Around here, we throw around car tech jargon faster than a Lamborghini Aventador can sprint from 0-60 mph (that?s 2.6 seconds in case you?re wondering). But we know not all of you out there are hardened gearheads and grease monkeys. So in order to get you up to speed, we?ve come up with this handy glossary of common and not so?common?car tech terms.
Grab your keys, slap on your riding gloves and goggles and get ready to leave all that confusion firmly in your rearview.
4WD
Abbreviation for Four-Wheel Drive.
ABS
Anti-locking braking system (ABS) is an automated safety system that helps a car?s wheels continue to rotate during heavy braking, thus preventing a driver from losing control of their vehicle because of uncontrollable wheel skidding.
ACC (Adaptive Cruise Control)
Adaptive Cruise Control is a form of cruise control that automatically (without any driver input) brakes and accelerates to match the flow of traffic. Some ACC systems can even come to a complete stop and accelerate from a standstill.
All-Wheel Steering
A car equipped with All-Wheel Steering means that the rear wheels can turn in the direction of the front wheels, which typically improves handling dynamics. Acura?s new RLX flagship sedan features a proprietary Precision All-Wheel Steering system that takes this concept further by allowing the wheels to point inward to help improve braking.
Automatic
Type of transmission that automatically changes gears instead of making the driver shift through them manually.
Autonomous vehicles
Autonomous vehicles refer to vehicles that can operate without any input from drivers whatsoever. This generally means that a car can turn, accelerate, and brake without the need of a driver at the wheel.

Blind spot monitoring is a technology that scans a vehicles blind spot for objects (usually cars). If detected, a warning ? typically in the form of a visual cue on the vehicle?s door pillar ? lights up. Some vehicles even provide audible warnings if a turn signal is activated when another car is present in a blindspot.

Keyless entry
Keyless entry denotes a car that can be unlocked without physically inserting a key to unlock the doors. Typically, you must have the key fob on?your?person for the system to work.
KERS
Short for kinetic energy recovery system, KERS gathers (recovers) energy created during braking and stores it for use during acceleration. The technology has yet to make it into production vehicles but can be found in Formula One cars.

Li-ion battery
An abbreviation for lithium-ion battery, a type of rechargeable battery used to power electric cars and hybrids.
Limited Slip Differential
Cars with limited slip differentials can send rotational power to both wheels when one is raised off the ground or experiencing slippage. Standard or ?open? differentials cannot perform this task, so if one wheel is raised off the ground it will spin while the wheel in contact with the ground will remain stationary.

When you take your vehicle to the DEQ, they plug their computer into the ODB II port. App makers are also making use of this port to inform drivers about what their car is doing.
Open XC
Open XC is the architecture Ford uses to let apps ?talk? to a car?s onboard systems.
Oversteer
Driving characteristic where a car turns more sharply than intended, possibly causing the car to spin out of control. Oversteer is commonly associated with rear-wheel drive cars.
Push button Ignition
Push button ignition (also referred to as push button start) is any system that allows you to start a car by pressing a button instead of physically inserting and turning a key in the ignition.

SUV
Short for Sport Utility Vehicle.
Supercharger
An air compressor designed to further increase pressure, temperature, and density of air supplied to a car?s engine. Higher air pressure in an engine, along with matching?increased?fuel flow can greatly increase engine performance.
Tachometer
Tachometers are typically placed in a car?s instrument cluster and measure RPMs (revolutions per minute), which is the number of times an engine?s central crankshaft rotates.
Touchscreen
Similar to what you?d find on a smartphone, a touchscreen is any interactive screen that provides some sort of tactile feedback when pressed. Touchscreens in automobiles are typically used for in-car entertainment and navigation systems.
Torque
Torque is the pulling power of a vehicle, which is often crucial for trucks hauling heavy loads. It?s the twisting force created inside an engine by all those rotating parts. Generally, cars with higher levels of torque also accelerate faster, which is why sports cars typically have greater torque levels. Torque is measured in pound-feet (lb-ft).
Transfer Case
Often found in both four-wheel-drive and all-wheel-drive vehicles, a transfer case receives power from the transmission and sends it to both the front and rear axles.
Transmission
A car?s transmission ?transfers? power from the engine or motor to a drive mechanism, often a live axle, through a series of gears and clutch.

V12s are largely uncommon and typically found in flagship sedans (BMW 7 Series, Audi A8, Mercedes-Benz S Class) and outlandish exotics like the Enzo, Pagani Zonga, and McLaren (you know, back when McLaren wasn?t getting carried away with letters and numbers).
V16
A V16 engine is any engine with 16 cylinders arranged in the shape of a ?V? with two banks consisting of eight cylinders each. Modern V16s are rare and have typically been restricted to concept cars and limited run vehicles from smaller boutique manufacturers.
Wheelbase
Wheelbase is simply the distance between the centers of both the front and rear wheels.
