Thought you'd like to know that the next Saturn small car, replacing the S-Series, will be renamed ION. According to GM/Saturn, the name is "ION" (all capital letters and it's not an acronym) just like the new SUV is "VUE".
The ION will be offered in coupe and sedan forms and should be marginally larger than the car it replaces. Power will come from a version of the L850 engine used in the VUE and L-Series, probably around 2.0L. A CVT may be offered.
The ION will be introduced late in 2002.

The ION got announced yesterday, but nowhere can I find any photo's. I can find photo's on the SKY, but not the car verified to be released. Anyone have a clue where to find photos of the ION?

All-New Saturn ION Sedan and Quad Coupe Designed to Re-Energize Small-Car Segment
Blending innovative thinking, segment-leading features and unprecedented personalization opportunities, the 2003 Saturn ION sedan and quad coupe deliver excitement and value uniquely tuned to the needs of small-car buyers. The new series of ION cars will debut in the fourth quarter of 2002.
The two ION models are completely new from the ground up and offer surprising refinement for the small-car segment. Even the name is new, since they replace the pioneering S-Series in the Saturn lineup. Both the four-door sedan and the "quad coupe" - so-called because of its dual rear-access doors (RADs) - are built on the new General Motors Delta small-car architecture. The quad coupe's dual RADs represent an industry first, resulting in the creation of a new category of vehicle and a new, more functional small car.
"The ION sedan and quad coupe are going to re-energize the small-car arena," said Jill Lajdziak, vice president of Saturn sales, service and marketing. "These new models bring surprising levels of personalization and customer-friendly features to the segment, including a larger exterior, more interior room, a new powertrain, and enhanced ride and handling."
Attracting younger buyers
The new models also will play an important role in GM's entry-level strategy to attract more young buyers by providing a selection of vehicles with high value and fresh designs. One of the keys to attracting young buyers will be an emphasis on making it easy for customers to personalize their vehicles through "personal accents" kits. Planned exterior customization includes interchangeable roof rails that are color-coordinated with interior trim kits consisting of bezels for the center-mounted instrument panel, shifter and HVAC control panel. Saturn also plans to offer a full range of retailer-installed accessories when the IONs are introduced.
Another important plus for young buyers is that both the ION sedan and quad coupe will have significant safety content - a hallmark of the Saturn brand.
The ION small cars continue the ongoing revitalization of Saturn's product portfolio, which for 2003 also includes the VUE compact sport-utility vehicle and the refreshed L-Series mid-size sedan and wagon. The ION will be built along with the VUE in a partial split-line arrangement at Saturn's manufacturing facility in Spring Hill, Tenn.
Like all Saturns, the ION sedan and quad coupe will be sold and serviced through Saturn's award-winning network of retailers who are recognized leaders in satisfying customers. Saturn retailers have finished number one in the J. D. Power and Associates Sales Satisfaction Index for six of the last seven years.
Distinctive siblings
While siblings, the sedan and quad coupe use distinctive exterior styling cues, but leave little doubt that both are Saturn family members. The ION sedan brings a refined, sophisticated, contemporary look to its segment. Meanwhile, the quad coupe creates an entirely new product category by incorporating rear-access doors on both the driver and passenger side and an overall sporty flair. Both vehicles continue the Saturn tradition of polymer side panels, including the integral upswept "swoosh" body side styling.
Inside, a unique feature is the incorporation of a center-mounted instrument cluster. This innovative styling cue not only makes the sedan and quad coupe more distinctive, but also enhances the driving experience by helping keep the eyes closer to the horizon. In addition, positioning the instrument cluster in the center allows the driver to comfortably position the steering wheel, without having to position it to read instrument gauges.
The center-cluster design made it possible to give the ION a unique, small diameter steering wheel, part of an interior design that focuses on harmony and overall refinement. Other examples include tactile surfaces throughout, thin structural A-pillars, and a sloped center console to enhance the perception of airiness while improving ergonomics and visibility.
New architecture
Built on GM's all-new Delta architecture, the five-passenger sedan and four-passenger quad coupe continue Saturn's traditional spaceframe construction. The new architecture allows the ION models to be substantially bigger than their predecessors - approximately 2 inches taller and 6 inches longer - providing a more significant command of the road. In addition, a wider track (approximately 2 inches front and rear) and longer wheelbase delivers a more substantial presence.
The new, stiffer Delta architecture leads to significant improvements in noise and vibration, as do hydraulic engine mounts, dual balance shafts on the Ecotec™ powerplant, and enhanced noise dampening throughout the vehicle.
On the inside, the seating position is significantly higher for both front and rear occupants, improving entry and egress and providing a more commanding view of the road. The quad coupe is equipped with "fold-flat" passenger front and rear seats for enhanced functionality to the small-car market. Both models feature significant interior storage, including three bins in the instrument panel, CD storage in the console, and map pockets in both the front and rear doors. In addition, the ION sedan is expected to have the most trunk room in its class - and the quad coupe's dual RADs and fold-flat seats bring so much versatility that even items such as a stepladder, or even a small kayak, can be toted in its interior compartment.
Fun to drive
Both the ION sedan and quad coupe are equipped with an outstanding powerplant that delivers fun-to-drive performance when mated to any of three state-of-the-art transmissions.
The Ecotec 2.2-liter, GM's global four-cylinder engine, is standard in all vehicles. Currently offered in the Saturn VUE sport-utility vehicle and Saturn L-Series mid-size cars, the Ecotec becomes available for the first time in a Saturn small car with the ION models. The 137-horsepower, 16-valve, dual overhead cam (DOHC) powerplant incorporates dual balance shafts for quiet operation and provides excellent response in a wide range of driving situations.
A world-class, five-speed manual transmission is standard for all ION models. GM Powertrain's VTi automatic transmission - a continuously variable transmission (CVT) that provides an infinite number of gear ratios over a wide overall ratio range - is optional on base and mid-level models. This is the first application of a CVT on a high-volume compact passenger car in North America.
The VTi allows the engine to operate more efficiently than a traditional step-ratio automatic transmission. This enables the vehicle to achieve nearly the same fuel economy as a manual transmission, while still providing excellent launch performance along with smooth and responsive power delivery.
Up-level sedans and quad coupes are available with a five-speed automatic step-gear transmission - a feature typically reserved for premium vehicles. Compared to conventional automatics, the five-speed provides closer steps between ratios for acceleration when needed, particularly during passing.
The ION models are equipped with an electronic power steering (EPS) system - a first-time small-car application on a domestic GM vehicle. EPS contributes to gains in fuel efficiency by eliminating the power steering pump. The speed-sensitive system incorporates variable effort steering that is tuned to optimize customer feel and effort. Independent front and semi-independent torsion beam rear suspensions, along with front and rear stabilizer bars, a wider track, and a longer wheelbase add to the ION models' improved ride and handling over their S-series predecessors.
The ION models' turning circle also has been engineered to provide the maneuverability expected in the competitive small-car segment.
Advanced safety features
The ION sedan and quad coupe carry on the Saturn tradition of leadership in the areas of safety and security. The world-class structural design provides the foundation for a safe environment. The spaceframe's front and rear crush zones help absorb the energy of a crash while protecting the integrity of the safety cage.
Dual-stage driver and passenger air bags are standard, and Saturn's innovative head-curtain air bag system - which help reduce the risk of head and neck injuries for both front and rear occupants in certain side impact collisions - is optional. In addition, front seatbelt pretensioners, three-point safety belts for all seating positions, and new LATCH (Lower Anchorages and Tethers for Children) child-seat attachment system are all standard equipment.
OnStar®, with its array of safety, security and convenience features, is available as an option on both the ION sedan and quad coupe - a segment first that will take Saturn's reputation for safety and security to an even higher level.
Small-car market
The Saturn ION sedan and quad coupe will compete in a small-car market that accounts for sales of more than two million units per year, about 14 percent of the total U.S. new vehicle market. Approximately 30 percent of small-car purchasers are first-time new vehicle buyers.
The ION models continue Saturn's historic position of offering premium small cars - competing primarily with Asian imports - and targeting a more educated, informed target market with their safety and quality brand attributes. Like all Saturn products, the ION sedan and quad coupe were designed to appeal to customers who would have otherwise bought a non-GM product. More than 75 percent of Saturn buyers list a competitive make as their second-choice vehicle, with over half saying they would have bought an import brand.

the grey car in the pics, sort of reminds me of an audi for the curved roofline of the car and the new altima for the rear angle of the trunk, and well the front end still says SATURN at least the lights are spaced to the corners of the car unlike earlier models which sandwiched the lights in the center.
overall i think saturn is getting better.

I think I would have to drive the car to see if I like it. It seems to me that it makes you pull your eyes too far off the road (in therory). Plus when you have crabby ass grandma in the back seat that doesn't like to go over 55 mph, she now has full view, and can bitch at you the whole way!!!

Looks like a nice ride. The front looks like a Holden or Old's type design.
Saturn must be clearing the SL1's out to get ready for the ION - they are flying off the lots at sweet deals. I picked one up even though I hadnt thought of Saturns previously. The deal was just way too good on it. Turns out I actually like the car and am quite pleased with it except for the horrible skinny Firestones on it.

I took mine down to Discount Tire right after I bought it. They gave me a good trade in deal on those stupid Firestones. I got some 60 series Michelin's... what a difference.
Congrats on the new car!!

The engine in the ION is very similar to the 2.2L DOHC (different from the OHV 2.2L) engine found in other FWD cars from GM. It's in the Cavalier/Sunfire and Grand Am/Alero as well as the Saturn L-Series.

Yes it is. By the way, that is "echotech" not "econotech" ya ball buster. It is also tuned way down for the EPA and air people. Add a simple resistor to the air intake sensor and you will be up 8-10 hp without even bolting parts on. Cost $5.00. This engine has been co-devolped by GM and Lotus. Smooth, sound and a great paltform for power mods.

dang nabbit. its an ecotec not econotech not echotech!
its a 2.2L 140hp 142ftlbs
it was first in the L series saturn. now its in the vue, the ions and from now on into next year just about every gm 4cyl car out there. saabs have them, cavaliers/sunfires i believe already do... i forgot the others.
best 4cyl engine ever! (im my opinion of course)
i dont feel like lookin for it but if you guys wanna research what gmp (general motors performance) has done with an ecotec, please look it up. 1,000+ horsepower...maybe 6.9 but i know for sure 7.0/7.1 second quarter mile times in a drag cavalier with the 2.2...engine can handle 400 hp stock....block can handle 700hp.
and please, no one buy that intake resistor on ebay for $5...it does nothing and costs like 10 cents to make, try radioshack if you really want it.

Ah cripe, am I throw-en in too many constanants again.
Your damn straite its of the best. Have you stopped to look at the factory stock intake chambers that help to boost naturally aspired intake velocity.
Not bad for a US bred motor. (well, Lotus fed most of the design to GM so there.) Is Lotus GM too? :eek7:
I would be curious to see what the change in Torque/HP are with a standard wide-open intake. Seeing as how this engine has been tuned down for MPG and EPA, I would bet the supprise is a good one.
Hey bro, On the Resistor caper. What hardware mods did you combine it with?
I stumbled on the same Idea about 2 years ago and found that it does work with some minor limitations. If you correctly guage the resistance
to turn out the right amount of fuel, I found a considerable increase in both below 4k and above 4k rpm. With some essential bolt-ons of course. By itself or if too much resistance is applied, a loss of power may be experienced.(too much fuel) Not only does it adjust the pulse width but a minor advance in timing can be gained as well.
The big issue with Saturn PCM's is that they will always try to achieve
stoichiometric fuel ratios. (Lean and clean) At engine shut down, if the resistor is left in line with the intake temp sensor it becomes part of the closing reading.
The way I found to get arround that is to install a true bypass switch and turn the added resistance circuit off a few minutes before shut down. When you start the engine next time, do not turn the added resistance back on until the engine has finished with warm-up. This way it is always an incidental reading, not part of the cluster of constant averages.
Ehhhhhhh? :lol2:
As well because ambient conditions change constantly, I devised a block of resistance in 1/2 ohm increments so I could from the cock pit make the adjustment on the fly. Position 1 is bypass, from there we climb to 10 ohms 1/2 ohm at a time.
Or maybe I am just a bull shisster. try it, you tell me.
Keep yer footers mashed down till the gass is gone.
Peace :sunglasse

man i hate it when i write a reply and it doesnt go through!!!!!!!!!
haha
are you australian or canadian?
yes lotus has been a part of the design or gm borrowed from them or something...and something else really strange... the lotus elan has the same steering wheel as first gen sl/sw saturns, so obviously there is something between them and gm... they are also close with isuzu it seems
as for the intake ports, i have not seen them but i would be very interested in knowing what they look like and how they increase air velocity to the chambers. venturi effect or what kind of shape do they use? i would also definetly like to see a dyno on an ecotec with the intake/exhaust opened up.
as for the iat resistor thing...i have never tried it, and i had heard of people having problems with it under different conditions, the details i'm not sure of but i'm sure its what you're describing...im sure it was related with timing
i'm not very knowledable in the electrical field, your expertise has humbled me... so id wish you could explain how the iat works, what ohms it outputs or whatever and how different temperatures affect its output...i like what you're talking about there by changing the ohms from inside your car, but how do you know which ohms to leave it at, trial and error type deal? what do you mean by the resistor becomes part of the closed reading at shut down.
i would be very interested in the specifics
by the way i have found my car to run better with lowered fuel pressure, ive only done a few bolt ons and the such, nothing requiring much extra fuel like forced induction/nitrous/headwork/raising compression or something of that nature. funny though.
what have you done to your car? and what do you drive.
haha
are you australian or canadian?
yes lotus has been a part of the design or gm borrowed from them or something...and something else really strange... the lotus elan has the same steering wheel as first gen sl/sw saturns, so obviously there is something between them and gm... they are also close with isuzu it seems
