4 Wheel Drive/SUVs/Does AWD weight reduce acceleration


QUESTION: I am considering buying a car with 188hp. I would prefer AWD (I live in Colorado), but it of course adds weight to the vehicle, in this case 190lbs. My concern is, does that extra weight cause any noticeable reduction in power when accelerating? Thanks

No more than a large passenger would, and you have the advantage of AWD in snow or icy conditions.

QUESTION: Carl, you said no more than a large passenger would (reduce acceleration power). This may be silly to ask, but would a large passenger in fact cause a noticeable loss of acceleration? Thanks again. ps (the vehicle I"m considering is the Nissan Juke crossover).

The reason I use that scenario, is that any vehicle will have a slight feeling of loss of power/acceleration with additional weight added, regardless whether it is a passenger or cargo.  As far as how much, that depends a lot on the car's motor.  Some engines are designed to have torque max out at a low rpm and others at a high rpm, which will make a difference in acceleration.  Horse power is very similar, but reacts more to the top speed of the engine as opposed to torque.
What I would do, is to test drive the Juke solo, then take along a friend or two and actually see if you notice a difference.

Will discuss suspensions, lifts, lockers along with tire suggestions. Trail ratings and possible requirements needed for specific type of trails. Safety equipment and what you should carry with you.

I am not a mechanic, and 4-Wheeling is a hobby, so if I can't answer a technical question it is due to my mechanical knowledge being related to vehicles that I have owned, or have worked on. I do not have manuals on all vehicles, and I suggest that you obtain a repair manual for mechanical problems and do some research before asking your question. Most mechanical questions can't be answered completely without looking at, or listening to the vehicle in person.


40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 1 1/2" suspension lift. This gives me a total lift of 7" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a cold air high flow filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 105:1 in low gear/low range. Other vehicles I own, are a 96 Ford F-250 with a 6" lift, posi rear end, 36" Hummer tires, 5 speed with a fuel injected 460 ci engine, an 87 Samurai with an 8" lift, Ford 9" rear end with a spool, Chevy Dana 44 front end with an electric locker, 5.88 gears, 16% reduction in high range and a 6.5:1 low range with 35" Baja Claws, and a stock 2003 Grand Cherokee Overland. Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.
