Audi TT Roadster (2015) vs Lexus IS 250C (2014)

A dual-clutch transmission (DCT) is an automated manual transmission that allows the driver to control gear-shifts themselves or to let the computer decide. Upshifts are extremely fast, resulting in smooth acceleration, and due to the uninterrupted power flow it also has the benefit of increasing fuel efficiency.

This allows all four wheels to move up and down independently, providing a smoother ride when, for example, going over bumps in the road.

Four-wheel drive is a system where torque is distributed to all four wheels of the vehicle. It is beneficial in some circumstances such as providing increased traction in tricky weather conditions, but is most suited to off-road driving.

Rear-wheel drive benefits from increased traction when accelerating, as the weight of the vehicle shifts to the rear over the drive wheels. The weight of the car is also more evenly distributed, resulting in improved handling.

The basic warranty of a car covers all aspects other than parts which are subject to normal wear and tear, such as windscreen wipers and brake pads. It lasts either a certain number of years or amount of kilometres driven.

The turn radius indicates the smallest circular turn a car can make. With a smaller turn radius it is easier to perform a U-turn in one attempt instead of having to reverse back and forth in order to turn around.

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.

A larger cargo area is more practical as it allows you to transport more things.

The wheelbase is the distance between the center of the front and rear wheels. A longer wheelbase provides the car with more stability and a smoother ride (although a shorter wheelbase can provide more responsive handling).

We consider a shorter length better because a compact chassis is generally easier to maneuver.

The height represents the vertical dimension of the product. We consider a smaller height better because it assures easy maneuverability.

More headroom in the front of the car makes for a more comfortable driving experience, and is especially important for taller people.

The fastest speed that the vehicle can reach.

The time it takes for the car to accelerate from 0-100 kilometres per hour.

The coefficient of drag is one measurement of how well air travels around a vehicle. A lower value means it is more aerodynamic and the engine doesn't have to work as hard. It can result in faster speeds and lower fuel consumption.

Torque is a measurement of an engine’s power, closely related to horsepower. More torque indicates a more powerful vehicle and is also a good indication of its acceleration.

Fuel economy is a measurement of fuel efficiency, based on how far you can travel with a certain amount of petrol (gasoline). A lower fuel economy means the car will be cheaper to run.

Horsepower is the most common unit for measuring the power of an engine.

Fuel economy is a measurement of fuel efficiency, based on how far you can travel with a certain amount of petrol (gasoline). A lower fuel economy means the car will be cheaper to run.

A turbocharger compresses the air entering the cylinders, allowing more air (and therefore more fuel) to be added - resulting in a more powerful explosion. This leads to an increase in horsepower without increasing the size and weight of the engine.

Fuel economy is a measurement of fuel efficiency, based on how far you can travel with a certain amount of petrol (gasoline). A higher fuel economy means the car will be cheaper to run.

ISOFIX (also known as LATCH) is a standard system of attachment points for child safety seats, allowing them to be fitted quickly and safely.

Airbags are designed to cushion occupants in the event of an impact. The standard number is around six, but some cars now incorporate additional ones, such as knee airbags, side airbags, and side curtain airbags.

Height-adjustable seat belts permit passengers of different sizes to move the seat belt up or down for improved comfort. They are also especially useful for increasing the safety of children.

With more USB ports, you are able to connect more devices.

The vehicle has a tracking system that utilizes GPS, allowing you to locate it in case it is stolen.

A smart key is a wireless key that offers several benefits over a traditional key. For example when you approach the car the doors will automatically unlock, and you can turn the engine on with the press of a button.
