Neo-Classic Car: 1993 Oldsmobile Achieva SCX

By Chris Haak


When I tell most people that I used to own a 1993 Oldsmobile Achieva SCX, I typically get one of two reactions.  Either they have never heard of the car before, or they have heard of the car and think that I immediately lose all credibility as a gearhead for having owned a car as lousy as the Achieva.

On the lack of name recognition, I’ll attribute that to a combination of GM’s propensity to rename the next generation of a model rather than just, you know, improving it (the Cutlass Calais begat the Achieva, which begat the Alero, which was the last Oldsmobile ever produced), and the fact that on the whole, the Achieva was a forgettable car with a stupid name.  My explanation to this group is usually something like, “it was the Oldsmobile version of the Pontiac Grand Am, but with a nicer interior and a Groucho Marx face.”

For the people who have heard of Achievas, they picture the geriatric four-door models with a 120-horsepower “Quad OHC” four cylinder coupled to a three-speed (or four-speed if you’re lucky) automatic, plastic wheel covers, and a foolishly ugly rear wheel opening shape.  My explanation to these folks is usually, “not that kind of Achieva – mine was a two-door, five-speed, 185-horsepower homologation of a showroom stock race car.”

Indeed, the SCX was an interesting car that GM in its current state would never build, even if Oldsmobile still existed.  The Achieva SCX was produced only during the 1992 and 1993 model years, and in a hat-tip to the days when each GM division built its own engines, the SCX had a special version of the Oldsmobile-developed Quad 4 called the W41 that had a different cam profile, higher (7,000 RPM) redline, and lower restriction exhaust that produced an additional 10 horsepower over the “regular” high output Quad 4.  Today, there is no such thing as a “Buick engine” (though the recently-departed 3800 V6 certainly is a Buick engine) or a “Chevy engine” (though the 60 degree V6 in the Impala and a few other cars, plus the Small Block V8 trace their roots back to the Chevrolet division of GM).  The 2.3-liter W41 Quad 4, which had a red IDI (integrated direct ignition) cover that said, “W41 – Manufactured exclusively for Oldsmobile by General Motors” instead of the normal black anodized aluminum version of the regular H.O., produced 190 horsepower in the 1992 SCX and 185 horsepower in my 1993 SCX.

Oldsmobile had used the W41 engine in a special version of the previous-generation Cutlass Calais Quad 442 sold in 1990 and 1991 (I’m sure that fans of the original Olds 4-4-2s wanted to pull their hair out upon seeing a front wheel drive 1990 Cutlass Calais with their beloved name on the side, based on the way the GTO faithful reacted to a tamely-styled, yet still V8 rear wheel drive reincarnation of that famous nameplate a decade later).  When the Calais bowed out in favor of the Achieva for the 1992 model year, the Achieva SCX took the mantle of the highest-performance Oldsmobile N-body car (actually, it was the highest performance Oldsmobile period in the 1990s).

Some of the exclusive features that set the Achieva SCX apart from the more pedestrian Achieva SC as well as its corporate cousins that shared the same platform were:

  • quarter inch silver pinstripe at the top of the body cladding
  • body color rocker panels (on the Achieva SC, they were painted flat black)
  • electronic suspension adjustment (soft/sport/auto)
  • +10 horsepower over the regular high output Quad 4
  • 5th gear was not an overdrive gear
  • no upshift light
  • rear track was 34 mm wider
  • upgraded clutch
  • 14 inch five spoke wheels instead of the 16 inch wheels on the regular Achieva SC
  • V-rated BF Goodrich tires P215/60VR14 tires (while the regular Achieva SC had P205/55R16 tires, because the 14 inchers were 215s and the 16 inchers were 205s, the car actually handled better with the smaller, wider tires)
  • Cars without air conditioning (of course, mine did have air conditioning) also had a few other performance features to facilitate racing:

  • baffles in the fuel tank
  • external oil cooler
  • I acquired my red 1993 SCX – which I’d later learn was one of about only 500 1993 SCXs produced – in early 1994 with less than 5,000 miles on the clock, and was the car’s second owner.  I owned the car throughout most of my college years, and upon landing my first job, kept the car for about a year until deciding that a noisy, red compact car was not “professional” enough, and upgrading to a 1998 Bravada SUV.

    Performance of the SCX was excellent for its day; zero to sixty times were generally in the high 7’s, and quarter mile times were generally in the 15s.  The wider rear track and grippy BF Goodrich tires really helped handling, and the steering wheel had a thick rim and nice organic shape.  While the brakes weren’t upgraded from the standard Achieva, meaning that it had front discs and rear drums (larger brakes probably wouldn’t have fit inside those puny wheels anyway!), ABS was standard and braking performance was far better than that of GM cars made in the previous few years.  The gearshift was connected to the Getrag-sourced five-speed manual by cables, and the linkage was very notchy and certainly not up to contemporary expectations.  On cold days, it was even worse.  Reverse gear was not synchronized, meaning that you had to come to a complete stop and either put the car into a forward gear first, or wait a few seconds before engaging reverse.

    The low-restriction exhaust and a Quad 4 made for a very noisy combination.  I wish I had a nickel for every time someone asked me if I had a problem with my exhaust system, but in fact, it kept the same high noise level from the first day I drove the car.  When I was sneaking home late at night after stretching my curfew a little far, I had to cruise down the block past my parents’ house, do a U-turn, then shut off the engine and coast to a stop in front of the house to not tip them off that I was coming back so late.  While the exhaust was noisy, it didn’t have the artificial unmuffled note that a Civic with a coffee can muffler does today.  Being a four cylinder, true dual exhaust was of course not possible, so a single pipe came from the exhaust manifold to a muffler on the left-rear of the car, then a pipe exited the front of that muffler, moved across the rear of the car under the trunk, and into a resonator that was half the length of the real muffler.  This made it possible to have two tailpipes that actually emitted exhaust.

    The Achieva had, in my opinion, a nicer interior than did its contemporary platform-mates, the Pontiac Grand Am and Buick Skylark.  Where the Pontiac had shiny hard plastic on its dash, the Achieva had shiny soft plastic.  As you can see from the photo to the right, the gauges were huge and very legible.  Climate and audio controls fell right to hand, and the car had a fairly large glovebox.  The seats were unfortunately quite flat, but since I was in my late teens/early 20s when I owned the car, they never bothered me.  My SCX had a six-speaker stereo with a single-disc CD player that could really kick out some nice sound.  I’m sure I would complain about that stereo today, but I loved it in 1994.  My biggest complaint about the interior was that the car had no airbags, but instead used door-mounted passive restraints.  The theory was that you could just leave the belt buckled at all times, then slide under them when entering the car.  In practice, I just used them as regular seatbelts, but in an accident, there were cases where the door would fly open, and suddenly the occupants aren’t belted to anything.  Later Achieva models had a redesigned dash with dual airbags, and reverted to the more conventional B-pillar mounted belts.  The only positive of the door-mounted belts was that it made rear seat entry pretty easy.

    The W41, aside from being noisy and course, was pretty darn quick.  The engine pulled strongly all the way to its 7,000 RPM redline, and seemed to have a flat powerband.  It’s telling that even today, 15 years later, the 2.4 liter Honda Accord does not match the W41’s power output from its 2.3 liters (yet the Accord does so at half the volume and harshness!)  You could hit 60 mph just as second gear was running out of revs.  Aside from the NVH problems that Quad 4 engines had, another reason GM no longer puts them into cars is that nearly every single one has had a head gasket failure.  Some people like me get lucky and get a slow leak that is fairly easily remedied, while others experience catastrophic failure, with antifreeze going everywhere and a lot of smoke billowing from under the hood.  Mine failed around 50,000 miles and was replaced for free under a “secret” GM warranty, in spite of the car being out of its 3 year/36,000 mile factory warranty.

    A particularly unique feature I haven’t spoken much about yet was the electronically adjustable suspension.  While I was never able to find details on how this worked (in spite of my best friend’s persistence in asking), it had three pushbuttons on the far left side of the dash marked “Auto,” “Sport,” and “Soft.”  Under the hood, there was no sign of it except for a few small wires going into the strut towers.  I kept it on Auto 99% of the time, but it was definitely possible to feel a difference when the suspension was set to Sport; in that setting, every small bump on the road made its way to the passenger compartment.  I’m guessing that of the surviving Achieva SCXs, very few still have a working electrical suspension.

    Of course, I’ve both owned and driven many cars that were more reliable, more powerful, more comfortable, better looking, and more refined than my old Achieva SCX was, but I still have a special place in my heart for that car.  Why is it that a guy who owns a 300 horsepower sport sedan still craves a noisy four cylinder compact car?  I have no idea, but if I had the garage space, time, and money lying around, I’d be all over any opportunity to own another one.  Unfortunately, I have none of the three, so the SCX just has to live in my memories.

    1. As the proud former owner of a 1971 Cutlass Supreem (with the gold painted “Rocket 350” engine), I can say we all died a little bit inside when Olds built a FWD Cutlass.

    2. We built the Achieva in Lansing, back in the days when we built almost half a million cars a year around here (I worked on the Grand Am/Skylark/Cavalier line for a while in the mid-90s). I sort of liked the styling–better than its more popular sister the Grand Am–and the interior was pretty decent by contemporary GM standards, which were admittedly rather lacking.

      I wish GM had continued to build the high-output Quad Four; it was always a noisy, troublesome engine, but you might as well get some extra horses with the drama. My step-brother still has an Achieva, but I think it has the more reliable V6.

      It’s strange how certain early automotive experiences have a lasting effect. My two favorite cars are probably the 1976 Buick Electra 225 I had in high school and my first new car, a 1993 four-door Cavalier, special ordered with AC, rear defrost, passenger side mirror and no other options. I have driven much nicer and better cars than both–quite frankly, almost any car was “better” than that Buick–but until I got my 1962 Mini, nothing has quite worked its way into my heart the way those cars did.

    3. there was some attempts around the mid-1980s then Pontiac attempted to revive the GTO by using the Grand Am, I spotted these old magazine scans at

    4. I forgot to mentionned, imagine the havoc it would created if there was a Grand Am GTO-Quad4…

    5. It’s a bit plain, innit it? Reminds me of some of the styling-challenged cars in Britain in the late Seventies.

    6. I loved the sound of the W41 quad four. Someone at my university had one when I was in school and the sound always made my head turn. It was very distinctive. You are very correct that the sound is much different than the lawmower-type sound of putting a big exhaust on a modern civic. Good memories.

    7. WOW.

      The things you find on the internet.

    8. Yeah I had a 92 scx and I loved it. Still do I guess I can’t tell you how many Rice burners I smoked with that 190 hp sleeper. No one expected the performance it dished out.

    9. Looked just like that top pic too candy apple red and everything.

    10. I had a 93 SCX and loved it, I had planned on keeping it forever and then the front end was damaged by a deer. Being that it wasnt original anymore I lost interest in it. I owned that car when I was young and really ran it into the ground. Blew up the transmision and they were all gone at the time(bought by the people who raced them) and the dealership that worked on it had to order in each piece individually it cost just over 4800.00 to repair it and it never was the same. I can honestly say that it held up pretty well, like I said earlier I was young and ran it pretty hard!

    11. I put a honda engine in place of my quad 4

    12. My first car was a 1992 Achieva SCX. Like John, I was young and ran it hard. I went through the first set of tires and brakes pretty quickly. It handled spectacularly with the suspension in Sport mode (and that’s where I left it most of the time) and scared/impressed quite a few passengers. Loved the look of the engine and the sound of the exhaust. Didn’t have any engine or transmission problems with mine despite 145,000+ miles and 11 years. I regret parting with it but at the time, I just didn’t have the money to keep it around and restore it. Now I’m looking to get my hands on another one, restore it, and take it out to the track for some laps on occasion.

    13. I’ve been lucky enough to own a 92 and a 93, both brand new. Rolled the 92 while on vacation in MO (long story). Car held up like it had a roll cage. Very impressed. Got home and 93 was in stock, and dealership cut me an offer I couldn’t refuse.

      Still have the 93, though I don’t drive it as much as I used to. Got 194K on the clock and still pulling 30mpg hwy. Sure, it’s got its quirks but I can overlook a lot for what it can still do…which is scream like a banshee on the highways, and not just the sound. Sometimes you just feel the need for speed. 🙂

    14. k i have a question if my car is makin a tingin sound like crap is bouncing around my catalac converter should i just straight pipe it i dont car if its not legal i just want it to sound good….97 acheiva 3.1 liter v6 fart can?

    15. The special Auto/Soft/Sport suspension worked by changing the size of the orifice that fluid in the shock absorber would flow through as the shock absorber was compressed. The retail cost from Oldsmobile for one of the front absorbers was around $1100 in 1995.

    16. I didn’t have the SCX W41 but did want one badly. My Achieva did have a 5-speed which made for an exciting ride. I loved how the driver side reminded me of a cockpit with all the controls in such easy reach. I think that is what actually drew me to purchase the car. Even though it wasn’t a powerhouse it was still a very memorable car…

    17. I just pulled my Black 1993 SCX out of storage the other day and it is so much fun to drive compared to my SOHC Accord station wagon. Sure the accord sits more comfortably and rides nicer for cruising but but the powerband in the Olds is so much better, worlds of difference.

      As for the RWD 442’s and the FWD ones, I’m a fan of both. My dad had a few old RWD 442’s. Then I bought a 1990 Calais 442 and that thing was very impressive and fast. 0-60 @ 7.0 and 1/4 mile in the 14’s, I would venture to say this was faster than a lot of the older cutlass cars, not a W30 for sure, but certainly it earned a respect of it’s own!

    18. Nobody will probably read this but here goes…
      My brother bought a very low mile 1992 SCX and drove it around while in college. After he graduated, it was no longer cool enough for him so he wanted to trade it in on a new 1997 Mustang GT. I was looking for a second car and asked him what the trade-in value was. For $3k I got a clean, always babied, 92 SCX and had no idea that it was a wolf in sheeps clothing. The first time I wound out 1st and 2nd gears I was hooked. It was no longer fun beating up on Honda civics with my 400+ hp LT1 Trans-am and in those days riced out imports were all the rage. Being the tweaker that I am the SCX became the recipient of some minor mods like a performance chip, custom air intake, msd box, and a custom 2 1/2 exhaust with extrude-honed exhaust manifold. Talk about deceptively fast, I could walk away from my brother’s mustang from any speed and it ran low 14’s all day. Not the sexiest-looking car ever made, but what a fun car to drive and got surprising gas milage as well. I sure miss that nasty little w41 quad engine’s idle, WOT sound, and awesome powerband.

    19. I loved it when I showed up at a local 1/4 mile dirt track in a 1990 Calais automatic quad4 and passed them all… so next year it was.. can’t beat em.. join em… now there are more than a few at racing at the same track…

    20. Reading others memories of the scx brought back fond memories of my 2nd car (I didnt realize what I was getting, my parents told me I could only get a 4 cylinder “because there not fast”.

      I had the 92 achieva SCX and love(d) that car. It was unsuspectingly fast, and handled great for what it was. I too experienced the dreaded head gasket failure which resulted in a rebuild packed full of go fast goodies. Bigger cams, worked over W41 head, msd ignition, custom tune, custom intake and custom exhaust (2 1/2″ into dual 5″ tips) good for 235 to the wheels.

      I didnt know what to expect from the exhaust sound when I took the car to the shop to have the exhaust made and installed, I recall the owner chuckling when I told him what I wanted – he didnt try to talk me out of it, just asked for payment. Little did either of us know that the car would sound like a hopped up big block. If anyone lives in Plano TX, you would most definitely remember the car from its sound. You could hear me coming from half a mile away.

      After that the car was virtually uncatchable on the street. Growing up in the DFW area street racing was an every weekend thing for me. I wouldn’t back down from any challenge but due to the sound of the car it was very common for mustang GT’s and Z28’s owners to walk away. I beat my share of opponents and it was great doing it in the odd looking american made little 4 banger.

      I drove the car cross country 4 times with no issues at all, got 30+mpg on the highway and over 25 mpg in the city. I regretfully sold it when I joined the Marine Corps because I had to many cars. I sold it to a friend who drove it to 275k (with 3 more head gasket rebuilds) before it just gave up.

      I have sinced owned several camaro’s, few corvettes, an Audi A5, BMW M3, currently a CTS-V wagon. All very respectable cars yet none of them can bring the excitement that my little over achieva did. I am currently keeping my eyes open for another one of these to rebuild.
