Interseting Mazdaspeed 3 tech
from this article http://carsguide.news.com.au/story/0...-21822,00.html
It runs the same turbo-charged 2.3-litre Direct Injection Spark Ignition (DISI) four cylinder as the larger Mazda 6 MPS. Where the 6 runs an all-wheel-drive layout, the 3 is a front-wheel-drive with devilishly smart torque management cutting out almost all traces of torque-steer.
Sensors detect if the driver has too much steering angle wound on and subsequently the throttle openings are controlled along with wastegate torque, giving what essentially is unobtrusive traction control.
Sensors detect if the driver has too much steering angle wound on and subsequently the throttle openings are controlled along with wastegate torque, giving what essentially is unobtrusive traction control.
The first expectation with Mazda bolting in the perky 2.3-litre DISI four cylinder with the same power and torque levels as the bigger 6 MPS and hooking up a turbocharger is that the end result would be a torque-steering monster. Not the case.
Part of the reason rests with the torque-sensing limited slip differential similar to what is used on the MX-5 and RX-8.
The whole driving experience is smoothed out by boost pressure control which keeps the lid on sudden torque spurts.
This is achieved via sensors that detect steering angle in first and second gears which almost completely eliminates any torque steering behaviour.

it arrows from 0-100km/h in a cracking 6.1secs which is quicker than some locally produced and acclaimed V8 sedans. It is also .5sec quicker than the Mazda 6 MPS.

Some car company needs the cojones to come out with a small hotrod car similar to the Mazdaspeed 3/Cobalt SS/Ion Redline/Civic SI but with an RWD layout. A little car like that + RWD + solid power = my money (if well executed).

RX8 and a Truk....
IIRC the SRT 4 ran mid 5's to 60...right? I remember the new Caliber SRT4 is 'less than 6 seconds' to 60.
Rhawb - look for the Focus with the Mustang Cobra SC V8, and rwd conversion

I think cares like this are intended for two markets: ricers who can't afford faster versions (Evo/STi) and family men who are forced to buy a cheap sedan, but want some get up and go power. I don't think they are intended for people with a preference for handling over power.
Moreover, if companies do spend the time/money on redesign they're likely to throw in AWD rather than RWD because of the perceived benefits: it'll seem more like an Evo/STi to ricers and safer to the family men in bad weather.

True, I'm just thinking along the lightweight/high power lines - kind of like a poor man's Elise. Maybe even make it its own model, just develop it alongside the FWD car to save some bucks. (not sure if that would actually save any cash, though)

What's it looking to weigh and what kind of power is it going to put down? I remember they were saying no rotary, but if they toss that MS6 engine into it, I think it could be piles of fun. I could probably just search it, but I'm lazy and we're already talking about it
Oh, never mind - just found it. 180 hp and 2500 lbs should make for lots of fun. Boost it up or something and you've got lots and lots of fun.

weight is targeted less thn the miata. power- dont know as it hasnt been finalised yet but 180 was talked about and190-210 with a DSI MZR 2.3 is not out of the question na. of course 250 plus fitted with the factory turbo of the Mazdaspeed cars. 238(ish
) with the Renesis. it still could get scrapped and not make it to production. go to the kabura forums or rotary news thread and make sure you post a "please build it" message. we'll know in a year or so as it should debut by mid 2008 if they green light it. my opinion is they already have greenlighted a kabura based vehicle (based on the fact that they have shown the kabura around the world which they didnt do with the other concepts this past year) and that we'll see a prototype with a new name, like rx-evolve to rx-8, at detroit in february. likely to be mx-3 if piston and rx-3 if the rotary option is available.

Blast! I just wish it could be done by the time my lease will be up. (next year) Oh well, I'll tool around in a cheap pickup or something until they release it

$40,000 !?!?! Are you kidding, I was NOT expecting that to be the price, is that for real?? I started a thread on that car a while back and said how badly I wanted it, but man I had no idea the price was gonna be that high.

back to topic for a moment- i think this is a smart way to do it personally- its not gutting the power but modulating its increase as needed to reduce the t steer. i think its brilliant
