Audi Q5 [2013-2018] 2.0 TDI quattro Premium Plus

Specifications

• Engine & Transmission
  Engine

  1968 cc, 4 Cylinders Inline, 4 Valves/Cylinder

  Timely services will keep a motor efficient and in top shape.

  Engine Type

  inline diesel engine with common rail injection and exhaust gas turbocharging.

  The official title given by the manufacturer in terms of the name of the engine, the displacement and the number of cylinders.

  A bigger displacement and more than four-cylinders generally indicate a performance-oriented engine.

  Fuel Type

  Diesel

  All cars in India either run on petrol, diesel, CNG, LPG or electric power.

  Max Power (bhp@rpm)

  174 bhp @ 4200 rpm

  Gives a good idea of the performance of the vehicle under full thrust. A higher figure here usually means a higher top speed as well.

  Higher the power, the peppier the engine but it can also affect fuel economy.

  Max Torque (Nm@rpm)

  380 Nm @ 1750 rpm

  Relates to in-gear acceleration. A higher figure here means better roll-on acceleration, fewer gear shifts, and possibly better fuel efficiency.

  The more torque at low RPM range makes the engine feel more responsive. It also allows the engine to run smoothly without too many gear changes.

  Mileage (ARAI)

  12.8 kmpl

  This is the maximum fuel efficiency that an engine gives. All numbers are provided by the manufacturer based on tests conducted and specified by the standards of the ARAI (Automotive Research Association of India)

  Such fuel efficiency attained while driving in special conditions makes it unlikely to get it in real-world conditions

  Drivetrain

  AWD

  Cars come with different drivetrain configurations depending on the segment.

  Front-wheel drive (FWD) is most common in mainstream cars while expensive cars or SUVs come with rear-wheel drive (RWD) or all-wheel drive (AWD).

  Transmission

  Automatic - 7 Gears

  Type of transmission used to transfer power from the engine to the wheels

  A manually operated transmission is the most popular type, thanks to its simplicity and low cost. Varied types of automatic transmissions are also available.

  • Valve/Cylinder (Configuration)
    4

• Dimensions & Weight
  Length

  4629 mm

  The length of the car decides its segment. In India, cars that are less than 4 metres in length enjoy reduced excise duties.

  

  • Length: 4629

  Longer length results in more cabin space. It also adds to straight line stability.

  Width

  1898 mm

  A car's width is defined as its widest point without its mirrors.

  

  • Width: 1898

  Although more width gives you more lateral space inside the cabin, it makes the car more difficult to park in narrow spots.

  Height

  1653 mm

  The height of the car denotes the highest point of the vehicle from the ground.

  

  • Height: 1653

  Taller the car, the more headroom there is on offer inside the cabin. However, a tall boy stance also affect the car’s centre of gravity which can cause more body roll.

  Wheelbase

  2807 mm

  The space between the center of the front and rear wheels.

  

  • Wheelbase: 2807

  The longer the wheelbase, the more space there is inside the cabin.

  Kerb Weight

  1830 kg

  The total weight of the vehicle with all the standard equipment and all the required fluids.

  A lightweight car will always be more efficient and easier to manoeuvre whereas a heavy car would give you a sense of solidity while driving.

• Capacity
  Doors
  5 Doors
  The number of doors define the category of car. For example – four door means sedan, two-door means coupe while five-doors usually refer to a hatchback, MPV or an SUV.
  
  • Doors: 5
  Seating Capacity

  5 Person

  The number of people that can be seated comfortably in the car, which has also been mandated by the car manufacturer.

  No of Rows

  Smaller cars usually have two rows which can seat five, but some SUVs and MPVs have three rows and can seat around 7-8 passengers.

  Fuel Tank Capacity

  75 litres

  The official volume of the fuel tank of a car, usually denoted in litres.

  If a car has a large fuel tank, it can cover long distances without refuelling.

• Suspensions, Brakes, Steering & Tyres
  Front Brake Type

  Disc

  Most of the vehicles sold in India get ventilated or non-ventilated disc brakes upfront.

  - The ventilated discs are more popular thanks to them providing better stopping power and it also works well in hot conditions.

  Rear Brake Type

  Disc

  In affordable cars, drums brakes are fitted at the rear as they are cost effective.

  Disc setup at the rear is now getting more popular as cars are getting faster in the real world.

  Minimum Turning Radius

  5.8 metres

  The official kerb-to-kerb minimum radius a car takes to complete a 180-degree turn.

  Shorter the turning radius, the lesser space you need to make a tight turn or to take a U-turn.

  Spare Wheel

  Alloy

  Important in a country with varying quality of roads, spare wheels ensure one doesn’t get stranded when one of the main tyres gets damaged.

  Select premium car models feature space savers (smaller than the stock wheels) to save on boot space.

  Front Tyres

  235 / 65 R17

  The profile/dimension of rubber tyre that fits on the front wheels.

  Rear Tyres

  235 / 65 R17

  Yes

  An electronic system that redirects braking forces among the four brakes to stop the car as quickly and stably as possible

  Brake Assist (BA)

  Yes

  Differential Lock

  No

  Locking differentials split power/torque evenly among both tyres on an axle.

  In off-road vehicles, locking differentials allows for better traction when one of the wheels is in the air, in FWD/AWD cars allows for better corner traction and in RWD sports cars allows for drifting around corners.
