Poor headlights cause 40 cars to miss IIHS Top Safety Pick rating

Over the past few months, we've noticed a number of cars and SUVs that have come incredibly close to earning one of the IIHS's highest accolades, the Top Safety Pick rating. They have great crash test scores and solid automatic emergency braking and forward collision warning systems. What trips them up is headlights. That got us wondering, how many vehicles are there that are coming up short because they don't have headlights that meet the organization's criteria for an "Acceptable" or "Good" rating. This is a revision made after 2017, a year in which headlights weren't factored in for this specific award. This is also why why some vehicles, such as the Ford F-150, might have had the award last year, but have lost it for this year. We reached out to someone at IIHS to find out. He responded with the following car models. Depending on how you count, a whopping 40 models crash well enough to receive the rating, but don't get it because their headlights are either "Poor" or "Marginal." We say depending on how you count because the IIHS actual counts truck body styles differently, and the Infiniti Q70 is a special case. Apparently the version of the Q70 that has good headlights doesn't have adequate forward collision prevention technology. And the one that has good forward collision tech doesn't have good enough headlights. We've provided the entire list of vehicles below in alphabetical order. Interestingly, it seems the Volkswagen Group is having the most difficulty providing good headlights with its otherwise safe cars. It had the most models on the list at 9 split between Audi and Volkswagen. GM is next in line with 7 models. It is worth noting again that though these vehicles have subpar headlights and don't quite earn Top Safety Pick awards, that doesn't mean they're unsafe. They all score well enough in crash testing and forward collision prevention that they would get the coveted award if the lights were better.

2018 Buick Regal GS : The 310-hp American hot hatch

Buick has spent the last decade shredding its perception as the low-level luxury vehicle for geriatrics, but the brand hasn't always been associated with that crowd. In fact, ask some enthusiasts and you'll hear about the GM 3800 series engines, IndyCar racing, and the mythical GS and GNX. In that high-octane theme, GM pulled back the curtain on the all-new, all-wheel drive, 310-horsepower 2018 Buick Regal GS Wednesday morning in Milford, MI. The GS is basically a sport-tuned version of the all-new Buick Regal. We've seen the standard and high-riding wagon variants, but this is our first look at what's likely to be the enthusiast pick. The Regal GS uses the five-door sportback bodystyle from the standard car (though a GS version of the TourX would be awesome), swiped from GM's soon-to-be former German division, Opel. While a number of automakers are downsizing engines, Buick is soldiering on with its tried and true naturally aspirated 3.6-liter V6, in this guise making 310 horsepower and 282 lb-ft of torque. Power is sent to all four wheels through a nine-speed automatic. The all-wheel drive system uses a twin-clutch setup and has been tuned specifically for the GS. The Regal GS makes more power than both the Acura TLX A-Spec (290 horsepower) and the Lexus IS350 F-Sport (306 horsepower). The V6 features both cylinder deactivation and auto stop/start for better fuel economy. The fully independent suspension uses the second-gen Continuous Damping Control (CDC), capable of 500 adjustments per second. Selectable modes allow the driver to tailor the car to fit the situation. Large Brembo front brakes are surrounded by standard 19-inch wheels and tires. The exterior gets a few styling changes like a sporty front and rear fascias, a small rear spoiler, and plenty of GS badges. Inside, the Regal GS gets unique sport seats with integrated headrests and adjustable lumbar and thigh bolsters. They even come standard with heating, ventilation, and massaging functions. The driver faces a GS badged flat-bottom steering wheel and GS-specific pedals. A full-color heads-up display is optional. Available safety features include front pedestrian braking, lane keep assist with lane departure warnings, forward collision alert, automatic emergency braking, and adaptive cruise control. The real key for the success of the Regal GS could be pricing.

2018 Buick Enclave: How engineers made it larger, lighter, more sophisticated

Buick used the unveiling of the 2018 Enclave at the New York Auto Show to introduce its new range-topping Avenir sub-brand to the world. With fancier interior finishes and exterior details, it's Buick's latest effort to make itself a proper luxury brand (or perhaps re-establish itself as such). However, lost in the Avenir song and dance is the fact that the 2018 Buick Enclave is a (very) long-awaited all-new model regardless of the trim level one selects. Like the Chevrolet Traverse upon which it is based, the new Enclave is bigger than the vehicle it replaces but considerably lighter, by about 400 pounds. "We told every engineer, 'get your job done, but then take the weight out,'" said engineer Rick Spina as we hovered next to his larger yet lighter creation. His team therefore set about taking a little bit of weight out from just about everywhere, from using additional aluminum in the suspension to varying the thickness of the frame (thicker in places that needed to be stronger, thinner and therefore lighter in places that didn't). Only about 100 pounds came out of the body with the rest coming from elsewhere. Not only will the reduced weight improve fuel economy (Buick-estimated at 19 mpg combined with FWD versus 18 for the 2017 model) and presumably the old Enclave's rather ponderous handling, but it should only make things easier for the new powertrain: General Motors' now-familiar 3.6-liter V6 and its latest nine-speed automatic. With 302 horsepower and 260 pound-feet of torque, Buick says the new engine will need 7.2 seconds to reach 60 mph with FWD or 7.5 seconds with AWD. That's a second quicker than before. Besides acceleration, towing is also bumped up by 500 pounds to 5,000. For those models with all-wheel drive, the Enclave has the same basic system featured on range-topping versions of the Buick LaCrosse. Besides power being sent front and rear, it can also differ from right to left in the back, although Spina is quick to point out that capability is for traction-enhancing purposes rather than sporty, handling-enhancing torque-vectoring ones. Buick owners already appreciated the Enclave for its quietness so the engineers decided to take it that much further. This included altering the exhaust, improving body sealing (there are triple door seals), including active sound deadening and utilizing advanced materials that absorb sound as opposed to simply being thick, dense and heavy enough to keep it out.
