Surprisingly Unsafe, then Surprisingly Safe: the Chevy Lumina
The 1995 redesign of the Chevy Lumina has gotten its fair share of criticism. And yes, while it was rather homely looking and still mechanically heavily based on the 1990-1994 model, it brought a much-needed dose of safety to the model.
Let’s look at the 1990-1994 Lumina first. At that time, the NHTSA 35-mph full-frontal crash test was the only test conducted on new models for consumer comparison purposes. The Lumina’s risk of severe injury to the driver was 43%, placing it near the bottom of its class, and only earning it a low-end 2-star rating out of 5. This ranking is by worse occupant (e.g. if the driver had a risk of 20% and the passenger 10%, it would be ranked as 20%)
Ford Taurus: 15% / 11%
Honda Accord: 19% / 8%
Buick Regal: 22% / 7%
Mazda 626: 22% / 17%
Plymouth Acclaim: 23% / 10%
Toyota Camry: 21% / 23%
Mitsubishi Galant: 25% / 21%
Subaru Legacy: 28% / 14%
Buick Century: 18% / 31%
Nissan Stanza: 39% / 14%
Hyundai Sonata: 40% / 26%
VW Passat: 43% / 14%
Chevy Lumina: 43% / unknown
Chrysler LeBaron: 7% / 91%
(Tests conducted on various 1987-1991 model years, but all apply to 1990)
Out of 14 midsize sedans, the Lumina was second-worst – although the Nissan Stanza, Hyundai Sonata, and VW Passat were very close behind. Due to a data failure, passenger results were not available for the 1990 Lumina in the 35-mph test. NHTSA’s initial FMVSS 208 test for the Lumina showed a HIC of 1,084 and 45 chest G’s; that 1,084 HIC failed the maximum requirement of 1,000, and although Chevy did fix the passenger restraint system so it (narrowly) passed a re-test, the initial version is what was tested. Since the passenger did worse than the driver in the 30-mph FMVSS test, it is likely that the passenger’s performance would be worse than the driver’s in the more severe 35-mph test as well, although the risk would still likely fall below 91%.
Things changed dramatically with the 1995 Lumina, however. Thanks to airbags, the average midsize sedan was far safer in 1995 than in 1990 – but this time around, the Lumina jumped to the head of the class. NHTSA gave it 5 stars for the driver and 4 for the passenger, with injury risks of 9% and 13%, respectively. Looking at the 1995 versions of the aforementioned cars (some of which are successor models, or badge-engineered versions), we get:
Chevy Lumina: 9% / 13%
Subaru Legacy: 12% / 15%
Mazda 626: 17% / 10%
Buick Century: 14% / 17%
Mitsubishi Galant: unknown / 16% (unknown is likely 4-star, 11-20%)
Ford Taurus: 19% / 10%
VW Passat: 19% / 18%
Pontiac Grand Prix: 15% / 22%
Toyota Camry: 15% / 22%
Honda Accord: 18% / 24%
Nissan Altima: 13% / 24%
Hyundai Sonata: 25% / 20%
Dodge Stratus: 30% / unknown
There was major improvement between the 1990 and 1995 fleet, due primarily to the rollout of airbags; none of the vehicles scored less than 3 stars out of 5 for either occupant. Nevertheless, the Lumina jumped from second-worst in its class to the best, earning the lowest risk of driver injury of any of its competitors and still a close third-best out of 13 on passenger protection.
In addition, when the IIHS conducted its inaugural round of frontal offset crash testing in 1995 midsize and compact cars, the Lumina was one of only three to earn the highest rating of Good – alongside the Ford Taurus and more expensive Volvo 850 – and of those three, it was the only one to get all Good sub-ratings (the Taurus dummy’s head hit the side pillar, causing a risk of minor head injury, while the Volvo’s structure, surprisingly, collapsed a little too much; the Taurus got an Acceptable head injury sub-rating while the Volvo got an Acceptable structural sub-rating). With the Volvo’s NHTSA test injury risks at 10% for the driver and 20% for the passenger, that means that this Lumina beat Volvo in both types of frontal crash test. And the Volvo’s design was less than two years older.
When NHTSA started doing side impact tests in 1997, the second-generation Lumina’s perfect safety record did get a blemish – it earned 4 stars for front occupants and 3 for rear occupants, still quite a respectable score for 1997.
The Lumina was replaced by the Impala in 2000; it also would earn great crash test scores and just generally be a solidly-built and crashworthy car. And I’ve covered the Lumina’s predecessor, the Celebrity, on this blog; it was also very safe for its time.
Expect to see more older GM vehicles under both categories, surprisingly safe and surprisingly unsafe.
