Hi everyone...

Any engineers/fabricators in Cape Town with some free time that want a project?
A mate of mine was looking at getting a nudge bar made for a 4x4 (yes I know they can be purchased from multiple places and so does he) and was wondering if this would interest anyone?

Will be fairly basic design...

Any takers?
 
Chances are it will be cheaper to just go and buy one off the shelf.
 
There is a major problem in fitting a 'nudge bar' or 'bull bar' to ANY modern vehicle, especially the trend in having them fitted to 4x4's & SUV's.

Motor manufacturers have impact-absorbing bumpers that can absorb small impacts - typically below 8-10 km/h, without transferring the kinetic energy into the vehicle structure, by virtue of a deformable plastic outer skin, and an energy-absorbing foam liner on the inside.

A nudge-bar / bull-bar negates that effect and transfers the impact energy directly into the vehicle's frame, where ever it has been bolted to the structure, meaning that even MORE DAMAGE could actually result in a 'bumper bash', than if the vehicle was left stock-standard.

Another much more important safety-related issue is that various impact sensors are mounted behind the bumper's plastic skin, typically on the vehicle's front radiator cross-member area, which sense a heavier impact at higher speeds - typically above 20 km/h or so, and, depending on the severity of the impact, deploy the airbags fitted to the vehicle (front & side curtain as required) to protect the occupants.

Having a nudge bar / bull-bar means that the sensors cannot accurately measure impact forces, and as a result thereof, may not even register a sufficient impact force to actually deploy the airbags.

This could have serious, and even fatal, consequences for the occupants.


Check out all the negative reader comments in this article, where the owner of a Maruti Suzuki Ertiga had bull bars fitted, for more details.

I very much doubt any pro engineer is going to voluntary time for a person project of a mate of yours.

Nothing against that project...its more a question of where is the incentive? Even opensource / community projects seem better in terms of incentive.
 
There will be remuneration :) either in beer or whiskey... or R's....

I don't think you understand the amount of R's that will be required to make the project worthwhile.... like I said, it will be cheaper to buy a product off the shelf.

I'll pass on the message! Thanks everyone! Happy Festivities!
 
2015 Suzuki Jimny: Five Reasons Why It's The Ultimate Adventure 4x4

The 2015 Suzuki Jimny has received a mild facelift, which is a great excuse to for us to gather 'round the campfire and admire this delightfully darling little 4x4.

Though it may be small, I posit it just might be the ultimate adventure off-roader.

It's small and light. Off-road rule number one: "less is more." Whatever you can't crawl over, you can probably get around. Or through. If you do get stuck, you and your travel buddy won't have much trouble winching out of anything when your truck only weighs just over a ton.

It's simple. The "better" ones have traction control now. Other than that, you can basically still fix it with plyers and vice grips.

It's incredibly efficient. Even if you can't hit the 40 MPG average claim in the dirt, you're going to be using a lot less juice than a Wrangler... or pretty much any other 4x4 in America for that matter. And you still don't have to put up with the rabble and lack of refinement you get with a a diesel.

It's cheap. A Troller T4 is like $40,000 in Brazil, and that's about where a good Wrangler winds up here in the US. A Jimny? Try half that.

Less power means more fun. It's common sports-car enthusaist ethos to reckon running '89 Honda CRX to the limit on your local backroad is more fun than holding the reigns on a a McLaren P1... trying desperately not to get killed or arrested getting the most out of the car.

I offer the same can be said for off-roaders.

Sure, walking a Range Rover through a course with one hand on the terrain-selector and another on your iPhone is kind of fun... but it's nothing approaching the satisfaction you'll get working hard for every obstacle, which you'll be doing with 60 horsepower.

The Jimny, in one form or another, has been squeaking around since 1998. Though it's currently sold in 188 markets, sadly America is not one of them.

The one pictured here is the British version, which you can buy for about $20,000 (the high-trim automatic version starts at $23,000).

Weighing around 2,400 pounds, the 2015 Jimny is 145" long, 67" tall, and just 63" wide making it 3' longer than a Smart car and about a foot shorter than the current JK Jeep Wrangler two-door.

Even with just 7.4" of ground clearance, the Jimny's so stubby it still gets a 34º approach angle, a 31º ramp breakover angle, and a crazy-steep 46º departure angle.

It's no speed demon though... and probably won't be able to do much with big tires.

A 1.6 liter gasoline engine burps out just over 60 horsepower at a screaming 6,000 RPM, with 81 ft-lbs of torque on tap at 4,100. Suzuki reports a top speed of 87 MPH, but just shy of 40 MPG on average with a manual transmission.

Oh yeah, so what's new for 2015? Some fancier seat fabric, a few new dash lights, and traction control in more models. Who cares, I really want one.

Come back, Suzuki... we'll be good to you this time! (No, we probably wouldn't. Damn the US auto market and it's demand for super-sizing.)
