Pursuant to Rule 461 under the Securities Act of 1933, as amended (the “Act”), Aeva Technologies, Inc. (the “Company”) hereby requests that the effective date and time of the above-referenced registration statement (the “Registration Statement”) be accelerated to July 24, 2021, at 4:00 p.m., Eastern Time, or at such later time as the Company or its counsel may orally request via telephone call to the staff of the Division of Corporation Finance of the Securities and Exchange Commission (the “Commission”). In making this acceleration request, the Company acknowledges that it is aware of its responsibilities under the Act.

In connection with the foregoing, the Company hereby acknowledges the following:

• should the Commission or the staff of the Commission, acting pursuant to delegated authority, declare the Registration Statement effective, it does not foreclose the Commission from taking any action with respect to the Registration Statement;

• the action of the Commission or the staff of the Commission, acting pursuant to delegated authority, in declaring the Registration Statement effective, does not relieve the Company from its full responsibility for the adequacy and accuracy of the disclosure in the Registration Statement; and

• the Company may not assert staff comments and the declaration of effectiveness as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.

If you have any questions regarding this request, please contact Heidi Mayon of Goodwin Procter LLP at (650) 752-3227.
