Is this a Canadian car? A friend of mine has one and he says there is a V 8 under the hood (which I can't believe).

Asuna was made by Pontiac. I believe it looked the same as the Isuzu Impulse.
Pontiac used the name as they thought consumers would think "Japanese" or "foreign". They didn't last long and no they didn't have a V8. I think they used a 4 cycl, but perhaps the V6 found in the old Chev Z24 & Sunbird

Thanks. I didn't see the engine myself but he said he saw V 8 written under the hood. Said it was quick too.

I can't remember too much on them but they were troublesome...

One of my friends had a 4cyl one...



It's the Isuzu Impulse cousin.... but the impulse had AWD also....

asuna was sold through the pontiac dealer for a couple of years. they had 2 models, sunfire (isuzu impulse) and the sunrunner(susuki sidekick).it stop after 2 years and became geo.
sunfire was a 4 banger, though the isuzu had an AWD version with a turbo eng which was sold up here in canada in GM dealers.

Do you remember seeing those ASUNA commercials in the theatres? The ones where they had: a soon na. The whole theatre would by saying it. LOL.

Anyhow, just to add my $.02 the Isuzu ones w/ the turbo and AWD drive also had a fancy Handling by Lotus badge.

Anybody remember the Imark? They also had the same badge.

The Isuzu Impulse RS (AWD, turbo, Lotus tuned suspension) was a pretty cool car on paper that Isuzu/GM pretty much neglected. They didn't import many (below 1000 units to NA from what I recall) and I think they only imported them for one year, 1991. Anyways, its AWD system consisted of a centre and rear viscous clutch limited slip coupling with torque split being around 43/57 front/rear. The front diff was, I believe, open. It had a turbocharged 16 valve 1.6L inline 4 engine with air/air (I think) intercooler putting out 160 HP and 150 lb-ft torque with a redline of 7200 RPM. The much touted Lotus tuned suspension is standard on all 89+ Isuzu cars but was considered a stepback from the pre-Lotus suspension cars. Originally, a German company that did Opel suspension tuning was contracted out and they came out with a really stiff and well handling package rumoured to hit >0.90 g's on the skidpad. They introduced it to Japan only till about 87 when Lotus was contracted to do the suspension work when GM acquired them. During the Lotus development, the 87-89 RS was released with a suspension package that was nearly the same as the German tuned one intruduced in Japan. When the 91 Lotus tuned suspension was standard on the RS, it appeared that Lotus softened the spring rates and bushings resulting in vague handling characteristics at the limit and a lot of body roll. Still, C&D recorded a 0.88 g skidpad. Apparantly, GM had its hand in all of the suspension muck and its been rumored that the suspension was softened to fit more with American markets and the economy market the Impulse was aimed. Anyways, there are people out there who have made the RS into a killer car with Quaife differentials, 300 HP engines, 0.95 g handling but as with anything, money can make even a Pinto fast.

As for the other Impulse/Sunfire cars, they were 1.6L inline 4 engines with 130 HP and 102 lb-ft torque up to 93 where it was upgraded to 1.8L inline 4 with 140 HP and 120 lb-ft torque. There was no V8 option.

Wow Rhung. That's impressive. Did that all come off the top of your head?

IIRC the Impulse was also a rejected mk2 Scirocco design as well.

As a former owner of a '91 Isuzu Impulse XS (FWD version), I can honestly say that the car handled amazingly well near the limit, but once the limit was reached...ass end into the ditch (not that I would have any personal experience or anything like that).

Here in Edmonton, I raced a 900cc bike down the windy part of Groat Road within the first 2months I had it and hit a speed of 140kms/hr. We were going so fast, that I actually beat the bike through that section of road. I used one lane only for this high speed run of death. Bike couldn't lean over far enough to beat me. Amazing handling car, just not enough guts. IIRC, the XS (not turbo RS) version redlined at ~7800rpm with peak hp and torque around the mid 6000's.

Other than the name, the only difference between the Asuna and the Impulse XS was 1.8l 4cyl 16V motor at 140hp and 17" Rims vs the 1.6l 4cyl 16V motor at 130hp with 16" rims. Interior was identical.

BTW, the non adjustable "Lotus" struts for those cars were in excess of $1000 per corner from the dealer (installation NOT included) and one of the reasons I eventually got rid of the car. Couldn't see myself spending $4000+ on new struts on a car that was less than $12000 brand new.

Are you serious Markus? $1000 for ONE strut?

Wowzers...you could pick up some DMS or some other high strung/brand race coilovers for $4000!!

Most of it is at the top of my head. I used to be looking into those cars since the claims were quite intriguing and I stumbled upon a NG that talked quite a bit about them. There was also a tuner shop that did Isuzu ECU programs in Montreal or Toronto (can't remember) that I had a few discussions with. There was a nice looking blue Impulse RS in Edmonton that the guy was asking for 6-7k that I was interested in. However, I got turned off by the limited numbers, cost of parts, and questionable build quality. So ended my Impulse RS journey.

Default This is unreal...

I used to drive one of those too, I did not own it though. It was an blue, intercooled AWD version. What a blast. It had a "factory" uprated suspension which lowered it 1". I've never heard anyone else having that option. It was a blast to drive & pretty quick too. Since it wasn't mine I never pushed it to its limits (my GF at the time liked going fast, just not too fast). I don't remember parts costing that much though they were definitely more expensive to repair than most vehices.
Markus is right. All Isuzu versions got the 1.8L. All Asuna versions got the 1.6L. The Geo Storm is also the same car w/ a differnt skin, I believe it had the 1.8L available. Only the Isuzu version got the turbo AWD. I don't remember any versions getting wheels bigger than 15", I could be wrong. The only weak part of the car was the transmission, not smooth AT ALL, typical Isuzu 5MT. I was going to buy my GF's until she smashed it up. I bet I'd still have it if that hadn't happened, the car I mean.

Damian,

You got that a little confused. The Asuna (built by Isuzu for GM) received the 140hp 1.8l and the Impulse came in two variations 1.6l N/A (Impulse XS) and 1.6l Turbo (Impulse RS). The Asuna was meant to fall between the two Impulses in terms of performance. The Impulse RS was around $6k more than the base XS and as a result, did not sell well.

I also screwed up above in the wheel/tire combo, the XS had 185/60/R15's and the RS/Asuna had 205/50/R16's for wheel/tire combo.

Keiho, YES the struts were THAT expensive.

Default Hmmm...

Thought they were the same car. Got the engine combos mixed up. It was a long time ago. I was pretty sure about the wheels though. The turbo I drove had 195/50/R15's & the lesser model had 185/60/R14's like on the Stylus. I didn't realize they ever came w/ 16's. Huh? You learn something new everyday. Wasn't my car anyway, Daddy bought her the car. I didn't mind in the least being the one to drive it. I remember it as handling better than any stock RS I've driven, but w/o the torque of our preferred brand. But that's just me, bad memory & all.

Keiho, A front quarter panel that someone scraped cost $1G just for the panel. Yes, they were expensive buggers to repair.
