Kaitou Tenshi Twin Angel: Kyun Kyun☆Tokimeki Paradise!!

Every five years, an exhilarating race called Redline is held, and the universe's most anticipated competition has only one rule: that there are none. Racers are pushed to their absolute limit—a feeling that daredevil driver JP knows all too well. Having just qualified to participate in Redline, he is eager to battle against the other highly skilled drivers, particularly the beautiful rising star and the only other human that qualified, Sonoshee McLaren. But this year's Redline may be far more dangerous than usual—it has been announced to take place on the planet Roboworld with its trigger-happy military and criminals who look to turn the race to their own advantage. However, the potential danger doesn't stop the racers; in fact, it only adds to the thrill. Relying solely on his vehicle's speed, JP prepares for the event to come, aiming to take first place in the biggest race of his life. [Written by MAL Rewrite]

Based on a seinen manga by Kusunoki Michiharu serialised in Young Magazine. The story gets its roots from the actual street racing that occurs on Tokyo's Shuto Expressway, one stretch of which is known as the "Wangan", literally meaning "bay side" (although it is generally used to refer to the freeway), the longest, straightest road in the entire country. Of course, there's also lots of traffic to contend with, including a fair number of heavy trucks. Because of this, the action is inherently hazardous, and wrecks are common. Blown engines are also a frequent hazard, especially with the extreme-high power engines. One day, Akio Asakura, a third year high school student, is driving his Fairlady Z (Z31) and is challenged by Tatsuya Shima, a doctor, in his black Porsche 964 Turbo (nicknamed the "BlackBird"). With a friend in the passenger seat and two girls in the back, Akio pitifully tries to win, but is defeated. Determined to become faster, he goes to the junkyard to buy parts for his car, when he sees a pristine, unscratched midnight blue Fairlady Z (S30) in the junkyard. Intrigued as to why such a machine is about to be junked, he buys it. He soon finds that the car is unnaturally fast due to a tuned L28 engine, bored and stroked to 3.1 liters combined with twin turbos, which produces 620bhp. He also finds that all of the car's previous owners had unfortunate accidents in it, starting with the first owner's death. The manga follows Akio's various encounters, though the central plot revolves around his constant battle with the BlackBird for superiority. (Source: AniDB)

Tomoe Shiro, a formidable racer with a very promising career, experiments a U-turn when a serious accident puts his life at stake. He recovers miraculously though when his heart is replaced with the engine of his own racing car. However, because of that very reason, race regulations demote him to the category of a mere mechanical part of the vehicle and is deprived from the right to participate as a pilot in regular races. Only in a far away colonial planet, along with a multitude of other charismatic pilots also vetoed from participating in regular competitions, will he be given the opportunity to race for his pride and the money of the prize. And so this exciting rally starts!! (Source: Official website)
