The biggest change is the offering of a new standard 4.6-liter V8 engine, which makes more power and delivers better fuel efficiency than the previous standard 4.7-liter V8.The previous 4.7-liter engine made 276 horsepower and 314 pound-feet of torque, and the new 4.6-liter engine makes 310 horsepower and 327 pound-feet of torque.The new engine is also matched with a six-speed transmission instead of the previous five-speed and, as a result, EPA highway fuel economy for a Sequoia with two-wheel drive has been increased from 17 mpg to 19 mpg Highway.

In addition to the new engine, all 2010 Sequoia models have driver and front passenger knee airbags, a Cold Kit with heated side mirrors and windshield wiper de-icer, and daytime running lights.And many optional features and amenities have been made standard equipment.This means there are few options to order, customer value has been enhanced and ordering and purchasing the vehicle is much easier.

This second-generation Sequoia is bigger and more capable than the original version.It's the biggest SUV Toyota has ever made, and it has the most capability.The Sequoia can transport eight people, plus cargo.The interior is designed with generous seats, big armrests, and lots of storage for passengers, plus an optional entertainment system for long trips.

The Sequoia can be equipped to tow trailers of up to 10,000 pounds.Its optional 5.7-liter V8 makes more than 400 pound-feet of torque, while the six-speed transmission allows for smooth cruising.Four-wheel-drive models offer credible off-highway driving capability, with easy shifting into and out of 4WD, good low range gearing, and lockable differential for better traction.

A comprehensive combination of electronic safety, stability and traction controls, Toyota's STAR system, is standard on all models, as are advanced airbag systems.

The Sequoia represents a state-of-the-art rendering of the modern sport utility vehicle.It's built to transport people and their gear, in comfort, across long distances on North American super-highways.It's all about getting people in and out easily, keeping them comfy, and making heavy loads secure and routine.It rides quietly, steers easily, and with three models, two drivetrains, and a full complement of features, the Sequoia can meet a variety of wants, needs and price points.

The Sequoia differs from the premium Land Cruiser in that the Sequoia is larger, can carry and tow more and is designed specifically for North America.The Land Cruiser is a more upscale luxury vehicle with greater off-road capability, important in global markets.The Sequoia is more about practical utility and comfort.It is built at Toyota's Princeton, Indiana, factory and shares many components with the Tundra pickup that is now built in San Antonio, Texas.

The Toyota Sequoia is packaged in three grades: SR5, Limited and Platinum.Sequoia SR5 comes standard with the 310-horsepower 4.6-liter V8.Limited and Platinum models have the 5.7-liter V8 (optional on the SR5).All have the six-speed automatic.Eight-passenger seating is standard; the Platinum seats seven, with its luxurious second-row bucket seats.A flex-fuel version of the 5.7-liter engine that can run on E85 (85 percent ethanol) is available in most states.

Sequoia Limited ($48,640) comes standard with the 5.7-liter V8 and adds heated, leather trimmed seats; upgrades the driver's seat to 10-way adjustable; and adds leather trim to the steering wheel, seats, and gearshift knob.The rear 60/40 third-row seat is power operated.The dash is upgraded with brighter Optitron gauges and a multi-information display, and a 14-speaker JBL Synthesis audio system includes Bluetooth capability.Outside, the Limited adds a roof rack, fog lamps, running boards and parking sonar system.The Limited is available with four-wheel drive ($51,865).For 2010, new standard equipment for the Limited includes a power rear door with a sliding window, 20-inch alloy wheels power tilt/slide moonroof, rear spoiler, and a backup camera with a 3.5-inch display built into the rear-view mirror.

The Platinum ($55,680) comes with 20-inch alloy wheels, a rear load-leveling suspension, and a memory feature for the power seats, which are heated and air conditioned in the front.Second-row seats are heated buckets, converting the interior to seven-passenger capacity, and a navigation system with backup camera is standard.Exterior features include a power back door, moonroof, and headlamp cleaner.Also standard on Platinum are laser cruise control, a rear-seat DVD entertainment system with a seven-inch screen and a separate rear-seat audio system, including wireless headphones.There is also a new wood-trimmed steering wheel and shift knob.The Platinum is available with four-wheel drive ($58,905).Options for the Limited include the rear-seat DVD entertainment system ($1,670), and navigation ($1,460).

Safety features standard on all models include advanced frontal airbags, seat-mounted side-impact airbags for the front row, side-curtain airbags with rollover sensor, Vehicle Stability Control (VSC), traction control, and ABS with Electronic Brake-force Distribution (EBD) and Brake Assist.

The low windshield angle accentuates bulk below the hood line, and large high-mounted headlamps add an alert look to a cabin-forward design.Exterior mirrors are large, because they have to be, but careful smoothing has reduced wind noise, as does the use of partially hidden wipers that likewise must be very large to sweep the large front windshield.The design has a drag coefficient of 0.35, respectable for a full-size truck.

From the side, large, strong-looking door handles are apparent, the kind you'd appreciate if you wear gloves.The rear doors open wide, for easy child seat and passenger access.Parking sensors enable easier parking and the ability to avoid people or toys lurking in the driveway.

The Sequoia boasts a large cabin.The interior is conspicuously wide and offers ample legroom and shoulder room.The dash is simple and focused, with two central gauges, speedometer and tachometer, flanked by fuel, temperature and voltage gauges.Bright rings accent the instrumentation.

A very large rectangular shifter dominates the metallic center strip area, and behind it is a wide central console designed to hold 12 CDs or four DVD cases.The four-spoke steering wheel contains controls for AC, Bluetooth-capable phones and audio functions.The steering column tilts and telescopes.

Switches and dials are used to control windows and the HVAC system.The HVAC system is designed to define and maintain three different climate zones, two in the front, and one in the back.We think Toyota does a good job when it comes to switch feel and operational consistency of dials and other touch points.

Two overhead compartments are suitable for sunglasses, and the control strip has sunroof controls.An electrochromic rear view mirror is standard except on SR5, and the mirror contains built-in garage door opener buttons operating on three different frequencies.

The sun visors are huge, and they slide on their hangers, providing effective shade for driver and passenger all day long.On the A-pillar are hefty grab handles, with grips big enough to support body weight as you swing into the seat.

The interior is notable for thoughtful features that increase utility, such as a compass, map light, automatic up-and-down jam protection for front power windows, and back door power window.There are eight cup holders, eight bottle holders, console surfaces, everything you would want for eating in the Sequoia while putting away the miles.And then, there's lots of door pocket space for trash.

The Sequoia is especially designed to make the third-row passenger seats more comfortable, and more useful, more like real seating for adults.To that end, the third-row seats have almost as much leg room as the second-row seats, and have adjustability features rarely seen in eight-passenger SUVs.For those who often make use of the third row, the Sequoia's standard interior layout is better than many SUVs we've seen, in which the third-row seats constitute emergency seating for smaller people only.Those who do not need eight-passenger capacity can configure the Sequoia with captain's chairs in the second row, which shifts the priority to second-row passenger comfort.

The Sequoia is one of the very few SUVs with a retractable rear hatch window.It also has a closed, removable ashtray that is dish-washable, and a cigarette lighter up front.

Last but not least, the Sequoia has ample cargo room behind the third row, and even more if you fold it down.When the seat is folded flat, large baggage or cargo can be loaded without removing the seat.It is a well-organized cargo area, even having tow hooks that can hang grocery bags.The seat folds flat manually in SR5's, and upgrades to a power folding feature in Limited and Platinum models.

In everyday driving, the suspension is surprisingly compliant for a vehicle built to carry heavy loads.There is a minimum of tummy jiggle on broken surfaces, and yet, when hard braking is called for, the front end does not dive wildly or pitch about.The Platinum version has the active air suspension, which has the ability to maintain more even ride height with heavy loads, which we tested and found it works well.Without a load or a trailer, we couldn't tell much difference between the suspensions.The standard setup is an independent A-arm configuration at all four corners, with coil springs and anti-roll bars.

The 5.7-liter V8 has lots of power, with an impressive reserve of torque.We loafed along at 2000 rpm or less all day long without feeling the need to punch the throttle.The 5.7-liter makes most of its torque below 3600 rpm, so when you do decide to pass, acceleration is impressive.The 5.7-liter is ULEV-II compliant, meaning it emits very little pollution (Ultra Low Emissions Vehicle).It features four valves per cylinder and variable valve timing on both intake and exhaust valves, and a low-friction valve train enhances efficiency.Consistent with the internal component quality is the exhaust, which is made from stainless steel and has four catalytic converters.

The 4.6-liter V8 also has four valves per cylinder and variable valve timing on both intake and exhaust valves.It is not as strong as the 5.7-liter engine, but it delivers a level of power that should be more than adequate for any owner who doesn't have to tow heavy loads.

The six-speed electronically controlled automatic transmission accounts for part of the Sequoia's decent highway mileage.The transmission is controlled by a shifter that allows sequential shifting, and has a lock-up torque converter for better towing efficiency and heat control.There is a Tow/Haul mode that changes the shift points for heavy loads and long, uphill grades.

Four-wheel-drive models come with a two-speed transfer case with 2.6:1 Low range.We found Low range easy to get in and out of, even on ground that was not perfectly level.And the gearing seemed low enough that the Sequoia could crawl at speeds slow enough to slog up very steep terrain.

Towing capabilities are in the class of a full-size pickup.The Sequoia can tow up to 10,000 pounds.A seven-pin connector and a standard four-pin connector are set up and ready to use, and there is a pre-wired brake controller connector under the dash, similar to the Tundra.The Max Gross Combined Weight Rating, the total permissible weight of vehicle and trailer, is 16,960-17,280 pounds, depending on equipment.

The brakes are consistent with full-size pickup capability.Very large discs are mounted on all four corners.The brakes feel reasonably gradual, with some forgiveness at the top of the pedal and very strong response as foot pressure is increased.The brakes are enhanced by ABS (anti-lock brake system) and Electronic Brake Force Distribution (EBD), the latter of which keeps all four brakes accurately proportioned as the vehicle stops, assuring straighter stops and better control and shorter stopping distances.Brake Assist reduces stopping distances in panic situations.These are all useful and necessary features for a modern SUV, particularly one that might be towing a boat or RV.

We still have a hard time trusting laser cruise control, but after a day in the Sequoia it got easier.We suspect dynamic cruise control is one of those features that we'll all rely on before the decade is out.We switched it on and watched it work, carefully, and, sure enough, it sensed vehicles as we came up on them, slowed appropriately, and maintained the distance we selected.Then, when the lane opened, it slowly resumed speed.It's not really intended for use on a crowded highway, but it's useful on open highways with low traffic.

In daily use around town, the Sequoia will seem big to those not accustomed to maneuvering full-size domestic iron.We notice that, like any full-size, the hood is long and tall, and the distance to the rear bumper is not easily estimated without practice.

Parking sensors front and rear go a long way toward making the best of the need to fit a big SUV into an average parking space by providing audible warnings when maneuvering in close quarters.

The rearview camera that displays a video image of what's behind you on the navigation screen is even better.We highly recommend getting this optional feature for its safety benefits.A rearview camera, in addition to the audible warnings, can help alert the driver to a child behind the vehicle or, more commonly, unseen objects you don't want to hit.It also makes the parking process easier and speedier.The camera also helps greatly when hitching a trailer, eliminating the need for trial and error or a spotter.

Steering is fingertip-easy around town.The turning circle is just 39 feet.It avoids being boat-like by a variable system that adds more return-to-center and a firmer, more precise level of control as speeds increase.At higher speeds, we found the Sequoia easy to keep in its lane without undue attention.While this family SUV is not built to be a cornering machine on country roads, control is good enough for confident handling.The steering column actually has a floating shaft that keeps noise and vibration from coming through to the wheel.

On a vehicle this big, power windows and doors are more than just luxury options; they become necessities.It's an impossible reach across the cabin, and a long walk to open the tailgate in the rain.The power rear hatch can be opened using the remote fob, handy when approaching the vehicle in a downpour with a load of groceries.
