If you own a car and are among the 99 percent of Americans not driving an electric vehicle, you likely spend a considerable amount of time and money at the fuel pump. And, unless you plan to purchase an electric car, this continued fuel consumption is not going to stop — even Toyota Prius owners need to fill up occasionally.

However, there are some easy things to do, as well as habits to change, that will at least make your trips to the gas station less frequent. So not only will you be using less of the planet's finite gas reserves, you'll be spending less cash, too.

Proper inflation

Make sure your car's tires are inflated to the proper pressure. Don't use the maximum-pressure number on the tire sidewall, look for the sticker or plaque on the driver's side door jamb – these will show you the correct inflation numbers for your vehicle.

According to the U.S. Department of Energy (DOE), under-inflated tires can lower gas mileage by 0.3 percent for every 1 PSI that a tire is below its optimal pressure. In addition to the fuel savings, properly inflated tires are safer and will increase tread life.

Junk in the trunk

If you're hiking with a heavy backpack, you're going to run out of energy a lot sooner than if you're carrying a light daypack. The same reasoning applies to your car. If you're carrying around a 50-pound bag of dog food, the pile of books you keep forgetting to return to the library or your pristine collection of every print edition of the Weekly World News (BatBoy Lives!), your car has to work a lot harder, and therefore uses fuel more rapidly.

According to the DOE, every 100 pounds can drop fuel economy by one percent. So clean out the trunk, removing anything you don't need in there (best to keep the spare tire and jack, though), and you may find that your car actually has better performance as well as improved fuel economy.

​Lead foot or light foot?

Are you one of those people who sees every red light as a signal that a race is about to begin? The light turns green and you put your foot to the floor to beat the car next to you off the line. Although pretending you're a racecar driver can be fun, as those revs ramp up your gas gauge is quickly going the other way. Instead, be light and smooth on the accelerator and you will quickly see positive results in fuel mileage. There's also a lot less wear and tear on your car and tires when you take it easy on the throttle.

No speeding

A typical speedometer will indicate that the vehicle can go 120 mph —or more — and most modern cars are fully capable of going well beyond most posted speed limits. Not only will that practice get you an expensive speeding ticket or worse (a big repair bill, an extensive hospital stay, or a lavish lawsuit), it will also make your car guzzle gas like it's going out of style.

As your speed increases over 50 mph, your fuel economy rapidly decreases. This is especially true with many of today's smaller, fuel-efficient engines — with less power they have to work much harder as speed increases. Stick to the posted speed and you'll make it a lot farther before you need to stop for a fill-up.

Check your rack

Most modern cars go through considerable wind-tunnel testing to make them as aerodynamic as possible, which improves efficiency and performance. When you put a large rack or cargo box on the roof, all of that wind-tunnel work gets blown away. The DOE estimates that a roof-mounted cargo box can decrease fuel economy as much as 25 percent at highway speeds. Skis, boats, bikes or other equipment carried topside have similar results. Granted, there are times when you legitimately need to carry these items, but remove them when they're not needed. Whenever possible use a rear-mounted carrier, or pack your gear inside.

Windows down or air conditioning?

Everyone wants to be comfortable in their car, and when it gets too hot, the answer is to either roll down the windows (in most cars, of course, "roll down" means push the button) or turn on the air-conditioning. At slower speed when driving around town, lowering the windows makes the most sense.

Air-conditioning puts a load on the engine and will definitely reduce fuel economy. However, at highway speeds lowered windows add considerable drag on your car, which in turn reduces fuel economy. So if you're going to be on the freeway, raise the windows and turn on the AC — there will still be a drop in fuel economy, but this is the lesser of the two options.

Or, you can go with option three (AC off, windows up), but we really don't recommend that during the dog days of summer.

Plan your itinerary

If you have a number of places to go, make a plan to cover them all in one outing. Shorter trips with a number of cold starts will use much more fuel than if the engine only has one cold start and stays warm for the rest of your drive. It's also beneficial to plan your route to reach all your destinations with the shortest driving time. Be sure you choose the right time to go, if you can — avoiding rush hour will reduce your stop-and-go driving, improving both your fuel economy and your mood.

Avoid idling for a long while

Sitting in your car with the engine running is quite inefficient — that's obvious. When you're not moving, you're getting zero miles per gallon. According to the DOE, you can use a quarter to a half gallon of gasoline per hour while idling — possibly more depending on engine size and if your air-conditioner is running. This is why many newer cars shut themselves off automatically when you brake to a stop, restarting automatically when you release the brake. If you're going to be waiting in your car for a while, shut it off. It doesn't take much fuel to restart it, and you'll be saving gas and money, as well as being good to the environment.

Cruise control

Keeping a steady speed on the highway can go a long way to improving fuel economy, and using cruise control is the easiest way to do that. However, this method only works when the road is relatively flat —cruise control will try to keep a vehicle's speed constant even when climbing hills or mountain roads, which makes the engine work harder, thus burning more fuel.

Proper motor oil

Most people don't specify a type of oil when getting their oil changed, but this too can affect your fuel mileage. Look in the owner's manual to see what grade of motor oil your vehicle's manufacturer recommends for your car — using the correct oil can improve fuel economy up to two percent.

Buy a new, more fuel-efficient car

Clearly this isn't an option for everyone, but cars today are among the most fuel-efficient ever produced, so if you are in the market for something new this is your chance to make a difference. If you can increase your fuel economy from 15 mpg to 30 mpg, based on $3 per gallon and 15,000 miles of driving per year, that's a $1,500 savings each year — enough coin for quite a few lattes. Added bonus: odds are the new car will be running much cleaner than your current ride.

Be hybrid and electric vehicle savvy

Even if you have already made the jump into a very efficient vehicle, there are still ways to improve your mileage. Avoiding hard braking will make better use of the regenerative braking system, putting more energy back into the batteries — for free. Any vehicle that you can plug in should be plugged in whenever you have the chance — especially true for plug-in hybrids, since the more charge you have, the less often the internal combustion engine will need to run. Most of these vehicles have indicators to tell drivers how to drive more efficiently. Listen to your car — it knows what it's doing.

Public transportation

Okay, okay, so we're being Captain Obvious. And Americans love their cars, so this may be the most difficult fuel-saving tip to follow: Leave your car at home. Take a bus, ride your bike, carpool to work (with this option you still get to drive, sometimes) or if the distance is short enough (or you're in really good shape) you can simply walk. It may be a no-brainer, but the less you use your car, the less fuel it will use.

The AWD ID.4 model is on its way.

Volkswagen

There was a lot of buzz when VW introduced its 2021 ID.4 all-electric crossover with rear-wheel drive earlier this year, but there's plenty more now that the Wolfsburg automaker has added an all-wheel-drive version. The 2021 VW ID.4 AWD gets another motor onboard this compact SUV that brings all-wheel-drive traction. The SUV appeals to buyers in the snow belt states but will also tickle the fancy of performance enthusiasts. Now with motors on both the front and rear axle, there is nearly fifty percent more power, with impressive gains to horsepower and torque as well as the added battery-electric boost to that scoots the 5-seater from 0-60 mph in 5.7 seconds (the RWD model took 7.5 seconds to achieve the same).

2021 VW ID.4 AWD An extra motor brings AWD to the ID.4.Volkswagen

On sale now, the 2021 VW ID.4 AWD Pro starts at $44,870, before federal or other incentives; this is a $3,680 premium over the rear-drive model. The AWD Pro S starts at $49,370; both models are eligible for $7,500 income-tax credits. It's worth noting that current delivery estimates for the AWD Pro are running into 2022. The AWD Pro trim has been rated by the EPA at 249 miles (only 11 miles less than the Pro RWD) while the AWD Pro S has been validated at 240 miles (as compared to 250 miles). The AWD Pro has been rated at 102 MPGe for city driving/90 highway/97 combined; the Pro S gets 93/98/88. Both are rated at 2,700 towing. Competitors include the Ford Mustang Mach-E and Tesla Model Y.

While the AWD and RWD look the same outside, one exterior badge designates the newest variant with an "AWD" badge, plus it gets 0.6 inches of added ground clearance, slightly bigger brakes and sway bars. From the front, the electric SUV has smoothed jelly-bean styling that is highlighted by standard LED headlights and standard black roof rails that sit atop the body-colored roof. From the rear, it wears hatchback-like looks.

2021 VW ID.4 AWD The ID.4's cabin is tidy and upscale, no matter the model.Volkswagen

We drove both the Pro and Pro S versions, with different premium interior trims and found the Gradient Package ($1500) visually upscale and appealing. It brings a black roof with silver rails, along with 20-inch wheels and the availability of King's Red Metallic paint, as a $395 option. The Pro is well-equipped with attractive trim elements and an impressive collection of communication and infotainment technologies. Pro S comes with a glass roof with an electrically-retractable shade and front seats with leatherette upholstery and 12-way power adjustments (including four-way lumbar support and a massage system).

We drove the new ID.4 AWD over a course of 160 miles along a variety of roads to sample its handling and ergonomics. The interior has a clean and open feel with good visibility. Controls and gauges are well-placed and the seatbelts are height-adjustable, while a configurable console holds different drink sizes and has removable cupholders. A futuristic LED "Light" strip with 10 different ambient lighting selections extends across the dashboard and pulses with directional signals, incoming phone calls, navigation prompts and other in-cabin inputs (optional is 30-color lighting selection on the Pro S). Driving is also a bit futuristic with no stop/start button; the vehicle senses the approaching key and can start climate control, unfold side mirrors, unlock doors and illuminate door handles at night, among a number of other high-tech features. There is 30.3 cubic feet of stowage behind the rear seats and up to 64.2 cubic feet with the second row folded. Under the floor storage holds the charging cable and small items. Pro S has an adjustable trunk floor that can be raised and lowered and a ski passthrough.

Pushing the brake pedal triggers the ID.4 to begin motoring, with the option of a "D" mode for typical driving or "B" for a more regenerative driving experience. Travel Assist brings semi-autonomous driving. Notable is the fun and responsive torque-on-tap, well-balanced direct steering and a suspension system that allows the small compact to maneuver well through traffic and along twisty roadways, as well as an impressive turning radius. The vehicle dynamics control system is integrated with the stability control system and an electronic differential to seamlessly engage the front axle, when needed. Volkswagen has added a different asynchronous motor to the front with a permanent-magnetic synchronous motor at the back for a combined 295 hp. and 339 lb.-ft. of torque.

2021 VW ID.4 AWD The ID.4 AWD will start shipping in early 2022.Volkswagen

Carried over are 82-kWh battery packs and the 5 to 80 percent fast-charging time of 38 minutes, when using 125kW fast-charging. VW says it can add 62 miles of range in 10 minutes; home charging on a Level 2 charger is projected to take approximately 7.5 hours for a full charge.

Of note: VW includes three years of complimentary charging up to 125 kW, with any ID.4 purchase or lease; VW Group's Electrify America charging network has over 650 stations and more than 2,700 fast chargers.

New compact luxury SUV

2022 Lexus NX gets new tech and PHEV drivetrain

The NX is all-new for 2022.

Lexus

The NX may not be Lexus' most popular SUV – that title goes to the RX – but it's got a lot to offer in a compact package. Lexus redesigned the NX for 2022, and the big stories are its new PHEV powertrain, updated tech, and improved safety features.

The 2022 NX 450h+ is Lexus' first plug-in hybrid vehicle. It's expected to deliver 36 miles all-electric range, 84 MPGe combined, a 0-60 mph time of six seconds. It's joined in the NX lineup by the NX 350h hybrid, which uses a 2.5-liter four-cylinder engine with two high-torque motor-generators that produce a combined output of 239 horsepower. The NX 350h is capable of returning 39 mpg combined and a 0-60 mph time of 7.2 seconds.
