Modern Car Tech Features Explained
Automotive technical terms can be challenging to comprehend. Continuing our 3-part blog series on modern vehicle terminologies, we’re still on a mission to simplify some of the automotive jargon that might boggle your mind whenever you hear them.
From fuel efficiency innovations to advanced safety features, the automotive world is evolving, and knowledge is the key to embracing these changes confidently. In Part 1 and Part 2 of the series, we curated a glossary of terms and acronyms to help you cut through the jargon and talk the talk.
In Part 3, we continue decoding the last set of auto-related tech and terminologies widely used in automotive settings. Let’s explore more together.
5MT: 5-Speed Manual Transmission
This refers to a type of gearbox in a vehicle with five forward gears and requires the driver to manually shift between them using a clutch pedal. Manual transmissions allow the driver more control over gear selection and enhance the driving experience for those who enjoy a more engaged driving style.
A4: 4-Speed Automatic Transmission
It’s a gearbox that automatically shifts between four gears without requiring manual input from the driver.
A5: 5-Speed Automatic Transmission
A 5-speed automatic transmission is an automatic gearbox with five different gear ratios, allowing for efficient shifting and improved fuel economy.
A6: 6-Speed Automatic Transmission
This gearbox type is equipped with six forward gear ratios. These transmissions automatically shift gears based on factors such as load, speed, and throttle position.
AHC: Automatic Height Controller
A system or device that automatically adjusts the height of a component or vehicle based on specific conditions. For instance, it can regulate the vehicle’s suspension height to adapt to different road conditions or load variations.
AMT: Automated Manual Transmission
An AMT is an automotive transmission that combines manual and automatic transmission features.
ATLS: Automated Truck Loading Systems
This refers to a system that automates the process of loading goods onto trucks. The technology streamlines the loading process, making it faster, safer, and more efficient in logistics and warehouse operations.
DOHC: Dual Overhead Cam
DOHC is an engine design with two camshafts in each cylinder head. These camshafts control the opening and closing of valves, resulting in better airflow, increased horsepower, and improved performance compared to an SOHC (Single Overhead Camshaft) engine.
DVVL: Discrete Variable Valve Lift
This engine technology employs a lobe with an electronically adjustable centre section to reduce valve lift. By doing so, it minimises pumping losses and enhances fuel economy.
DRL: Daytime Running Lights
These are front lights that operate whenever the engine is running, enhancing visibility during daylight hours. Often referred to as driving lights, manufacturers utilise them to enhance the car’s front appearance.
FDC: Fixed Displacement Compressor
This type of compressor in air conditioning systems operates at a constant displacement, providing a consistent refrigerant flow regardless of the cooling demand.
FSH: Full-Service History
When purchasing a pre-owned vehicle, this pertains to the documented history of services completed at intervals specified by the manufacturer.
GVW: Gross Vehicle Weight
Gross vehicle weight indicates the maximum weight a motor vehicle is licensed to carry and tow. This weight includes the vehicle’s curb weight, all occupants, and any cargo it carries.
GVWR: Gross Vehicle Weight Rating
It refers to the weight your vehicle is designed to carry. Manufacturers calculate this weight rating by assessing the vehicle’s structural strength, engine power, suspension, and braking systems.
MT: Manual Transmission
This is a type of transmission in vehicles where the driver manually selects and engages the gears using a gear shifter and a clutch pedal.
TBI: Throttle Body Injection
A fuel injection system where fuel is injected directly into the throttle body, regulating the air-fuel mixture before entering the engine’s combustion chambers. Nowadays, more advanced systems like multi-port injection (MPI) and gasoline direct injection (GDI) are prevalent, but TBI remains a reliable and straightforward method for fuel delivery.
VDC: Variable Displacement Compressor
This air conditioning compressor can adjust its displacement (unlike fixed-displacement compressors), allowing for variable cooling capacity based on the vehicle’s requirements. Many modern cars use VDCs to enhance air conditioning performance while minimizing energy consumption.
That was Part 3 of our series on automotive terminologies. We hope you’re well-equipped to make informed decisions about vehicles and their technologies. We invite you to explore the diverse range of Group1 vehicles and witness firsthand the cutting-edge features that redefine your driving experience.
