Toyota Sequoia engines
Content
Toyota Sequoia (Toyota Sequoia), both the first and second generation are full-size, the largest SUVs after the Mega Cruiser. The debut of this large car took place in 2000 as the next year's model. In terms of price, it was above the mid-size 4Runner, but below the Land Cruiser.
Moreover, the Sequoia replaced the Toyota Tundra, on the basis of which it was built. Currently, it finds demand in the markets of the USA, Canada, Mexico, Puerto Rico, the Middle East.
The time of production and sale of the first generation of these machines was the period from 2001 to 2007. Since 2003, the car has been equipped with:
- on-board computer control system;
- climate control;
- multi wheel.
The design of the front suspension is similar to the Prado 120, the rear suspension is similar to the Land Cruiser 100. With the help of dual-zone climate control, you can adjust the flow to the rear passengers and ventilate the trunk.
The third row seats are easily removed and installed in place, and the second row folds in the direction of the car, greatly increasing the luggage compartment.
Both generations of these machines were designed and built for the North American market. Although the company in 2010 announced the removal of this SUV from the assembly line due to a decrease in demand, at the same time the engine was replaced with a larger and more powerful one. The five-speed automatic transmission was also replaced with a 6-speed one. Power was plentiful for the rear-wheel drive version, and the large SUV hit 100 km/h in just 6,1 seconds.
What engines were installed on different generations of cars
This large Toyota Sequoia SUV was equipped with three types of engines with impressive performance, the main ones are listed in this table:
| Generation, restyling | Engine make | Volume, l | Power, kWt. | Torque, Nm |
|---|---|---|---|---|
| 1 | 2UZ-FE | 4.7 | 177 | 427 |
| 2UZ-FE | 4.7 | 177 | 427 | |
| 1, restai | 2UZ-FE | 4.7 | 208 | 441 |
| ling | 2UZ-FE | 4.7 | 208 | 441 |
| 2 | 1UR-FE | 4.6 | 228 | 426 |
| 2UZ-FE | 4.7 | 201 | 443 | |
| 3UR-FE | 5.7 | 280 | 544 | |
| 3UR-FE | 5.7 | 280 | 544 | |
| 3UR-FE | 5.7 | 280 | 544 | |
The power unit of the 1st generation Sequoia was a 8-liter V4,7 engine, paired with a 4-speed automatic transmission. After restyling in 2004, the VVT-i variable valve timing system appeared on the engine and it became more powerful - 273–282 hp. with., and the previous gearbox was replaced by a 5-speed.
The second generation of the Toyota Sequoia full-size SUV is offered with either rear-wheel drive or all-wheel drive. The car is equipped with 8-cylinder engines and an automatic transmission.
All internal combustion engines installed on the Sequoia were gasoline. The engines that were on the cars of the first generation spent 100 liters of fuel on a 16,8-kilometer journey if the movement was on a mixed cycle. After restyling in 2004, consumption decreased to 15,7 liters. On the second generation of cars, depending on the brand of engine, the consumption ranged from 16,8 to 18,1 liters of gasoline. Fuel tanks had a volume of 99 to 100 liters.
What engines are most widespread
Engines of the 2UZ-FE brand, represented by several modifications, which affected their power (240, 273, 282 hp), from 2000 to the present, continue to be installed on Toyota Sequoia of two trim levels. It is clear that the total number of these motors installed only on these Toyota models exceeds the remaining two brands of power units.
The power plant of the 1UR-FE brand has been installed on one configuration of this car 2007 AT SR4.6 since 5 and to this day. Its prevalence is therefore the lowest of the three engines.
The middle position is occupied by the 3UR-FE brand engine, which from 2007 to the present time has powered three trim levels of Toyota Sequoia. Perhaps, given the use of these motors on other Toyota models and other manufacturers, the picture may change somewhat.
On which models of the brand were these engines installed?
Along with the Toyota Sequoia, the 3UR-FE engine served as a power plant on other models, details of which are summarized in the table below:
| Engine make | Toyota | Lexus | |||||
|---|---|---|---|---|---|---|---|
| Aristo | higher | Crown | Majestic | soarer | 4runner | land Cruiser | Tundra |
| 1UZ-FE | + | + | + | + | + | ||
| 2UZ-FE | + | + | + | + | |||
| 3UR-FE | + | + | + |
As you can see, all three motors were mainly installed on heavy and powerful SUVs, and showed themselves only on the good side, both in terms of dynamic qualities and reliability.
Which engine is better to choose a car
It depends on personal preference and availability of money. On the other hand, the choice is difficult due to the high reliability and efficiency of all three motors. What are their technical differences?
Since 1997, the VVTi system has appeared on the 1UZ FE, which made it possible to increase the diameter of the intake valves. A different gasket was installed on the cylinder head, an ACIS intake manifold was used. Improved ignition system, pistons and installed electronic throttle. After restyling, the compression ratio and engine capabilities increased.
This motor is valued for the strength of materials, which increases the resource. For example, 1UZ FE aluminum silicon alloy pistons are resistant to high temperatures, which ensures tight tolerances and a tight fit to the cylinders. The 2UZ series of engines turned out to be successful, without design miscalculations and shortcomings. Resource 2UZ-FE - more than 0,5 million km.
The cast-iron cylinder block increased the reliability and durability of the motor.
In 2005, the VVTi system appeared on these engines, which affected the power, which increased to 280 hp. With. Motors of the 2UZ series are equipped with toothed timing belts with replacement after every 100 thousand kilometers.
The 3UR-FE engine is distinguished by a large volume, a stainless steel exhaust manifold, the presence of 3 exhaust purification catalysts, etc. It is produced both with a turbocharger and in an atmospheric version. Along with gasoline, it is not difficult to convert them to biofuels or gas. This motor, with proper maintenance, will have excellent reliability and endurance. According to some reports, he is able to go 1,3 million km without major breakdowns.
