The Shelby Cobra 427 S/C is a rare classic sports car also known as the AC Cobra 427. "S/C" stands for "Semi-Competition".

With assistance from Ford and AC Cars, the team at Shelby American modified the existing AC chassis design to accommodate the big block engine. The completed design was called the mark III chassis was manufactured with larger and wider spaced chassis rails. Shelby ordered 100 of these from AC Cars.
Due to the weight of the engine the brakes and suspension were also upgraded. The body was featured prominent wheel arches to fit wider magnesium wheels and tires. Competition features included an oil cooler, side exhausts, large fuel filler, 42-gallon fuel tank, front jacking points and a roll bar.
The Shelby Cobra 427 S/C appears as a special event car in Tier 3. Added in Update 1.1.0, the last update of Asphalt 7: Heat, it is the second highest-ranked car in Tier 3, just behind the Lamborghini Sesto Elemento. The lending price, at 527,000 cash, makes it very expensive for a Tier 3 car, though the Sesto Elemento is more expensive (875,000). It is generally a mere stat upgrade for the Alfa Romeo 8C Competizione or the Aston Martin V12 Vantage.
The Cobra has one of the highest acceleration statistics in Class B when fully upgraded. It also possesses an extremely high Tuning Kit bonus, which is only beaten by the Honda Integra Type-R, in Class B.
In fact, the Cobra is actually still faster than the Honda Integra Type-R at MAX + PRO with a Tuning Kit (the Cobra is one rank higher with a ten rank lower Tuning Kit bonus), because the Honda Integra Type-R is nitro-based, and thus, has a lower total top speed. In Asphalt 8: Airborne, cars with high nitro statistics usually have low total top speeds, from classes C to S. However, this trend is the opposite in Class D, where the Ford F-150 has the highest relative (compared to similarly-ranked cars) MAX + PRO sans Tuning Kit speed of any non-Elite car in the entire game.
Due to the above information, the Cobra has the most highly augmented performance of any non-Elite car in Class B. However, being only located halfway through the class and not featured in many Time-Limited Events, it is unfavorable to fully upgrade the Cobra.
The Cobra's acceleration at the default level, especially without nitro upgrades, is not extreme, but still very good. The Cobra also has very good handling at the default level, which is made even stronger with upgrades. The only two things that the Cobra lacks are the ability to drift well and the ability to stay nitro-boosted for long periods of time. The Cobra's abysmal drifting radius can make it a better idea to use handling in many situations.
However, a technique known as a "micro-drift" can be used to help the Cobra take on corners more effectively. This is done by drifting and activating nitro many times during a "single drift", in order to take advantage of the small repositioning that occurs every time a drift occurs. It should be noted that every micro-drift must be done in the same direction, in order for the drift to improve overall.

Due to the Cobra's low starting rank, it is a formidable weapon in Multiplayer.
The Cobra's acceleration and handling are both good at the default level, allowing it to outrun many other cars at the starting line. In addition to this, its speed can get very high with the correct tuning.
Generally, the best tuning for the Cobra is 0500 5050, which results in a speed of ~248 mph (exactly 399 km/h) with Tuning Kit and without tuning kit, it can reach 237 mph (383 km/h). The tune can be taken higher with nitro upgrades.
The Cobra's biggest hidden bonus is its very low top speed weighting. This means that top speed doesn't add too many ranks. The Cobra can reach its maximum raw top speed at a rank of only 1234 (the aforementioned tune), meaning that it is also extremely fast at a low rank, making it even more powerful in Multiplayer.
