Porsche Cayman S
Requirements to unlock the car: This vehicle is available from the game beginning.
Porsche Cayman S is a very good "beginning" car, because it has perfect control. Other parameters are worse, so if you want to win some later events, you'll be forced to upgrade this vehicle or decide to buy another one.
Dodge Challenger SRT8
Requirements to unlock the car: Achieve Rank 2.
Price: 30000 speedpoints
The main advantage of Dodge Challenger is that it is much more durable than the starting car in the Racer career. Unfortunately it has quite bad parameters and it is hard to control it, so you can use it only in easiest races.
Aston Martin Vanquish
Requirements to unlock the car: Achieve Rank 3.
Price: 32500 speedpoints
Aston Martin Vanquish is much better proposal than Dodge Challenger. It is slightly more expensive and despite the same strength and durable values it has better acceleration and control.
BMW M3 GTS
Requirements to unlock the car: Achieve Rank 4.
Price: 37500 speedpoints
BMW M3 GTS is better than Aston Martin Vanquish only with top speed. However this car is less durable, so it won't do well in Hot Pursuit events for example.
Ford Mustang GT
Requirements to unlock the car: Achieve Rank 5.
Price: 42500 speedpoints
Ford Mustang GT is interesting proposal if you need a car which can't be easily destroyed because of police or other racers attacks. Unfortunately this vehicle has very poor acceleration and difficult control.
Chevrolet Corvette Stingray
Requirements to unlock the car: Achieve Rank 6.
Price: 50000 speedpoints
Chevy Corvette Stingray has parameters similar to Mustang GT. The only significant difference is that Chevy has better acceleration, so it won't stay behind even in more difficult races. Unfortunately it is not easy to control it.
Mercedes-Benz SLS Black Series
Requirements to unlock the car: Achieve Rank 7.
Price: 57500 speedpoints
Frankly speaking Mercedes is not an attractive proposal, because it has slightly better parameters than Corvette, but it is harder to control it. But this is not the only problem - it is also less durable than its American competitor.
Porsche 911 GT3
Requirements to unlock the car: Achieve Rank 8.
Price: 67500 speedpoints
Porsche is 10,000 speedpoints more expensive than Mercedes SLS but it is more useful car. 911 is controlled easier than Mercedes and it has slightly better acceleration. But you have to deal with average durability of this car.
Audi R8 Coupe V10 plus
Requirements to unlock the car: Achieve Rank 9.
Price: 77500 speedpoints
Audi is a good car for time trials and other similar events, because it has satisfactory performance and very good control. Unfortunately this car is not much durable so it won't be good in hot pursuits.
Ferrari 458 Spider
Requirements to unlock the car: Achieve Rank 10.
Price: 87500 speedpoints
Ferrari has brilliant acceleration and it is very fun to control it, so it is perfect vehicle for all events where you have to get from point A to point B. unfortunately this car has an average durability.
Lamborghini Gallardo LP 570-4
Requirements to unlock the car: Achieve Rank 11.
Price: 100000 speedpoints
Lamborghini is in my opinion an unattractive proposal, losing to the previous car from the main list in all categories except top speed. Especially problematic are low values of durability and strength, so this car is not good in hot pursuits.
McLaren 12C Spider
Requirements to unlock the car: Achieve Rank 12.
Price: 117500 speedpoints
McLaren 12C Spider is a very successful design. This vehicle will be a good use mainly in standard races and time trials and that's because it is fast and easy to control. Slightly worse is with the durability but you can live with it.
Requirements to unlock the car: Achieve Rank 13.
Price: 135000 speedpoints
Ford GT is worse proposal than McLaren 12C, because although it has slightly higher top speed, it also has worse acceleration. But this is not the only difference - this car has worse control than mentioned British construction.
Ferrari 599 GTO
Requirements to unlock the car: Achieve Rank 14.
Price: 155000 speedpoints
Ferrari 599 GTO has a very high top speed value, as well as acceleration and control, making it ideal choice for racing. Unfortunately this vehicle is not very durable so it is not dealing well with police cars attacks.
Porsche 918 Spyder
Requirements to unlock the car: Achieve Rank 15.
Price: 177500 speedpoints
Same as with Ferrari described above, this vehicle is ideal for time trials for example, because it has excellence performance and it is easy to control. But the price for these advantages is unfortunately outrageously low durability.
Requirements to unlock the car: Achieve Rank 16.
Price: 202500 speedpoints
Ferrari F12 in my opinion is the best car available in the game. This vehicle is not only fast and easy to control, BUT also more durable than its competitors available later on in the career mode. It makes this car universal vehicle, perfect both for races and time trials, as well as for hot pursuits.
Lamborghini Aventador LP 720-4
Requirements to unlock the car: Achieve Rank 17.
Price: 235000 speedpoints
Aventador has better performance than F12 described above, making earning gold medals easier even in more difficult races and time trials. Unfortunately this car is less durable, so it is not as good in duels with police cars, as F12.
Requirements to unlock the car: Achieve Rank 18.
Price: 270000 speedpoints
Veneno is slightly better than Aventador in acceleration, but it is not as good as it goes to control. But more serious problem with this vehicle is that it has very low durable and it is completely useless in hit pursuits.
Ferrari Enzo Ferrari
Requirements to unlock the car: Achieve Rank 19.
Price: 310000 speedpoints
Ferrari Enzo is a very interesting proposal. This model is definitely better than other cars from the end part of the career mode in matters of durability and strength, but it is not as good as F12. But it is slightly faster than competitive Ferrari model.
Requirements to unlock the car: Achieve Rank 20.
Price: 355000 speedpoints
Huayra trumps all other cars in Racer career mode in the category of top speed. It is also good as we speak about acceleration and control. But unfortunately the price for this excellent performance is very low durability.
Requirements to unlock the car: Achieve Rank 21.
Price: 410000 speedpoints
McLaren P1 is an ideal vehicle for winning time trials and standard races, offering astonishing performance and being easy to control at the same time. But I do not recommend using it for hot pursuits because its durability is at the surprisingly low level.
