A fuel blend comprised of 85% methanol and 15% gasoline. While at one time an alternative fuel source to help combat gasoline shortages, it is no longer used because fumes produced from methanol in a combustion engine are highly poisonous and may pose a serious risk to occupants.


The particular name of a vehicle’s manufacturing company or production unit. Vehicles are typically referred to in a “Year-Make-Model” denotation within the automotive industry. These can include major manufacturers or their specific subsidiary brand such as Ford, Chevrolet, and Volvo.

Manifold Heat Control Valve

A thermostatic installation which provides a vehicle with a faster capacity to warm up when starting in more extreme cold temperatures. Heat from a vehicle’s exhaust is routed to the engine’s intake manifold to better promote fuel vaporization. This action reduces warm-up time by providing an additional source of heat to reach faster vaporization temperature thresholds for fuel.

Manual Extending Mirrors

Side view mirrors which can be manually adjusted to move further away from the vehicle chassis for added visibility. This feature is often equipped on larger trucks and SUVs as the increased visibility is primarily used to see objects being towed behind the vehicle.

Manual Transmission

A transmission system where the vehicle operator manually shifts the gears by activating a clutch and moving a gear selector to the desired gear. Properly operated manual transmission vehicles can often increase fuel efficiency compared to their automatic counterparts.

Manufacturer’s Engine Code

Alphanumeric codes assigned to engines by the vehicle manufacturer which are used to distinguish them from other engines. This prevents confusion when engine builds are highly similar in vehicle models.

Map Storage

Electronic storage medium where a vehicle’s internal navigational maps are stored for access when needed. Media types include a memory card, hard drive, or CD/DVD drive depending on the system.

Marketing Support

Manufacturer-provided programs used to help reinvigorate vehicle buying, stimulate dealer sales, or enhance a dealer’s marketing tactics for improved sales potential. Support may be provided in situations where a manufacturer wants to move specific vehicles off dealer lots to make room for new models. It may also be used as an added promotional tool to reach targeted sales goals within given timeframes.

Massaging Seats

Vehicle seats equipped with an electronic massage system within the seatback. Frequently included as a luxury amenity, most massaging seats offer a variety of selectable options to adjust settings to an occupant’s preferences.


The “Maximum Horsepower Revolutions Per Minute,” or the speed at which an engine can generate its maximum amount of total horsepower.

Max Torque RPM

An engine’s exact speed where it can generate the maximum possible level of torque. This amount will differ based on a vehicle make, model, year, and engine condition.

Maximum Cargo Capacity

Measurement which provides the total actual amount of available cargo space within a vehicle. Many SUVs, crossovers, and vans allow seats to either be removed or folded down to increase storage capacity. This measurement reflects the total volume of space when every seat is folded or removed.

Memory Settings

Preset settings and positions for multiple elements within a vehicle. Depending on the automobile, an internal memory can save settings for power seat position, mirror positioning, steering column height and orientation, audio system adjustments, heating and air conditioning, and other elements. Vehicles equipped with this feature can switch between saved profiles for different drivers for convenient readjustment of preferred settings and positioning.


A vehicle which is propelled forward through rear-wheel drive due to specific engine placement. The engine is located forward of the rear axle and behind the front axle. This design can improve handling for sports cars and coupes, but it often sacrifices rear cabin passenger space to accommodate the centralized engine placement.

Mileage Allowance

The total number of miles a lessee is permitted to drive throughout the term of a vehicle lease. Mileage allowance limitations typically range from 10,000 to 15,000 miles per year. However, a total sum of permitted miles may also be determined without annual limitations. Any excess miles driven past the allowance will incur excess mileage penalties determined and outlined in the leasing agreement.


The specific vehicle brand or type which is identified by a name, number, and additional denotations for style, trim, or engine type. In the automotive “Year-Make-Model” denotation, this allows for the accurate identification of vehicles which may have similar models but differing equipped features and amenities.

Model Year

The calendar year designation of a vehicle model reflecting the manufacturer’s specific time when it was released for sale. The year is typically denoted first in the “Year-Make-Model” designation within the automotive industry.

Money Factor

Also known as a vehicle’s “Lease Factor” or “Lease Fee,” a term which expresses the interest rate which is used throughout the term of a lease to determine the total monthly payment by the lessee. The number is calculated by the specific APR divided by 2,400. An example would be a 5.3% APR divided by 2,400 yielding a .0022 money factor. This factor is often used in leasing situations where the total residual value of a leased vehicle may fluctuate, leading to adjustments in monthly payments.

Monroney Sticker

Commonly known as a vehicle’s “Window Sticker,” this legally required sticker is posted on all newly produced vehicles from manufacturers. It provides a breakdown of all the major components consumers should know about that particular vehicle. Information on the sticker includes the following: MSRP (not counting additional dealer fees), standard equipment on the vehicle, specifications for both the engine and transmission, optional features and equipment with the prices, both highway and city MPG ratings from independent EPA testing, warranty coverage, and crash test safety ratings independently determined from a National Highway Traffic Safety Administration (NHTSA) analysis. This information is a highly important component of a consumer’s right to know and understand all the elements a prospective vehicle may offer. It’s another tool which consumers can use to learn about their vehicle and make a fully informed buying decision. Legal requirements prevent any misinformation or withholding of vital details about a vehicle that may influence that buying decision.

Monthly Payment

The total amount of principal and interest a vehicle owner or lessee must pay each month under the specific terms of the financing or leasing agreement. This amount varies based on vehicle and dealer specifics as well as the creditworthiness of the owner or lessee.


Common shorthand for “Miles Per Gallon,” the amount of miles a vehicle can drive per gallon of fuel during typical operating conditions. These measurements include both city MPG ratings and highway MPG ratings to reflect the differences depending on the driving environment.


Acronym for “Manufacturer’s Suggested Retail Price,” and also known as the “Sticker Price,” this is the manufacturer set pricing for a vehicle. MSRPs usually first show the base list price, but a Window Sticker indicates available features and options and the additional costs to equip them. This price does not include any dealer fees, taxes, or other charges.
