Whether its carbon fiber, aluminum, or high-strength steel, automakers are putting more lightweight materials into their cars. That’s a good thing, because reducing weight improves everything about a car, from fuel economy, to acceleration, to handling. Weight reduction is also necessary to meet stricter emissions standards and compensate for the bloat brought on by a growing array of tech features. Lotus founder Colin Chapman’s maxim — “simplify, then add lightness” — still holds true.
One of these is not like the others. Active exhaust valves may not be the first things that come to mind when talking about cool car tech, but they’re techie nonetheless, and definitely cool.
When a button is pressed inside the cabin, cars equipped with this function open (or close) special butterfly valves inside the exhaust, unleashing or quelling the full sonic fury of the powerplant on the other side. This is especially helpful on loud cars like the Jaguar F-Type R, which can easily set off car alarms with its throaty V8 soundtrack. Simply hit the switch and the car quiets down to civilian levels … at least until the next straightaway.
Commuting is no fun. But advanced driver assist systems like adaptive cruise control can take a lot of the stress out of the experience. By using an array of sensors built into the car, adaptive cruise control can match the speed of the car in front of you, meaning you don’t need to constantly hit the gas and brake in highway traffic.
Some systems even allow the car to be brought to a complete halt and then resume automatically, making stop-and-go traffic considerably less frustrating. It might make you uneasy handing over some amount of control to the car, but we promise: use it once, and you’ll never want to go back.
It’s no exaggeration to say that the smartphone has changed everything, including how we interact with our cars. Most carmakers offer some sort of connected smartphone app, but some are better than others. Look for one that lets you remotely lock and unlock the doors, check the status of things like fuel and tire pressure, and even remotely start the car to warm things up on a cold winter’s morning.
Make sure to ask if there is a monthly or yearly subscription fee for the service, as it can vary from carmaker to carmaker.
Automatic Emergency Braking or AEB uses a variety of sensors to determine if a forward collision crash is imminent and automatically applies the brakes to diminish the severity or avoid a crash entirely.
The auto industry agreed to make AEB standard in cars by 2022, but many vehicles have it available today. The systems are extremely good, though you absolutely shouldn’t rely on it to stop you — it’s meant as a last resort for when the driver isn’t paying attention, and it’s extremely alarming when the system does engage. While Apple CarPlay and smartphone apps are important, this one could save your life, so it’s worth making this one a high priority on your shopping list.
