Have today’s cars gotten safer or are automakers simply getting
better at designing cars that do well in crash tests? That’s long been
both a question and a concern among analysts and consumers, as each year
brings a larger assortment of models to market that ace tests conduced
by both the federal government’s National Highway Traffic Safety
Administration (NHTSA) and the insurance industry-supported Insurance
Institute for Highway Safety (IIHS).
Both organizations have raised the proverbial bar of late with more
stringent testing programs that have left automakers playing catch up.
NHTSA updated its safety-rating program for the 2011 model year with
tougher frontal- and side-impact evaluations, while the IIHS added a
“small overlap” frontal crash test to its regimen in 2012 that
replicates what happens when a vehicle’s left-front corner strikes a
pole or other obstruction.
For its part the IIHS acknowledges, even doles out accolades, to
automakers that design their vehicles specifically to do well in their
crash tests. In a press release announcing its latest round of results,
the Institute cited Honda for re-engineering its CR-V compact crossover
SUV and Toyota for modifying the Prius v hybrid-powered wagon in
response to poor showings in the small overlap assessment. Both received
top marks for 2015.
While it’s easy to become cynical in this regard, it’s difficult to
argue with success. Improved new-vehicle crash protection – combined
with added federal safety regulations and stricter seatbelt, drunk
driving and teen licensing laws at the state level – have combined to
drive traffic fatalities to historic lows that reached just 1.10 deaths
per 100 million vehicle miles driven in 2013.
Still, that amounts to 32,719 people killed in traffic crashes last
year, which means the industry still has a long way to go in order to
produce a truly “safe” car.
The latest frontier in auto safety is to help prevent vehicles from
getting into collisions in the first place. The federal government has
long mandated all cars and light duty trucks be fitted with antilock
brakes and stability control to help drivers maintain control of their
vehicles in panic stops and extreme handling maneuvers. Even better, a
growing number of models are offering systems that warn of potential
hazards, including when a vehicle is inadvertently drifting beyond
highway lane markers or signaling the presence of other vehicles in a
motorist’s blind spot.
The best are forward-collision mitigation systems that not only
engage audible and visual warnings if sensors determine the car is
closing in on the vehicle or other obstruction in its path too quickly,
but will tighten seatbelt, pre-prime the brakes at full stopping power
and will even engage the brakes at full force to help avoid, or at least
minimize the effects of a crash if the driver isn’t reacting quickly
enough. Most are designed to engage at higher speeds, though a few such
systems, most notably offered in Volvo models, work to prevent rear-end
collisions in stop-and-go traffic.
To that end, the IIHS recently updated its “Top Safety Pick+”
designations to recognize models that not only earn top (“good”) ratings
across the board in its frontal, side-impact, roof-crush, and
head-protection crash tests – including the aforementioned small overlap
test – but are able to successfully avert a collision or substantially
reduce a vehicle’s speed in tests conducted at 12 and 25 mph. Vehicles
that earn the top “superior” collision avoidance rating are able to
successfully avoid a crash or substantially reduce a vehicle’s speed in
both tests. To garner an “advanced” rating, a vehicle must include an
auto-braking function and be able to avoid a crash or reduce speeds by
at least 5 mph in either of the two tests.
