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 newest member of the BMW family is also the quickest and most powerful production BMW car ever made. The limited edition 2022 BMW M5 CS Sedan will be made for just one model year.

The model builds on the BMW M5, which was recently updated for the 2021 model year and combines an amplification of power with a weight reduction to achieve its performance and dynamics that enhancing both on-the-road and track capabilities of the 5 Series.

The design of the M5 is mostly unchanged with the new car, however there are definite differences. There is extensive use of carbon fiber reinforced plastic. There is a gold finish on the BMW kidney grille, model badging, and 20-inch forged light alloy wheels. The adaptive LED headlights feature L-shaped light tubes that illuminate to yellow instead of the standard white. There is a BWM Individual Shadowline trim that adds a dark shaded appearance and accentuating the yellow accent lighting.

The M5 CS is available in a standard Brands Hatch grey metallic paint with two optional BMW Individual colors – Frozen Brands Hatch grey metallic and Frozen Deep Green metallic.

BMW's engineers have tuned the car's 4.4-liter twin-turbo V8 to achieve 627 horsepower, a 10-horsepower increase over the Competition model, and 553 pound-feet of torque, delivered in a wider band than the M5 Competition. The engine is paired with an eight-speed M Steptronic automatic transmission with Drivelogic. The M5 CS reaches 60 mph in just 2.9 seconds, 0.2 seconds quicker than the M5 Competition model. Top speed with the standard M Driver's Package is 190 mph.

The rear-biased M xDrive all-wheel drive system is standard on the car and is able to distribute all of the available torque between the front and rear axles. The Active M Differential further optimizes power between the rear wheels for maximum grip and lateral dynamics.

Drivers can select from three xDrive modes including 4WD, 4WD Sport and 2WD. The Dynamic Stability Control system can be adjusted to DSC ON, MDM (M Dynamic Mode), and DSC OFF. The Drivelogic switch on the gear selector lever allows three modes - Efficient, Sport, and Track.

There are three drive modes: Comfort, Sport, and Sport+. Individual configuration is available. Drivers can toggle between Road, Sport, and Track settings using the M Mode button. Engaging these modes also changes the look of the driver information screen and head-up display. Road mode is the default setting.

The M Driver's Package also includes a voucher for BMW driver training.

The car's dual-branch, electric flap-controlled sport exhaust system, with quad stainless-steel tips, has a tone that changes depending on the selected mode (Efficient, Sport, or Sport+). Additionally, the M Sound button can soften the exhaust tone for a more understated note.

The M5 CS builds on the M5 Competition Package's offering when it comes to chassis and suspension tuning. There are stiffer engine mounts, firmer springs, a 0.2-inch lower ride height, increased front negative camber, a firmer rear anti-roll bar, and tow-link ball-joint mounts. There has also been furtherspring and Dynamic Damper Control tuning.

Standard mixed-size non-runflat high-performance tires measure 275/35R20 at the front and 285/35R20 at the rear and are fitted to Gold Bronze 20-inch M forged Y-spoke wheels. Pirelli P Zero Corsa tires are available at no cost.

This car is the first time BMW has put four-passenger seating in a M model in combination with M carbon sport seats up front and two bucks seats for rear passengers. Headrests on all four seats are imprinted with the map of Nurburgring's Nordschleife.

The interior of the car has black Merino leather with Mugello red accents and contrasting red stitching. The M Alcantara steering wheel has a perforated section with red background and lightweight carbon-fiber shift paddles with matching red trim in the cut-outs and on the back panels. Alcantara is also used for the headliner.

The lightweight black Merino leather center console cover with red double stitching replaces the traditional armrest and together with the absence of the armrest area tray helps to further reduce weight. Red "CS" badging can be seen on the instrument panel and between the rear bucket seats. The M seat belts feature BMW M tri-color stitching and the "M5" badge also appears on the velour M floor mats with bespoke piping and in the illuminated "M5 CS" badge on the door sill finishers.

Pricing for the car will be announced at a later date. The M5 starts at $103,500. Expect the limited edition model to be priced higher.

The Lamborghini Sián is one of the most expensive cars in the world. The Italian automaker is only making 63 of the models, with just three allocated to U.K. customers.Lamborghini London, operated by the H.R. Owen Group, took delivery of two of the models, and has had them take part in a photo shoot that reveals their full specifications.

Each Sián is individually styled by their owner, working with Lamborghini's design centre and Ad Personam personalization department. The lighter colored model is finished in a Grigio Nimbus paint job with exposed carbon weave roof and Rosso Mars accents, complemented by a Nero Ade interior with Rosso Alala contrasts.

The darker Sián has Nero Helene colored bodywork that is complemented by an exposed carbon fiber bonnet, front lamp inserts fenders, and engine cover. The car's highlights are finished in Oro Electrum, which is also used within the alloy wheels. This owner has opted for bespoke Pirelli tires with white detailing. The car's cabin has Nero Ade base leather and Oro Electrum stitching and highlights.

Both models are powered by a 6.5-liter V12 engine that is paired with a 48-volt battery to deliver 819 horsepower. The car can get from zero to 62 mph in 2.8 seconds and has a top speed of 217 mph. That makes it the most powerful and fastest accelerating Lamborghini every produced.

Traditional electrified vehicles have heavy battery storage below the floor of the car. Instead, the Sián uses a lightweight supercapacitor that is fully charged every time the vehicle brakes. The e-motor and supercapacitor system weighs in at just 34 kilograms total, making it three times lighter than a battery storing the same power.

The owners of the vehicles have yet to be disclosed.

If you can't afford a Lamborghini Sián but still want one at your home, you can opt for the LEGO Technic version.
