For
decades, GM developed different platforms for USA and Europe to suit
different
customer taste. American customers used to require bigger size and
lower
price, in contrast to European’s preference on smaller, sportier and
higher
quality cars. But since the Japanese invaded the market, the boundary
became
less obvious. American started appreciating quality, refinement and
driving
dynamics. That’s why they put Toyota Camry and Honda Accord on the top
of their domestic sales chart.
The last generation Chevrolet Malibu was not at all a traditional American car. It was born under the domination of Accord and Camry thus it already replicated some goodness of Japanese cars. However, it always trailed its rivals a little in all aspects bar reliability and affordability. GM came to a critical situation: if it want to match the Japanese, it will have to invest substantially into an all-new platform. But it could also be risky that the investment may not be returned. That triggered the decision to integrate its global development program. 3 global platforms were planned - Delta, the smallest platform, would give birth to Opel Astra, Fiat’s replacement to Stilo, Saturn Ion and Chevrolet Cavalier; Sigma, the largest platform, would power Cadillac CTS, Seville, a Buick, Holden Commodore and probably a luxurious Opel; Epsilon, the medium car platform, would be developed into Opel Vectra, Saab 9-3, Chevrolet Malibu and Pontiac Grand Am. After decades of isolation, GM is finally reuniting its cars across the Atlantic. If you have read my report for Opel Vectra, you will get this feeling: Epsilon is a sophisticated and highly rigid platform. Like that in the Vectra, the Malibu chassis employs high percentage (65%) of high-strength steel and a strong structure to enhance both safety and NVH. It also employs more sophisticated metals than ordinary Japanese cars, such as magnesium for the dashboard mount and aluminum for some suspension arms. The former reduces vibration through steering wheel while the latter reduces unsprung weight hence shocks transmitted into the cabin. Besides, the Epsilon platform rides on multi-link rear suspensions on a NVH-isolating sub-frame, far advancer than the old car’s MacPherson strut. Tailor to American taste, the suspensions setup of Malibu is a little bit softer than its European cousins. But that is only relative. Compare with Camry and Accord, you can easily feel it handles and rides more like European cars than Japanese or American cars. The ride is firm but soak up bumps well. Suspension noise is muted. The chassis feels solid, with no squeaks and rattles. Body control beats Japanese cars, with too little body roll, pitch and dive to talk about. However, don’t confuse it with the best handling family cars around - Ford Mondeo, Mazda 6 and European Honda Accord. These cars handles better than even Vectra itself, thus the softer-setting Chevrolet Malibu has no hope to match them. Besides, the electric power steering is too light at low speed and doesn’t give you much communication. But remember, what the Chevy competes with in the USA are just Camry and American Accord. It beats them in driver appeal, at least partially..... because its engines are relatively weak. The cheaper engine is the familiar 145hp 2.2-litre 16V Ecotec four-cylinder, smooth and economical but not powerful enough to please American. It is expected to take just 40% sales of Malibu. The remaining 60% is left to a 200hp 3.5-litre V6. This is an upgraded version of the previous 170hp 3.4-litre, thus it is still a 2-valve push-rod design. It produces decent bottom-end torque and is quieter and smoother than most push-rod engines, but it still trails the Japanese V6s in terms of eagerness and ultimate refinement. Moreover, its cast iron cylinder block makes the nose heavy and deteriorates the aforementioned fine handling. Perhaps the new platform is too expensive, Malibu has to cut cost in some other fields. The old-tech V6 is one example. The braking system is another. Not only ABS is not fitted as standard, but drum brakes are used at the rear. You had better to pay for upgrade. The interior of Malibu is just average. Higher quality than the old one but not up to the standard of Camry and Accord. You should also note that it offers slightly less space than its rivals because the integration with European platform actually makes the Malibu smaller than the last generation. For example, wheelbase is shortened from 2718mm to 2700mm, the same as Vectra. In theory, GM could have stretch its wheelbase by up to 150mm, but it reserves that for the Maxx version. Anyway, occupants are not short on comfort, because the cabin is well insulated from noise and vibration. That said, the
new Malibu
still need more effort to beat Camry and Accord. You may be tired of
this
conclusion, but I still have to say again: while it is not yet
successful,
GM is heading towards the right direction. |
