Here is the first logic grid puzzle I’ve designed in about 15 years, written for the XKCD forums. I normally don’t post language-based puzzles but the forum only allows text posts for new users. The community at logic-puzzles.org has worked this one out. Well Done BlackFiresong. See the full article for spreadsheets and solutions.

# Clues

- Every team whose name has an adjacent pair of identical letters is associated with an odd-numbered car.
- For every driver whose name has fewer than three vowels:
- The difference between the qualifying position and final position is odd.
- The sum of the qualifying position, final position, and car number is a prime number.

- For the driver from Germany:
- Car number < qualifying position < final position.
- The sum of these three numbers is a prime number.

- For the Red Bull driver:
- Car number > qualifying position > final position.
- The sum of these three numbers is a prime number.

- For the driver from Norway:
- Qualifying position and final position are the same.
- The sum of the qualifying position, final position, and car number is a prime number.

- For the driver from UK:
- The sum of the qualifying position, final position, and car number is 10.

- Daniel doesn’t drive for Haas.
- Daniel is not from Norway.
- If you were to arrange the list of teams and the list of countries in alphabetical order and place them side by side, there would be no correlations. (The alphabetically first team is not from the alphabetically first country, second team is not from the second country, etc.)
- If you were to arrange the list of names and the list of countries in alphabetical order and place them side by side, there would be exactly two correlations.
- Sebastian’s final position is divisible by 3.
- Japan’s qualifying position is divisible by 3.
- Sebastian is not from the UK.
- Ferrari is not from the UK.
- Romain is not in car number 1.
- Either Nico or Kimi is from the USA.
- The McLaren team placed neither 1st nor 6th in the qualifying round.
- Mercedes is not driven by Max.
