styling exercise

BMWがM4 Coupeの外装を発表しました。今回は外装のみでエンジンや内装，シャシーに関する公式な情報は公開されていませんが，記事ではこれをstyling exerciseと表現しています。「外装のみのお披露目」といったところでしょうか。それにしても美しい！（Koyamamoto）

BMW M4 Coupe 2014 revealed
Scorching BMW M4 Coupe is unveiled at Pebble Beach in California, on sale early next year
These are the first pictures of the BMW M4 Coupe - the successor to the BMW M3 Coupe. It will make its public debut at the Pebble Beach Concours d’Elegance, and although it’s officially still a concept, but don’t be fooled – the car you see here is 99 per cent the car you’ll be able to buy in 2014.
… The concept BMW M4 Coupe is being called a styling exercise at this point, so there are no official engineering details on the chassis or engine at present, but there’s still plenty to learn from scrutinising the exterior design.
