Is Safety Compromised by size? Huge cost of mismatched bumpers

When bumpers on cars and SUVs don't line up (and many of them don't), low-speed collisions produce more damage and higher repair costs

ARLINGTON, VA - Bumpers are the first line of defense against costly damage in everyday low-speed crashes. Bumpers on cars are designed to match up with each other in collisions, but a long-standing gap in federal regulations exempts SUVs from the same rules. New Insurance Institute for Highway Safety crash tests demonstrate the results: SUV bumpers that don't line up with those on cars can lead to huge repair bills in what should be minor collisions in stop-and-go traffic.

"SUVs and cars share the road," says Joe Nolan, the Institute's chief administrative officer. "The problem is they don't share the same bumper rules, and consumers end up paying the price."

A federal standard requires that all cars have bumpers that protect within a zone of 16 to 20 inches from the ground. This means car bumpers line up reasonably well and are more likely to engage during low-speed collisions to absorb energy and prevent damage. No bumper requirements apply to SUVs, pickups, or minivans, so when these vehicles have bumpers they often are flimsier and higher off the ground than bumpers on cars. Plus, SUVs and pickups may not have bumpers at all.

In fender-benders with SUVs, cars often end up with excessive damage to hoods, engine cooling systems, fenders, bumper covers, and safety equipment like lights. SUVs don't always come out unscathed either, often needing extensive work.

The Institute conducted 10 mph front-into-rear crash tests involving 7 pairs of 2010-11 models, each composed of a small car and small SUV from the same automaker.

"We picked vehicles from the same manufacturer because we think automakers should at the least pay attention to bumper compatibility across their own fleets," Nolan explains. "The results show that many don't."

In the tests, an SUV going 10 mph struck the back of its paired car, which was stopped. Then the configuration was reversed, with the car striking the back of its paired SUV. Results of these low-speed impacts varied widely, from a total of $850 damage to one vehicle to $6,015 damage to another. In some cases, the crash damage included major leaks from broken radiators and cooling fans. If these collisions had happened in the real world, the motorists wouldn't have been able to drive away. If they did, their vehicles could overheat, and the engines could be ruined.

Mismatched pairs: If bumpers don't match up, they'll bypass each other when vehicles collide, and the resulting crash energy will crumple the vehicle body. That's what happened when the Nissan Rogue struck the back of the Nissan Sentra in the SUV-into-car test. The Rogue's front bumper didn't line up at all with the Sentra's rear bumper, and the resulting $4,560 rear damage tally for the Sentra was the highest among all the cars in this test. The impact crumpled the car's bumper cover, trunk lid, and rear body. The Rogue ended up with a crushed and leaking radiator that kept the SUV from being driven after the test.

Bumper height mismatch contributed to pricey damage when the Ford Escape struck the rear of the Ford Focus. Their bumpers overlapped less than 2 inches, not enough to protect the Focus's rear body and trunk lid from $3,386 in repairs.

"The mismatch problem with the Ford pair was even worse when the Focus struck the back of the Escape. The front bumper on the car underrode the high-riding Escape's rear bumper, which at 25 inches off the ground is the tallest among all the small SUVs evaluated this time around. Damage to the Focus came to $5,203 and included replacing most of the sheet metal plus many parts in front of the engine.

When the Toyota Corolla hit the rear of the Toyota RAV4 in the car-into-SUV test, damage amounted to nearly $10,000 for the pair - the highest combined test damage among all of the vehicle pairs the Institute evaluated. The RAV4 accounted for about $6,000 of the bill.

"The RAV4's so-called bumper is really just a stamped piece of sheet metal supporting the bumper cover," Nolan explains. "So instead of engaging a strong bumper, the striking Corolla hit the spare tire mounted on the RAV4's tailgate. The spare isn't designed to absorb crash energy, so it damaged the Corolla's hood, grille, headlights, air conditioner, and radiator support and crushed the RAV4's tailgate and rear body panels."

Compatible bumpers: Bumpers on Honda's CR-V and Civic were the most compatible in the test in which an SUV strikes the rear of a car, and at $2,995 the pair had the lowest combined estimated damage in this crash test. The Civic's $1,274 damage was the lowest among the cars. The CR-V is one of only 3 SUVs whose front bumpers overlapped half of the rear bumpers on the cars they hit.

"The CR-V's front bumper overlapped the Civic's rear bumper by more than 2 inches. That may not sound like much, but it's enough to allow the bumpers to do what they're supposed to do," Nolan says.

When the Kia Forte struck the back of the Hyundai Tucson, their bumpers matched up well enough to keep the Forte from underriding the SUV, limiting damage to a combined $3,601 for both vehicles. The Forte's $1,510 repair estimate was the lowest among cars in the car-into-SUV test.

The Tucson-Forte pair's bumpers also did a good job of lining up in the SUV-into-car test. The Tucson's $850 damage estimate was better than the other SUVs, and it was the only SUV that didn't have a damaged air-conditioning condenser.

Despite bumpers that aligned, results for the Forte weren't as good. The Forte had more than $3,000 rear damage because its bumper broke during impact. The car's rear body panel also was damaged.

"Of the 7 car-SUV pairs we tested, we can't point to a single one as a model of compatibility because combined damage estimates run into thousands of dollars for even the best performers," Nolan says. "In the real world that money comes straight out of consumers' wallets through deductibles and insurance premiums. Regulating SUV bumpers would ease the burden."

Regulate SUV bumpers: The Institute in July 2008 petitioned the National Highway Traffic Safety Administration to regulate bumpers on SUVs and pickups the same as cars, and require them to match up in a way that shields both vehicles from costly damage. The agency in June 2009 agreed to seek comments on the petition but hasn't moved forward with a rulemaking or a low-speed compliance test for bumpers.

Regulators have long said that requiring light trucks to have bumpers would compromise off-road maneuverability and make it hard to use these kinds of vehicles at loading ramps. The Institute counters that very few SUVs and pickups are used off road. In addition, bumpers aren't the limiting factor in most vehicles' approach and departure angles. Instead air dams, bumper covers, exhaust pipes, and other trim mounted lower than the bumpers get in the way

Kicherer SLS 63 Supersport released with art photography

Instead of sending us the usual press shots, Kicherer has spiced things up by tapping renowned photographer Frank Luger to give his vision of the new SLS 63 Supersport.

While we're partially distracted by the model, the Supersport features a carbon fiber front spoiler, a stainless steel exhaust system, a new rear diffuser, and forged RS-1 wheels. To ensure the pricey components aren't ripped off when you enter a parking garage, the car has been outfitted with a lift-up system that raises the vehicle 30mm (1.2 inches) at a touch of a button.

Lastely, Kicherer has also optimized the 6.3-liter (6208cc) V8 engine to produce 610 PS (455 kW / 602 hp) and 670 Nm (494 lb-ft) of torque. While the company declined to explain the modifications, they contribute an additional 39 PS (29 kW / 38 hp) and 20 Nm (15 lb-ft) of torque.

Honda going to offer a new, 2011 "value-oriented base model at $18,200

Honda announced today that it is going to offer a new, 2011 "value-oriented base model" of the Honda Insight hybrid starting at $18,200, plus destination charge of $750. That's $1,600 less than the current lowest-priced 2010 Insight, the LX.

The new value base Insight model, which goes on sale today, is rated with the same mileage as the other Insight models: 40 miles per gallon in city and 43 mpg on the highway.

When the Honda Insight was introduced in early 2009, it was intended to compete as a more affordable alternative to Toyota Prius. But the final sales price of the Insight, typically in the low $20,000s, is not that much cheaper than a Prius—and the fuel economy is considerably lower. As a result, the Prius outsells the Insight by a ration of about 5 to 1. Nonetheless, in recent months, the Insight has become the second best selling hybrid in the United States behind the Prius—beating out the larger more expensive Ford Fusion Hybrid.

In April, Takanobu Ito, Honda’s president, said he was not satisfied with Honda’s hybrid technology, and charged engineers with producing the next Honda hybrids with fuel economy that beats the Prius’s combined 50-mpg rating. At the 2010 Los Angeles Auto Show earlier this month, Honda unveiled a new two-motor full hybrid system capable of achieving that goal. Coming at the heels of the L.A., the announcement of the lower priced Insight base model indicates Honda’s seriousness about hybrids—and its diligent efforts to simultaneously lower the cost of its hybrid models while significantly increasing fuel efficiency.

Honda said that all three 2011 Insight models will offer vehicle stability systems as standard equipment. The new base Insight comes standard with anti-lock braking, automatic climate control, power windows and remote entry, Honda's continuously variable transmission, a tilt and telescoping steering column, 60/40 fold-down rear seats, Honda's Eco Assist driving behavior feedback system, 2-speaker audio system with CD player and an auxiliary audio input and front, front-side and side-curtain airbags.

The LX trim level, which will be priced at $19,900, adds cruise control, a four-speaker audio system, an armrest console, floor mats and a security system. And the top-level EX, which starts at $22,240, includes alloy wheels, steering-wheel paddle shifters, six-speaker audio system and heated side mirrors with integrated turn signals.
