1999 Chrysler 300M

The LH platform served as the basis for the Chrysler Concorde, Chrysler LHS, Chrysler 300M, Dodge Intrepid, Eagle Vision, and the final Chrysler New Yorker. A Plymouth to be called the "Accolade" was planned, but never saw production. The platform pioneered Chrysler's "cab-forward" design; featured on some Chrysler, Dodge, and Eagle cars in the 1990s and early 2000s.

Development[edit]

The LH platform was based on the American Motors-developed and Renault-derived Eagle Premier. According to Bob Lutz, "[t]he Premier had an excellent chassis and drove so dammed well that it served as a benchmark for the LH ... the spiritual father, the genetic antecedent of the LH is the Premier."[1] Like the Premier, the LH-cars featured a longitudinally-mounted engine with a front-wheel drive drivetrain, unusual in most American front-wheel drive cars, but a hallmark of Renault's designs.[2]

The, LH platform team was headed by François Castaing, who was previously responsible for product engineering and development at American Motors Corporation (AMC). Working with an engineering team of only 700, it took just over three years from the styling studio to the showrooms.[3] To give focus for the platform engineering team, the benchmark target was the Eagle Premier.[4]

As the 1990s dawned, Chrysler faced a renewed round of financial troubles. The US economy slipped into a recession following the 1987 Black Friday stock market crash and the Savings and Loan Crisis, but the company's main problems were due to a lack of engineering innovation and careless spending during the years of prosperity in the 80s. Most of Chrysler's lineup was based on the proven, but dated K-car platform, plus debt accumulated from expensive purchases including Italian automakers Lamborghini and Maserati, along with American Motors, and critics routinely criticized their inability to produce cars that were competitive with Japanese companies or Ford, which had just struck a coup-des-gras with the Taurus line.

It was also widely believed that Chairman Lee Iacocca had stayed at the helm of Chrysler too long. Thus, it was time for the automaker to make a fresh start for the 1990s. In 1992, Iacocca (who had just turned 68) was finally persuaded to retire. Although some suspected that he would turn the reigns over to Bob Lutz, he instead designated the more conservative, straitlaced Bob Eaton as new chairman.[5] This was because Chrysler faced an uncertain future and that its engineers were allowed to do what they felt was innovative. The LH vehicles were, generally, a great success for Chrysler and the cab-forward look influenced other car designs in the 1990s. Although the real "gold mine" of Chrysler's acquisition of AMC was the Jeep brand, their minivans and LH sedans also helped to bail the company out of almost certain bankruptcy in the 1990s.[6]

Chrysler advertised the advantages of the LH's "cab-forward" architecture (short, sloping hood and long windshield), and even used the platform name for the Chrysler LHS sedan. This look dictated one major design decision: the LH uses a longitudinal engine rather than the transverse engine position, which is more typical for front-wheel drive cars. This arrangement meant that the design team had to use a chain to connect the automatic transmission with the front differential, a design reminiscent of the original Oldsmobile Toronado. The transverse engine position generally uses a chain to connect the engine with the transmission, a higher-velocity application subject to greater wear and noise.

The Dodge and Eagle LH cars competed directly against the Ford Taurus and other mid-size cars, largely replacing the K-based C-bodies, The Chrysler models competed with upmarket domestics such as Buick and Oldsmobile. The LH cars debuted in 1993, and were updated in 1998. The LH platform was replaced with the rear-wheel drive Chrysler LX platform for the 2005 model year.

First generation (1993-1997)[edit]

The first generation LH cars used the existing 3.3 L OHV V6 as well as a new 3.5 L SOHC V6, and a four-speed automatic transmission.

Cars that used the first revision of the LH platform include:

All versions shared a 113-inch (2,900 mm) wheelbase. One year after the original three cars were introduced, the "stretched" LHS and New Yorker had different rear bodywork providing 5 inches (130 mm) more overall length as well as a revised rear seat providing more leg room.

Originally, Chrysler came close to giving Plymouth a variant of the LH platform, called the Plymouth Accolade, a name consistent with the then-current Plymouth Acclaim. It was to be a base model below the equipment level of the Intrepid. The Accolade never made it into production.[7]

Second generation (1998-2004)[edit]

The second generation LH cars used the 2.7 L DOHC V6 and 3.2 L SOHC V6, as well as an updated version of the older 3.5, and a four-speed automatic transmission.

Cars that used the second revision of the LH platform include:

When Chrysler discontinued the Eagle brand after 1998, the Chrysler 300M was introduced as a replacement for the Vision. All models again shared a wheelbase of 113 inches (2,870 mm). The 300M was several inches shorter than Concorde, Intrepid, & LHS, due to shorter front and rear overhangs in order to bring the car's length under 5 meters.

Media[edit]

One episode of Robert Reich's 1992 PBS miniseries Made In America focused on the then-yet-to-be-released LH's development and its role in reversing Chrysler's flagging fortunes. A camouflaged Dodge Intrepid is seen being put through the paces at Chrysler's test track, along with concept sketches and other behind-the-scenes activities.
