2010 Toyota 4Runner teaser - Click above to expand and enlarge

Thanks to a reader tip, Autoblog has obtained documentation confirming rumors that the nearly-here 2010 Toyota 4Runner will get both a four-cylinder model and an optional third row for added utility.

The long-serving body-on-frame SUV finally gets a much-needed replacement for the 2010 model year, and the addition of a four-cylinder model (available only in two-wheel drive) should give Toyota marketers a valuable price and mileage leader, with the latter making friends among consumers and Corporate Average Fuel Economy calculators alike. The displacement of the quad-banger isn't disclosed, but given that its horsepower is quoted as 161 (torque figures were not listed) we assume it's the company's 2.4-liter powerplant. That's a solid little motor, but it will likely have its hands full propelling the body-on-frame 4Runner, which perhaps explains why it will only be available in two-wheel drive form. The V6 model will get 268 horsepower, presumably supplied by the 3.5-liter engine seen in the Camry sedan.

The 2010 4Runner will be available in three model levels: SR5, Trail, and Limited, with the I-4 model only being available in SR5 form. Click through to the jump to see how the specifications for each trim level breaks out.

SR5 models will feature 16- or 17-inch wheels, a dozen airbags (front, side, curtain, and knee), as well as a standard backup and clearance sensor, an eight-speaker stereo with a special tailgate mode, and a telescoping steering wheel. Options will include leather, power seats, the aforementioned third row seating, a power moonroof, as well as audio upgrades, a 400-watt outlet, and Safety Connect (think: Toyota OnStar). The I-4 model will be outfitted like an SR5 V6, albeit without the option for leather seating surfaces and with the inclusion of black fender trim.

Stepping up to the Trail spec will yield consumers some useful off-roading kit, including Crawl Control, protective rock rails, Adaptive Terrain Management System (A-TMS), and a locking rear differential. Other bits include a standard moonroof, sport seats with waterproof fabric, Optitron gauges, an electrochromatic rearview mirror with backup camera, a hood scoop, and a roof rack. Trail buyers will also be able to get such connectivity niceties as a USB iPod interface, Bluetooth, satellite radio, and so on. A navigation system, Safety Connect, and the 400-watt outlet remain optional.

That leaves the full-house Limited model, which doesn't exactly skimp on content. The Limited gets full-time four-wheel drive and Toyota's novel X-REAS suspension system (the purely mechanical system helps to counterbalance vehicle motions like roll and dive). On top of that, the Limited gets 20-inch wheels, a color-matched body kit, dressier aluminum roof rails, turn-signal mirrors, and a moonroof. Inside, the range-topping model also gets leather seating, keyless entry with push-button start, and a JBL audio system.

Upon receiving the 4Runner documentation, we reached out to Toyota for comment, and PR head Curt McCallister gave Autoblog what amounts to a 'no comment' – "Other than the teaser that ran yesterday over PR Newswire, no technical specs have been released on this vehicle yet." Similarly, we have no word yet on pricing, but the 2010 4Runner is scheduled to be revealed at the annual State Fair of Texas late next month, so we should know more soon enough. Thanks for the hot tip, Sprtxkyle!

      finally some common sense, thank you Kowell

      I don't know why a truck needs to scoot to 60 in seven seconds flat or less. A 185hp 2.7L4 should be able to push this truck to 60 in about 10 seconds or so. That was good enough 15 years ago, why not now?
        • 5 Years Ago
        It wasn't good enough for me 10 years ago and it certainly isn't good enough for me now. And a 2WD 4Runner is simply pointless.
      • 5 Years Ago
      Yes. It is outdated. I think I read 2 sources (one of them being C&D) that the I4 is the same as the Highlander's.

      I've had nothing but 4 cylinder 4X4 Toyota Trucks and Tacomas from 1989 to 2004, and they can't be beat. All the 6 cylinders ever did was suck gas and make noise, especially the 3.0. A 2.7 litre 4 banger sounds perfect; I'll be postponing my purchase of a 2009 4 cylinder ext cab Taco to see what this thing is all about, even if it is only 2wd.

      Not every sport-ute needs to win the quarter mile while towing 10,000 lbs.

      /cake, eating it too, etc.

      Toyota is branching out this model to appeal to hard core off-roaders, because the days of the FJ are numbered. Too bad; If I had a corporate gas card, I'd have one of those, too.

      Good job, Toyota

        Big Mola: Based on the 4th Gen 4Runner, I expect that the 5th Gen, 2010 4Runner 4 Cylinder will have a curb weight of about 4000-4200 lbs. In contrast, a 2010 Tacoma Access Cab, 2WD, 4-cylinder has a curb weight of 3560 lbs.

        That's a huge difference, and the performance of the 4Runner will suffer greatly in comparison with the Tacoma.
        • 5 Years Ago

        Things are different from back then.

        First, vehicles weigh more than they did back then, that means they simply require more power to do the same thing.

        Secondly, earlier engines in trucks were designed for maximum torque over HP. Even though you only had 290hp in a later BBC, you did have 410ft-lbs of torque. Modern engines prefer to keep hp and torque figures closer, so even if you have 403hp now in a 6.2L SBC (113 more hp), you've still only got roughly the same amount of torque (415ft-lbs) with a similar torque curve.

        Finally, gearing. Trucks back then were geared for work over gas mileage. My first K5 blazer had a four speed manual with a first gear in the 6:1 range (crawl gear), a second gear in the 3:1 range, a third gear in the 1.5:1 range, and a final drive ratio of 1:1.

        A modern 6L80E automatic has a 4:1 first gear, a 2.3:1 second gear, 1.5:1 third, and a 1.1:1 fourth (with two overdrives). That means, if all other things are equal between the two trucks, the older truck would actually be able to put more torque to the ground in first and second gear (though, it would use more fuel to do so).

        That's why a lot of people want to see 7 and 8 speed transmissions used in modern trucks. They could combine gear ratios for both work and for gas mileage. Without tow/haul mode enabled, the truck could be setup to start in, say, third gear to save gas mileage and appease CAFE. With tow/haul enabled you could have, say, a 6:1 first gear that could get a heavy load moving when you need it, even without a 400hp/400ft-lb tq engine.

      car and driver said it was a 2.7 I-4, not the 2.4, but yeah it'll be pretty slow.
      • 5 Years Ago
      I still stick by my "Meh" comment from yesterday.
        • 5 Years Ago
        I'm kinda impressed by my half star.
        • 5 Years Ago
        i dunno, the Trail edition sounds like its right up my ally. i have 97 that's been "Trail'd" out for Colorado backcountry use and is getting fairly up there in miles (215,000)...

        kinda makes me a bit nervous for my Grand Staircase/Escalante trip in October...
        • 5 Years Ago
        When there's one I can actually see, I may be more impressed. Until then, I just can't really get too excited about it, especially considering Toyota's reputation for suburb-stormers.
      • 5 Years Ago
      Actually, are we even sure that the next generation 4Runner will be body on frame? Unless I missed it, I didn't see anything in the leak that states that it will be.
        • 5 Years Ago
        It's definitely body-on-frame. They already have plenty of SUV-ish crossovers around that size that aren't (Venza, Highlander, RX350) so this is the body on frame truck based offering.
        • 5 Years Ago
        Yes, it is still body-on-frame.
      • 5 Years Ago
      Most 4runners around the world come in four cylinders, albeit with standard shift, and they do just fine, some nice hop up stuff avalilable too, and they get up to 30 mpg, so if you're not carrying a trailer, don't underestimate this powerplant, its just fine, and contrary to a V6, it'll get better mileage as miles pile up!
      • 5 Years Ago
      The I4 is for women to look adventurous while sitting behind someone's brake lights on the way to the mall. It'll do just fine for that.

      • 5 Years Ago
      Wow.....As a 2005 4Runner prior owner I'm uttlerly speechless at how terrible all aspects of this are. If the C&D pics are real (don't see how they couldn't be), and the rumors of the dropped V8 are real, Toyota just lost a sale.

      How could the 5th gen 4Runner be sooooooooo UGLY?!?!?!? I mean, this is terrible! It looks like a 4Runner and an FJ Cruiser got drunk, had a mistake, then kicked it in the face with an ugly boot!

      No V8 option - This is too bad. The 2010 4Runner with the 310 HP 4.6L V8 and 6spd seemed like a perfect match! Something is fishy here though, Toyota didn't design a brand new V8 engine just for the Tundra - this engine has to be going into another Toyota truck - my guess is the new Lexus GX. If not that, then there is something else not out in the open yet...
        • 5 Years Ago
        I do expect to see the 4.6 V8 in the GX. Unfortunately, the side-hinged rear door on the GX is a deal killer for me. I greatly prefer the traditional top-hinged hatch on the 4Runner. It works better when you are parallel parked, and it provides some protection from the rain when I'm out fishing on the beach.
      • 5 Years Ago
      Yes, the 4-cylinder will be hopelessly underpowered and will not sell.
      • 5 Years Ago
      3rd Row of Seats...
      ...4 cylinder engine!

      Sounds so last century!?!?
