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
Hybrids have a safety edge over their conventional twins, new HLDI research shows. The lower injury odds are in large part due to their bigger weight.

Vehicle compatibility improves
Recent changes to SUVs and cars have made crashes involving the two vehicle types less dangerous. Even pickups aren't nearly the danger to people in cars that they were before.

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.

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.

Mini-vs.-midsize tests show size is key
A series of tests in which a microcar or minicar was crashed into a midsize vehicle shows the important role that size and weight play in vehicle safety.
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.

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.

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
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.
January 3, 2004
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.
