    Death rates fall as vehicles improve

    Drivers of late-model vehicles are a third less likely to die in crashes than they were a few years ago, but the gap between the best and worst vehicles remains wide.

    Hybrids have lower injury odds than nonhybrids

    The odds of being injured in a crash are 25 percent lower for people in hybrids than people traveling in the nonhybrid versions of the same vehicles, a new HLDI study indicates.

    Compatibility among vehicle types improves

    SUVs and pickups aren't the danger they once were to car occupants in two-vehicle crashes, a new IIHS study shows. Thanks to a voluntary agreement by the industry, the front ends of SUVs and pickups line up better with those of cars.

    SUV death rates fall

    Drivers in all types of vehicles are less likely to be killed in crashes than in the past. The change has been especially dramatic for SUVs.

    New crash tests: Small cars improve

    Small, fuel-efficient cars have made big strides on safety. Six of 13 small cars recently tested by IIHS earn Top Safety Pick awards, and none got a poor rating in any of four tests. The new tests include some of the most fuel-efficient vehicles available in the U.S.

    Low-speed vehicles don't belong on roads

    More and more, low-speed vehicles and minitrucks are being allowed on public roads next to larger, faster-moving vehicles. New crash tests show why this is a terrible idea.

    IIHS backs fuel economy plan

    IIHS supports government efforts to increase fuel efficiency through a vehicle attribute-based system that takes safety into account.

    Crash tests show how vehicle size, weight affect safety

    Three crash tests, each involving a microcar or minicar into a midsize model from the same manufacturer, show how extra vehicle size and weight enhance occupant protection in collisions. The physics of crashes dictates that very small cars generally can't protect people in crashes as well as bigger, heavier models.

    Physics dictates crash outcomes

    Principles related to force and distance explain the results of crashes between minicars and midsize cars.

    Fuel economy, safety aren't at odds

    Smaller vehicles use less fuel but don't protect as well in crashes. Fortunately, there are ways to improve fuel economy without compromising safety.

    Automakers improve crash compatibility

    Fifteen automakers have agreed on the first set of steps to reduce the risks to people in cars struck by larger and heavier SUVs and pickups.

    Saving fuel without sacrificing safety

    As Congress prepares to raise fuel economy standards, it should be sure to preserve the safety gains of recent years.

  • April 19, 2007 | Status Report, Volume 42, Number 4 | Special Issue: driver death rates

    Death rates vary widely by model

    Some passenger vehicles have much higher driver death rates than others. The average rate for 2004 and equivalent models was 79 per million registered vehicle years.

    Improving fuel economy safely

    Reducing vehicle weight but not size could improve fuel economy without sacrificing safety, a new study claims.

  • April 22, 2006 | Status Report, Volume 41, Number 4

    New fuel economy standards serve safety

    New federal rules will remove the incentive for auto manufacturers to meet fuel economy targets primarily by downsizing their vehicles, which is detrimental to safety.

    New fuel economy plan would help safety

    A proposed fuel efficiency standard for SUVs, vans, and pickup trucks would remove the incentive to increase sales of small, light vehicles to counterbalance gas guzzlers.

    Compatibility efforts reduce death risk

    Automakers' voluntary steps to reduce the mismatch between cars and SUVs are reducing fatality risk in the real world.

    Do SUVs put people in cars at risk?

    Crash incompatibility between SUVs and cars is a concern, but it's one that automakers and the federal government are working to address.

  • March 19, 2005 | Status Report, Volume 40, Number 3 | Special Issue: driver death rates

    Driver death rates vary widely by model

    The average driver death rate for 1999-2002 models was 87 per million registered vehicle years. Small cars and small and midsize SUVs tended to have the highest death rates.

    Voluntary compatibility standards

    Fifteen automakers have committed to voluntary standards that will boost head protection in front-to-side crashes and help reduce underride and override in front-to-front crashes.

    Improve fuel economy safely

    Current fuel economy rules favor the smallest, least protective vehicles. Changes could encourage manufacturers to adopt fuel-saving technology instead of downsizing vehicles.

    How size relates to safety

    Smaller vehicles consume less fuel, but don't protect their occupants as well as heavier ones. Driver death rates fall as vehicle size increases, up to a point.

    Study examines effect of vehicle weight on death rate

    As bigger and heavier SUVs get ever more popular, is incompatibility between vehicles in crashes becoming a big safety problem on U.S. roads? A comprehensive new study addresses this issue. The study focuses on fatal crashes involving 1990-95 model cars, pickups, and SUVs.
