New Saab 9-3 to rival Audi A3 - AutoCar.co.UK

21 June 2010
Saab will declare its independence as a carmaker with the launch of an all-new 9-3 in late 2012. Rebadged as the 93, the new model will also mark the reintroduction of a hatchback version reminiscent of the classic 900.

Saab is working on a new platform — known internally as the ‘Phoenix Architecture’ — that will underpin the next-generation 9-3 family as well as the eventual replacement for the latest 9-5, which has just been launched.

It’s expected that the first car based on the Phoenix Architecture will be the new 93 saloon, which is currently pencilled in for a 2012 launch.

Getting this new car into the showrooms is a priority for a company that badly needs to boost its sales and dramatically increase its cashflow.

A cabriolet and a three-door hatchback will follow hard on the saloon’s heels. The drop-top and hatch are closely related, being nearly identical to each other up to the doors and frameless window arrangement.

The 93 Sport Wagon will be the final model in the range, sharing the majority of its construction with the saloon...

Re: Saab 93 - first rendering & news - PART 2

Next Saab 9-3's tech revealed - also AutoCar
21 June 2010
The Phoenix Architecture that will underpin the 93 is aptly named; indeed, it is so crucial to Saab’s recovery that the firm’s engineering guru, Kjell ac Bergström, has put his retirement on hold for two years to oversee the project into production...

The essentials of the Phoenix Architecture

Front suspension

For the Phoenix architecture, Saab has a choice of existing suspension systems. It could use the standard-issue MacPherson strut fitted to base versions of the 9-5.

However, MacPherson struts have limitations. They allow more vibration and disturbances from the road through to the driver and are prone to allowing torque steer with powerful engines.

Their construction means that they are also more susceptible to distorting under hard cornering, which leads to much less precise steering response. Many within Saab are now arguing that the Phoenix platform should actually be fitted with the much more sophisticated HiPer Strut.

HiPer Strut

The name is derived from High Performance Strut. This front suspension set-up was designed by Saab engineers for General Motors’ Global Epsilon project.

According to the company, the advanced HiPer Strut offers driving benefits similar to those of a double wishbone layout. “The inclination, length and offset of the kingpin is reduced and the castor angle of the steering increased.

“The result: improved steering quality with a more ‘planted’ feel, as well as enhanced handling and braking characteristics.”

Rear Suspension

Base 9-5s use a four-link independent axle, designed by GM and also used on the Insignia. It’s regarded as a capable design, but Saab also has the option of the much more sophisticated linked H-arm set-up.

Linked H-Arm axle

The linked H-arm was also developed by Saab technicians and is available on both front-drive and all-wheel-drive cars. The company says because it has isolated subframe mountings (unlike the four-link axle), it gives even greater ride comfort, reduces vibration entering the cabin and improves roadholding.

All-wheel drive system

Saab’s XWD (Cross Wheel Drive) system is based around the familiar and quick-acting Haldex 4 clutch, which is mounted on the rear differential. Torque can be transferred front to rear depending on grip levels (using 20 sensors checking information 100 times a second).

The trick aspect is the limited-slip differential on the back axle. Dubbed the eLSD, it can distribute torque between the wheels, meaning the torque can be variably split between all four wheels, matching levels of available grip.

New engines for the 9-3

By assembling its own platform, Saab is free to buy in engines and transmissions from virtually any supplier. One Saab source told Autocar that using an existing GM platform (such as the Astra’s Delta underpinnings) meant that it would probably have to adopt matching GM engines and transmissions.

The new Phoenix Architecture might be built around the new BMW/Mini engines, but it’s likely that Saab will design its own DSG transmission because BMW uses conventional auto ’boxes.

So, it will still be based on an Old GM platform. This company is not long for this world.
maybe it's cuz my little econobox that thinks it's a sportscar is almost eleven years old
but
I really think basic Platform science hasn't developed any new 'killer apps' lately...

...now sub-systems like revo-knuckle & control-blades (which imho CAN be stuck on older platforms) are a 'nother thing - - imho

OR
maybe it's cuz Saab is in the running to be my new redheaded-stepchild icon???
SAAB
gimme an "S"...
