Rare Rides Icons: In Memoriam, The Chrysler LX Platform (Part III)


October 7th, 2022 12:25 PM

Thus far in our Chrysler LX platform coverage, we’ve discussed two designs that never made it past the working concept stage. The first of those was the Airflite, a Crossfire-styled hardtop hatchback, while the second was the larger Nassau which was also a hardtop hatchback. Neither of them had pillars, and both focused on the future of car design. 

Journalists made incorrect predictions at the debut of both concepts and stated that the Airflite (in 2003) previewed the upcoming 300’s styling, while the Nassau (in 2007) was a sneak peek at a new styling direction for the 2008-ish revamp of the then-current 300. While those assumptions were wrong, a never-debuted Nassau design from 2000 was the actual genesis of the 300’s styling. And it appeared on the new LX platform in 2005. 

The LX was derived from the deceased front-drive LH platform, which as we know was benchmarked to the AMC-generated and Renault-derived Eagle Premier. Chrysler aimed for product differentiation with its new platform, and some within the company knew that while its previous front-drive LH cars were successful, every mainstream manufacturer offered that sort of product as well. 

Chrysler found in its research that the consumer’s impression of a rear-drive car was almost always associated with a higher price. Product development realized it could make more profit on each car and get the differentiation it desired with a rear-drive platform. It was not as easy to convince Chrysler’s engineers of the move to rear-drive, as they preferred to make a new version of the front-drive LH. 

In the late Nineties Chrysler began such a development: a revised take on the LH to carry Chrysler through the middle and latter part of the 2000s. However, the company reached the end of its independence days at the time, as in 1998 it merged with Daimler-Benz AG and became Daimler-Chrysler AG. Shortly after the merger, management decided to call the LH a day and drop further development. 

For its part, the LH platform was designed so it could easily swap between front- and rear-drive. In the end, the persuasive product people (and Daimler with its execution of LH development) came to an understanding with the engineers on a rear-drive platform. Though it was in theory a merger of equals, the management at Daimler stated it was also important to save money and to use things Mercedes-Benz had already engineered. 

As mentioned above, what happened, in the end, was a derivative of the LH platform. LH was reworked to be rear-wheel drive and used a front suspension that Chrysler developed “itself” (see below) while its rear suspension was from a contemporary Mercedes E-Class (W210, 1995-2003). Mercedes also provided a 5G-Tronic five-speed automatic, which was a new feature of the E-Class in 1997.

However, there is not agreement between sources about just how much parts sharing there was between Mercedes and Chrysler on the LX. While Chrysler claims to have developed the front-end suspension itself, other sources suggest the double wishbone setup was derived from the S-Class (W220, 1999-2005). Further, it’s also suggested the lower control arms in the LX suspension were taken from AMG’s E55, and are interchangeable between the two cars. All-wheel drive examples of the 300 used the Mercedes 4MATIC system from the E-Class and its transfer case.

Other assertions of Mercedes parts usage include the driveshaft, differentials, the ABS system, cabin electrics, engine modules, and the steering. It doesn’t end there, as the 300 featured the cruise control stalk from the E-Class, as well as seat control buttons, HVAC internals, and its wiring harness. Again, information varies depending on who’s answering the questions.

Less up for discussion were the platform’s new dimensions. The translation of the LH platform into LX brought with it an increase in wheelbase. The 300M of 2004 used a 113-inch wheelbase, a full seven inches shorter than the 120-inch wheelbase of the subsequent 300. 

Despite the longer wheelbase and how the cars looked on the outside, the 300M and 300 were the exact same length: 197.8 inches. Width shrunk by .3 inches, from 74.4” to 74.1” with the move to the LX platform. The overall height of the new 300 was 58.4 inches, a jump of 2.4 inches from an LH 300M. Chrysler made the LX cars taller to give them a more distinctive shape.

Said distinctive shape was a referential one, as penned first by Tom Gale and then finalized by Ralph Gilles and Freeman Thomas. Thomas was new to Chrysler from Volkswagen and was appointed VP of Daimler-Chrysler’s Advanced Product Design Strategy. Gale retired before the Nassau concept made the move toward production as the 300. 

The new 300 was penned as a modern interpretation of the classic C-300 of 1955. The Imperial-adjacent 300 was also designed by Virgil Exner and shared similar looks to the independent and upscale Imperial. Rather than credit the unreleased Nassau design of 2000, Chrysler made a reference to the Chrysler Chronos of 1998 (above). We’ll leave it up to you to decide which is closer in looks to the production car. 

The 300’s bold styling was led by its large egg crate grille at a time when the oversized grille was just arriving to its modern usage. With Chrysler’s gold ribbon logo sporting large wings, the 300’s face appeared almost vertical. Large headlamps were rounded on the outside and sharp on the inside and recessed slightly from the grille. 

The sedan had a large one-piece front clip that included the bumper cover, lower valance, and grille. Upper trims (SRT8 shown) had large fog lamps astride some air inlets in the lower valance, and headlamp sprayers set into bumper-like trim underneath the headlamps.

Elsewhere, the 300 was strong, solid, and blocky looking. The large hood was almost flat save for a minor power bulge and curved down to meet the headlamps. Fenders also wrapped around the headlamps and then headed toward the rear. The 300’s character line was interrupted by very strong front wheel arches but was otherwise nearly horizontal.

The side profile of the 300 had a minimal amount of decoration, apart from its door rub strip and a trim name badge at the front fender. Upright and formal, the 300 also looked hunkered down and sporty. Chrysler succeeded in its reference to the Fifties “gentleman’s muscle car” that was the 300.

The rear end sported a high deck, and a simple and squared-off trunk lid. It had a strong character line at its lower quarter that was similar in effect to the side character line. The trunk also sported a large Chrysler logo and a trim designation badge on occasion. Below, there was a very simple bumper with minimal trim or decoration, just cut-outs for the exhausts and a place for the license plate. 

A handsome-looking car for the 2000s, and certainly more appealing than most (or all) of the rather mushy-looking second-generation LH cars. It also succeeded in looking different from most anything on the road at the time. Next time we’ll have a look at the interior accommodation of the 300, and talk about trim and mechanical details.
