drive," although not all RAV4s have four wheel drive, which is optional in some countries. In most countries, the RAV4 is the only compact SUV from Toyota. In other markets, it is the crossover counterpart of the FJ Cruiser.

First generation (1994–2000)

The RAV4 was originally based on the Corolla platform, and was offered in both two and four-door versions. In the US, a 2.0 L I4 engine producing 120 hp was offered. Both Front wheel drive and Four-wheel drive were available, and the RAV4 could be had with either a five-speed manual or four-speed automatic transmission. In 1998, the RAV4 was slightly restyled on the front and rear fascias, and a soft-top two-door was made available exclusively in the US market. Horsepower was increased slightly to 127. In 1999, the two-door hardtop was dropped from the American lineup, leaving the 4-door and soft-top models.

One interesting version, the RAV4 EV, was an all-electric 'zero-emission' model offered for sale in low quantities in California. These models came with a 60,000-mile battery warranty, and the vehicles still command high prices on the used-car market. One sold in 2006 on eBay for over US$50,000.

A significant criticism of the gasoline-powered first generation RAV4s, often called '4.1s', was that they were underpowered, and had relatively poor fuel economy via their 3SFE engines that were designed for earlier Camrys and 1987-1989 Toyota Celica GT, 1990-1993 S-R and Z-R, as well as 1994-1999 SS-I. Later generations of RAV4s, the so-called '4.2s' and '4.3s', have addressed this concern. Like most other Toyotas, all RAV4s have earned the reputation of high reliability, and have enjoyed high resale values.

Third generation (2006–present)

2006-2008 Toyota RAV4 Limited (US)

The Toyota RAV4 was completely redesigned for the
2006 model year, on an all-new platform. It still has the 2AZ-FE 2.4 L four-cylinder engine, which now produces 166 hp, up five from the previous year. The North American and Australian RAV4 is also fitted with the 2GR-FE 3.5 L V6 engine as an option. The new RAV4 topped Toyota SUV sales in the United States for the first time. It is also the first generation of RAV4 to be offered in regular (for Asian and European markets) and extended (for American and Australian markets) versions.

The extended-length RAV4 is larger by 21% in interior volume from the last generation and now has an available third-row seat for two small children (US and Canada only). The RAV4 can still be had in either two-wheel-drive or four-wheel-drive in the United States; however, most countries, including Canada, only sell the four-wheel-drive version.

JDM models are X, G, and Sport. The X and G can be ordered with either front-drive or 4WD. The Sport model with over fender is 4WD only. In Australia, the RAV4 is sold in base CV, mid-range Cruiser, and top of the line Cruiser L trim levels. The extended-length RAV4 is sold in Japan as the Toyota Vanguard.

Currently, the RAV4 is produced in two locations in Japan: Toyota's Tahara, Aichi assembly plant, and under contract by Toyota Industries in its Nagakusa, Obu, Aichi plant. However, when Toyota's Woodstock, Ontario, Canada assembly plant comes online in 2008, models sold in North America will be assembled exclusively there (effective May 2009).

In Malaysia, only the 2.0 automatic variant is available, in a single trim level. This model uses the 1AZ-FE 4-cylinder, in-line 16-valve engine with DOHC and VVT-i. The output for this the 2.0 L RAV4 in Malaysia is at 112 kW at 6000 rpm with a torque of 194Nm at 4000 rpm.
