2013 BMW Alpina B7 gains 40hp and aerodynamic upgrades
Alpina's 2013 B7, revealed ahead of its Pebble Beach debut, receives a 40-horsepower increase, aerodynamic improvements and a higher top speed, with prices starting at $128,495.
Alpina has unveiled the 2013 B7, its flagship performance saloon based on the latest BMW 7 Series, ahead of a world premiere at Pebble Beach. The updated B7 now produces 540 horsepower, a 40hp increase over its predecessor, along with 538lb-ft of torque. This extra output comes from engine revisions including BMW’s Valvetronic throttle-less intake system. The 2013 Alpina B7 is positioned as an exclusive, high-performance alternative to the standard BMW 7 Series, blending luxury and speed in a full-size executive package.
Introduction and Overview
Engine and Performance Upgrades
The B7’s 4.4-litre twin-turbocharged V8 benefits from the same eight-speed automatic transmission as the 2013 7 Series, but Alpina’s tuning raises both power and torque. The result is a claimed top speed of 194mph for rear-wheel-drive models. The xDrive all-wheel-drive variant is electronically limited to 193mph, marginally lower due to drivetrain losses. These figures underscore Alpina's focus on enhancing performance while maintaining the car’s luxury credentials.
The improvements in power and torque are achieved through several technical enhancements. The adoption of BMW’s Valvetronic throttle-less intake system allows for more precise control of the engine’s breathing, leading to increased efficiency and responsiveness. Additional tweaks to the engine management system and turbocharging setup further contribute to the 40hp and 22lb-ft gains over the previous model. These changes enable the B7 to deliver strong acceleration and sustained high-speed cruising, characteristics expected in this segment.
Aerodynamic and Cooling Enhancements
Alpina says the 2013 B7 features over 30 new components, with changes concentrated on the front end to channel more cooling air and manage the increased heat from the uprated engine. These modifications include revised bodywork and aerodynamic elements that not only improve cooling efficiency but also contribute to the car’s overall stability at high speeds. Such upgrades are essential to ensure the reliability and performance of a car boasting over 500 horsepower.
Model Range and Pricing
Both the standard and long-wheelbase models are available, with a choice of rear-wheel drive (sDrive) or BMW’s xDrive all-wheel drive. This flexibility allows buyers to select a configuration that best suits their preferences, whether prioritising rear-wheel-drive dynamics or all-weather capability. Pricing starts at $128,495 for the standard-wheelbase B7, with the long-wheelbase xDrive model reaching $135,395. All prices include shipping. These figures place the B7 in the upper echelon of luxury performance saloons, reflecting its exclusivity and engineering.
| Model | Drivetrain | Wheelbase | Price (USD, incl. shipping) |
|---|---|---|---|
| B7 sDrive | Rear-wheel drive | Standard | $128,495 |
| B7 xDrive | All-wheel drive | Standard | $131,495 |
| B7 LWB sDrive | Rear-wheel drive | Long | $132,395 |
| B7 LWB xDrive | All-wheel drive | Long | $135,395 |
Comparison to Other BMW Models
The 2013 Alpina B7’s 540hp output puts it comfortably ahead of the standard BMW 750i, which produces less power and is not tuned for the same level of performance. While the BMW M5 offers similar horsepower, the B7 delivers this in a larger, more luxurious saloon body, appealing to those who want high performance without sacrificing space or comfort. This positions the B7 as a unique option for buyers seeking both executive luxury and significant speed.
