Q label marks advent of new designs

Following a new naming system, Infiniti has unveiled its 2014 lineup.

According to the new system, all Infiniti sedans and coupes are prefixed with the letter Q, while its SUVs will be labeled QX. After the letters, a double-digit number is used to indicate the different classes of the cars.

The former G sedan is now called Q50, while the G coupe and convertible is now the Q60. The luxury Q70 has replaced the M sedan at the top of the lineup.
