Frequently asked questions
When buying a car, you should consider the following factors:
1. Fuel economy: Ensure you'll be comfortable with the running costs of the vehicle for your day-to-day use.2. Price: Consider not only the purchase price but also associated taxes, insurance costs, and maintenance when budgeting.
3. Ratings: Look to how existing owners of that vehicle feel (such as CarMax's vehicle owner reviews) and also professional services (such as RepairPal reliability ratings).
4. Dimensions: Ensure the exterior size of the vehicle is something you can easily park (whether in a garage, a lot, or on the street) and that the interior size will fit your lifestyle (such as adequate space for passengers or car seats).
5. Technology: Check out the technology features (both infotainment and driver assistance features) that can enhance your driving experience.
Remember, the right car for you depends on your specific needs and lifestyle.
Both AWD (all-wheel drive) and 4WD (four-wheel drive) send power from your engine to all four wheels of your vehicle in order to take maximum advantage of available traction.
AWD uses a variable connection that your vehicle can adjust on the fly, at any speed, to shift power where it’s needed. 4WD connects your front and rear wheels through a transfer case that splits power evenly, and it's meant to be used at lower speeds and in challenging terrain.
You can learn more in our exploration of the topic: AWD vs. 4WD: What's the Difference?
The choice between a smaller turbocharged engine and a larger naturally-aspirated engine depends on your specific needs and preferences.
A smaller turbocharged engine, like the 1.5L turbocharged three-cylinder engine in the 2022 Nissan Rogue, can provide ample power (201 hp and 225 lb-ft of torque) while achieving good fuel economy (an EPA-estimated 33 mpg combined). Over the last two decades, more and more manufacturers have adopted smaller engines equipped with turbocharging to deliver better fuel economy.
On the other hand, a larger naturally aspirated engine, like the V8 engine in the 2021 Lexus RC F, can provide a significant amount of power (472hp).
Ultimately, your choice would depend on what you value more: fuel efficiency or power.
