If you’re anything like the typical car-shopper, then you likely don’t speak automotive jargon, and you probably have no idea what a dual-clutch transmission is or how it could benefit you. It’s normal. However, knowing the details may help you make a more informed decision the next time you’re comparing spec sheets.
Let’s talk basics first. In a manual vehicle, in order to change gears, the operator must depress a clutch pedal that briefly disconnects the engine from the transmission. For this reason, it’s common to feel that sort of lurching motion between levels.
In a dual-clutch transmission, however, there are...you guessed it...two couplings controlled not by pedals but electronically through the internal CPU. Because the two units operate a separate set of gears, the transitions can happen fluidly without interrupting power flow.Â
The result and benefits to you are quicker, smoother changes, as well as better efficiency (it's rated at 24 MPG in the city and 33 MPG on the highway). Want to learn more about this feature? Stop by our dealership today to test drive our dual-clutch equipped INFINITI QX30.

Variable Valve Event and Lift — commonly shortened to VVEL on individual specs sheets — is an innovative timing control system developed by Nissan and adapted to the automaker's luxury INFINITI vehicles.
As seen in the 2018 Q70, VVEL technology utilizes hydraulic-operated timing processes combined with electronically managed consumption functions to simultaneously improving fuel efficiency while also reducing emissions. For example, thanks to the proprietary mechanics, the brand’s flagship sedan is able to earn an impressive 18 MPG in the city and 25 MPG on the highway.
In a standard engine, air is restricted from entering the intakes for longer intervals. However, a VVEL-equipped powertrain allows air to flow through the wide throttle opening — which, unlike other setups, doesn’t close when the driver depresses the pedal. From there, the oxygen is admitted into the combustion chamber at a more precise rate determined by the intake valves. Because the draft sits directly outside the cell, the throttle response is instant.
